How To Diet To Build Lean Muscle

By Russ Howe

Everybody has different goals in the gym, but usually they revolve around learning how to lose weight or build lean muscle mass. If you are to do either, however, you will need to discover how to build your diet plan to suit your individual goal. Diet is the most overlooked part of any workout routine, and overlooking this aspect is a very costly mistake to make.

You needn't worry, though. Learning how to do this is not very complex at all.

Fat loss is a common goal in the gym. However, ninety percent of people who list this as their primary goal have overlooked the one aspect which is going to get them there - their daily calorie intake. The basic science behind fat loss is that if you eat less, you will lose more.

However, it would be quite foolish to set yourself a good calorie target and then neglect to go a little bit further. By learning how to optimize your intake of protein, carbohydrates and fats you will only enhance your results even further.

If you need assistance in creating a solid calorie target for building lean size and retaining it, try the following equation. While everybody is free to tinker with it and strike a balance which works for them, the basis of this equation works for the vast majority of individuals:

* Total daily calories = target body weight in pounds x 15.

So for someone who wanted to be 180 lbs, they would multiply 180 x 15. This will give that individual a daily calorie target of 2700.

* Total daily protein intake = 30% of overall calories divided by 4.

Getting the right split of the three macronutrients is critical to ensuring your calories are coming from the right places. For protein, we can establish that 30% of 2700 is 810 calories. Now divide this by four and you'll be given a target of 202 grams per day.

* Total daily carbohydrate intake = 55% of overall calories divided by 4.

For our daily intake of carbohydrates, we need to do a similar equation with some slightly larger figures. 55% of 2700 is, of course, 1485. Divide this by four and we get 371 grams of carbohydrates.

* Your daily fat intake = Take 15% of your total calorie figure and divide the answer by nine.

Our body still needs to consume fats if we are going to achieve our fitness goals. It is a vital macronutrient. So to establish your fat intake, we need 15% of our calorie goal. This is 405. We then divide this by 9, which is the number of calories in one gram of fat, and we can see that our daily intake of fats should be around 45 grams.

Alongside your other two macronutrients and your total calorie target, you now have the foundation of a proven muscle building diet. Alternatively, if your goal is to learn how to lose weight you can enjoy similar success by simply playing around with this proven principle and finding a balance which works for your body.

Tips for staying fit after 50

By Silversurfers

Fitness, it’s often assumed, is a young person’s game.


But staying fit isn’t just something you can do when you’re over 50 – it’s something you absolutely have to do. As you enter middle-age, you have an increased risk of contracting particular illnesses and conditions, from high blood pressure and high cholesterol to back and muscle pains, and even certain types of cancer.

Maintaining a healthy body and mind could help you stave off the effects of some of these age-related afflictions. And staying fit is much easier than you think, if you discover the exercise regime that works for you.



Finding the right exercise for you


There’s no one way to exercise: just as your body is different from another person’s, the fitness routine that suits you will vary too. Your friend, for instance, may swear by her regular workouts on the treadmill at her gym – but that doesn’t mean that approach is right for you as well.

Start by considering your likes and dislikes. Perhaps you don’t enjoy the thought of running or jogging: think instead about sports that incorporate running, like football, squash and tennis. Look for a local five-a-side league with a high percentage of older players, or inquire about squash courts in your local leisure centre. This way, you’ll receive the benefits of running while participating in another activity.

But team sports aren’t your only option. Creative workouts like Zumba – which combines Colombian dance rhythms with aerobic exercise – are especially popular with older women because they’re fun and can be easily enjoyed with friends.

Weight training is also important when you’re over 50. This helps maintain your muscle mass, which you lose as you get older. You may need to consult a fitness trainer when you start weight training, to ensure that you don’t start with weights that are too heavy and accidentally injure yourself. If you’re joining a gym for the first time, many offer a few hours with a personal trainer as standard for new members.



Maintaining a healthy body and mind


When crafting your fitness routine, you need to think about activating your mind as well as your body. Disciplines like Yoga and Pilates engage both mind and body, teaching principles of core stability, coordination and helping to de-clutter your thoughts. Practicing even 10 minutes of Yoga or Pilates every day, in fact, can have a rejuvenating and energising effect. Another way to stimulate your brain is to vary your exercise routine – don’t stick to the same workout every day, and experiment with different sports and pastimes. This will make sure your mind stays engaged, and helps ensure that you don’t get bored.


If you’re having trouble motivating yourself, try looking for like-minded over-50s that want to stay fit too. Charity Silverfit, for instance, was created specifically to motivate over-50s to become active so it could be a great place to start.

You’ll also find plenty of resources online to get your fitness regime off on the right foot. Boots Web MD, for instance, has a range of nutrition advice and exercise tips for women over 50, while the NHS’s online Health and Fitness guide is handily divided by both gender and age range.

Upper & Lower Body Split – 3 Day & 4 Day Upper/Lower Routine

The upper/lower split is probably my personal favorite weight training split of them all.

It just works so damn perfectly for so many goals, situations and schedules that it tends to be the type of routine I end up using and recommending most often. Let me know you why…

What Is An Upper/Lower Body Split?


The upper/lower split is a type of weight training schedule that revolves around splitting the body up into 2 groups: upper body and lower body. Each group is then trained separately on its own workout day.

In most cases, the upper body workout would train the following muscle groups to some degree:
  • Chest
  • Back
  • Shoulders
  • Biceps
  • Triceps
On the other hand, the lower body workout would most often train these muscle groups to some degree:
  • Quads
  • Hamstrings
  • Calves
  • Lower Back
  • Abs

As for how the workouts are scheduled, there’s a few options. These are the most common…

The Classic 4 Day Upper/Lower Split


  • Monday: Upper Body Workout
  • Tuesday: Lower Body Workout
  • Wednesday: off
  • Thursday: Upper Body Workout
  • Friday: Lower Body Workout
  • Saturday: off
  • Sunday: off
The classic 4 day upper body and lower body split is probably the most common version. It involves doing 4 weight training workouts per week: 2 upper body workouts and 2 lower body workouts.

They are classically done using the 2 on/1 off/2 on/2 off format shown above, which allows for the added perk of having the weekends off (something many people prefer). Of course, the actual days you choose really doesn’t matter at all as long as that same format is kept intact.

This classic 4 day version of the upper/lower split allows for a frequency where each muscle group is trained once every 3rd or 4th day, which is right within the ideal frequency range for the majority of people who are past the beginner’s stage.

The Classic 3 Day Upper/Lower Split

Week 1

  • Monday: Upper Body Workout
  • Tuesday: off
  • Wednesday: Lower Body Workout
  • Thursday: off
  • Friday: Upper Body Workout
  • Saturday: off
  • Sunday: off

Week 2

  • Monday: Lower Body Workout
  • Tuesday: off
  • Wednesday: Upper Body Workout
  • Thursday: off
  • Friday: Lower Body Workout
  • Saturday: off
  • Sunday: off


The classic 3 day upper body and lower body split is probably a very close second in terms of how commonly used it is. It involves rotating through 3 weight training workouts per week: Upper Body, Lower Body, Upper Body one week, and then Lower Body, Upper Body, Lower Body the next.

You’d then continue alternating like this from week to week.

The workouts are classically done using the 1 on/1 off/1 on/1 off/1 on/2 off format shown above, which again allows for the added perk of having the weekends off (if that’s important to you). Once again, the actual days you choose really doesn’t matter at all as long as that same format is kept intact.

This classic 3 day version of the upper/lower split allows for a frequency where each muscle group is trained once every 4th or 5th day. While this is slightly less frequent than the classic 4 day version, it’s still perfectly within the ideal frequency range for the majority of people past the beginner’s stage.

3 Day Version VS 4 Day Version: Which is better for you?


Well, first of all, they both work extremely well and will both produce the results you want. So, in general, one version is NOT better than the other.

However, one version may suit you a bit better than the other. Here’s the most common reasons why…

If you can only manage to train 3 days per week (or if it would just be a lot more convenient for you to train 3 days per week), then the 3 day upper/lower split is definitely the better version for you. No question about it.

If you are someone who has an overall lower capacity to recover, then the slightly reduced training frequency of the 3 day version would definitely be better for you as well.

This could be due to age (recovery gets worse as we get older), having a highly stressful life (stress worsens recovery), having a very physical job (a lot of additional outside activity can hurt recovery), or just having crappy genetics. Hell, you may just be someone who feels better/stronger/fresher when they train slightly less often, in which case the extra day you have off in the 3 day upper/lower split will make a world of difference for you.

Other than that, there’s nothing that really sets either version apart from the other. So, just pick one.

Whichever variation you end up choosing, the upper/lower split is considered a moderate frequency split (not too high, not too low), so volume (exercises, sets, reps) should be kept equally moderate to allow for adequate recovery.

Are There Any Other Versions Of This Split?


Yup, there are. While these are definitely the 2 most popular versions of this split, there are indeed a few others. In fact, my brand new guide to The Best Workout Routines fully explains 2 NEW upper/lower split options, one of which is my personal favorite of them all.

What About Lower/Upper Instead?


If you’d prefer to switch the order of the workouts so that you start with the lower body workout (and it essentially becomes a lower/upper routine), that’s perfectly fine.

Who Does This Split Work Best For?


Honestly? The upper/lower body split works best for the majority of the population.

Whether you are a beginner, intermediate or advanced trainee. Whether you want to build muscle, lose fat, increase strength, improve performance or any combination thereof, the upper body and lower body split can ALWAYS be set up in a way that will be extremely effective for you.

As I mentioned earlier, this split allows for each muscle group to be trained between once every 3rd and 5th day (depending on which variation you choose), and literally all research looking into workout frequency shows that this is the frequency that works BEST for the majority of people who are past the beginner’s stage.

Real world results and my own first hand experience confirm this as well.

And, it just so happens that the upper/lower split is a perfectly balanced and amazingly adjustable way to reach that ideal frequency. That’s why it’s probably my favorite workout schedule of them all.

So, if you are an intermediate or advanced trainee, the upper and lower body workout routine is a fantastic choice for you no matter what your specific goal is. I highly recommend it.

5 Tips for Bigger Biceps

By Nick Tumminello

Here’s your step-by-step guide through 5 battle-tested biceps workout tips and training strategies we've used with athletes and bodybuilders to help them pump up their arms and build bigger biceps

1. Mix up your Force Angles to target the Biceps Peak
We all know that using a variety of exercises helps make our arm workouts (and all other weight training workouts for that matter) more versatile and more effective. But, it’s important to understand that simply changing the exercises doesn’t always mean you’re hitting your biceps in a different way.
You see, to thoroughly hit your biceps (or any other muscle group you’re training) you need to mix up the force angles, which changes the point of exercise (within the range of motion) where the muscle(s) is being maximally loaded, within a given workout.
Many lifters are under the impression that each time you change the exercise you’re changing the force angle. But this is not so, as many biceps curl exercises may look different - Example: Barbell biceps curls, EZ-bar curls and dumbbell biceps curls – but they may create the same force angle, which, therefore, hits your biceps in basically the same way.
Here’s a quick lesson on Biomechanics to help you better understand force angles:
All exercises that involve free weights and cables have a point within the range of motion (ROM) where the exercise is hardest on the muscle(s) involved, and where the exercise is the easiest. The point at which the exercise is most difficult is where the lever arm becomes the longest, which makes the muscles involved work the hardest.
During any style of biceps curl with a free weight (dumbbell, barbell or EZ-bar) the point at which your biceps is being maximally loaded (stimulated) is the point in the ROM in which your forearm is at a 90-degree angle with the load vector, which in the case of free-weights, gravity is your load vector.
In other words, when using free weights the point of maximal loading on your biceps (during a biceps curl) is when your elbow reaches 90 degrees of flexion or when your forearm is parallel to the floor.
When doing biceps curls using a cable column, the cable itself is the load vector and the point of maximal loading to your biceps here is when your forearm makes a 90-degree angle with the cable.
The nice thing about the cable column is that you can manipulate the force vector to make your biceps work the hardest in ranges of motion (of the biceps curl) that free weights miss.
Here’s a way we use a cable column to create a maximal force angle at the top point in the range of motion. In this video you’ll see how the 90-degree angle is created much higher in the ROM, which we use to maximally stimulate the biceps at the "peak" of the contraction.
Now, don’t get it twisted as I'm not saying you can isolate out any particular portion of your biceps (upper, middle or lower) when doing curls; you can't do that with any exercise for any muscle. But, as I’ve demonstrated in the video above, you certainly can manipulate the force angles during exercises to cause the point of maximal loading (on the biceps) to be at different points within the range of motion of a biceps curl.
2. Use an Offset Grip
Basic anatomy tells us that our biceps are not only elbow flexors, but they’re also forearm supinators. Based on this, we’ve found the best way to ensure maximal biceps recruitment when doing dumbbell biceps curls is to hit both (resisted) elbow flexion and forearm supination by holding the handle in a unique way.
Here’s a new gripping strategy we use, which I can promise will give you a much better biceps pump!
Instead of gripping the dumbbell from the middle (in the traditional manner), grip toward the thumb side with your hand as far to this side as possible.
Doing this will force you to resist forearm pronation by using more of your biceps as supinators while you perform the biceps dumbbell curl exercise as long as you perform them in the manner.
3. 60/30 Biceps Blaster
This biceps protocol has been one our favorites because it only takes 30 seconds to get your biceps swollen and pumped. And, its effectiveness surprises many lifters who when they first see it think it’s “gimmicky” because it’s so different than any biceps training methods they’ve seen before. We then explain to them A) if you always do what you’ve always done, you’ll always get what you’ve always got. And, we also teach them that B) there are three ways to increase muscle: Lift heavy (max effort), lift fast  (dynamic effort) or lift a lot (repetitive effort) – Our 30/60 Biceps protocol combines both moving fast (to create high intensity) and moving a lot (to create high work volume).
You're going to need a heavy-duty band for this workout.
Coaching Tips:
  • We use a band because it allows you to move fast without gaining its own momentum
     
  • We recommend using a 1/2-inch band for weaker individuals and a 1-inch band for stronger folks
     
  • Perform 60 reps in 30 seconds x 2- 4 sets with 1-2 minute rest
If you can't complete all 60 reps in the given time frame of 30 seconds, the band is too heavy.
4. Biceps 28s
Most lifters are already familiar with the classic biceps training method of using biceps curl 21s, which was popularized by bodybuilding legends like Arnold Schwarzenegger and adopted by virtually every young lifter looking to get bigger biceps. We developed our Performance U 28s rep protocol as a way to take 21s concept to create more time under-tension, a better biceps pump and add a new twist to classic method.
If you don’t already know: Biceps 21’s are where you perform 7 reps of partial range biceps curls going halfway down. Then you do 7 partial reps only going halfway up. Then, you finish with 7 more reps using a full range of motion. Totaling 21 reps.
How to Do the Performance U Biceps 28s Protocol
Perform the following four biceps curl variations seated, standing, or on a preacher bench (using either a barbell, dumbbell or EZ-bar) back-to-back, without rest:
  1. Perform 7 partial reps in the most difficult 1/3-1/2 of the range of motion
     
  2. Perform 7 full-range of motion reps
     
  3. Perform an isometric hold (pause) in the mid-range for 7 seconds
     
  4. Perform 7 partial reps in the easiest 1/3-1/2 of the range of motion
Now, there IS a method to the madness behind the way we perform our Biceps 28s protocol, which is based on the Force Vector concepts I shared earlier.
Here’s the thought process we used to designed our Biceps 28s protocol:
We begin with the most difficult part of the range when you’re most fresh.
The first 7 reps serve as a nice pre-fatigue before we hit 7 full range of motion reps. Plus, getting some movement started from the bottom can help you power through the end range you just focused on in the first 7 reps.
Muscle mechanics dictate that our muscles are strongest in their mid-range. That’s why we do an isometric hold in this range for 7 seconds. Plus, isometrics are a great way to increase time under tension. And, help bodybuilders better hold flexed positions, which is what they have to do when they pose in competition.
We finish with the easiest part of the exercise at the end, when you’re at your weakest and most fatigued from the previous 21 reps.
Now, what I've just explained is certainly not the one and only “magic order.” Occasionally, to create training variety, we’ll mix up the order a bit and perform our Biceps 28s like this:
  • 7 reps half way down curls w/ Pronated (palm down) grip
     
  • 7 reps half way up curls w/ Neutral grip (palms facing each other)
     
  • 7 reps full ROM supinated grip (palms up)
     
  • 7 seconds midrange isometric hold (any grip you wish)
Of course, these are all done in the same manner as the above, back-to-back, without putting the weight down.
5. Constant Tension, Mid-Range Biceps Curls
One of the fundamental concepts in muscle physiology is the length-tension relationship, which is: how much force a muscle can generate relative to its length.
Muscles tend to have the lowest potential to generate force when they're either fully elongated (stretched) or fully shortened (contracted). And, as I stated above, muscles tend to generate the highest possible force in the middle — halfway through the range of motion (aka. The mid-range).
Not only are muscles able to produce the most force in the midrange, they also have the potential to activate the highest percentage of motor units. (A motor unit is a nerve cell and the set of muscle fibers it's responsible for activating).
Put simply, more motor unit recruitment means you’re able to bring more muscle into the game on each rep, provided the effort is high enough, as shown in the following graph.
Now that you understand that muscles produce the most force in the midrange, where they also have the potential to activate the highest percentage of motor units, you can better appreciate how to exploit these concepts and transform exercise science into practical exercise application with what we call Constant Tension Mid-Range Biceps Curls.
Instead of doing full range of motion biceps curls (standing with Dumbbells, a Barbell for an EZ-Bar), we begin from a 90 degree elbow bend (i.e. the mid-range) and perform partial rep curls in the middle of the range.
In other words, with elbows by your sides, you perform biceps curls without ever fully going to the bottom or the top of the range of motion.
We prefer to do our Constant Tension Mid-Range Biceps Curls for time instead of for reps, as it doesn't matter how fast you move because you’re always under tension and using a timed interval ensures that you get our desired time under tension, which is 40 to 60 seconds, regardless of the tempo you perform each mid-range curl at.
Closing Comments
The traditional biceps exercises we all know and love are still just as great and effective as ever before. Heck, most of the biceps training strategies I shared above are simply new twists on classic biceps building concepts. While we embrace old-school wisdom, as you've seen, we also use some new school biceps building protocols, which you can now to add to your own biceps-training toolbox.

Are Kettlebells Or Dumbbells Superior For Gym Based Strength Gains?

By Russ Howe

It's a war which has raged on for the best part of ten years but, thanks to recent scientific research, today you will get a definite answer to the question: Kettlebells vs dumbbells - which method will give you the best results?

Before we do that, it is important to point out that using both approaches is always going to be far superior to limiting yourself to just one style. You will often hear people swearing by the use of just one protocol, all this does is limit your ability on the gym floor as each style comes with it's own plus points and negatives, therefore a combination of the two styles alongside other forms of training, such as yoga, interval training and body weight movements, would be optimal for achieving the goals set by most individuals.

However, a recent study pitted the kettlebell against free weights in a study to determine which method would return the greatest strength gains overall. The results were quite profound.

In the study, researchers ordered their first group of subjects to perform a six week course of swings, goblet squats and accelerated swings using a 35 pound weight. Improvements of squat ability, vertical leap and power clean strength were documented.

The free weights group performed a six week program of barbell squat, power clean and high pull using around 80% of their one rep max on each exercise.

At the end of the six week study, the results of the two groups were compiled and compared. The overwhelming winner was the second group - the free weight group. These individuals boasted improvements of a 15% higher squat compared to group A's 5% increase. They also noticed a 10% power clean and 4% vertical leap boost.

Their kettlebell counterparts, on the other hand, could only manage a 4% increase to their power clean and added just 1% to their vertical leap. Those results were quite surprising, given the explosive nature of kettlebell training in general.

If you want to base your training program purely on the scientific findings, then free weights clearly return the greatest strength gains.

However, the optimal method for building a better body through effective fat loss and lean muscle building should include a variety of techniques. Although this particular study from California State University, Fullerton returned results heavily in favor of resistance training, this does not mean you should eliminate every other type of exercise from your program.

While free weights have now been shown to trump other equipment in the strength category, that doesn't mean they are the only method you should use. For instance, there are a number of exercises which can be performed using a kettlebell which are simply more functional than using conventional dumbbells and barbells. The swing is a perfect example of that.

The battle between kettlebells vs dumbbells will be one that undoubtedly cuts most gyms down the middle depending upon personal choice. However, the latest scientific research clearly documents one winner.

How to Get Lean Muscle - Lifting Heavy Weights VS Lifting Light Weights

by Cheng Kee

If you're new to building lean muscle, you usually have a choice between two different kinds of weights: heavy weights and light weights. Light weights are obviously easier to lift and as a result, you can lift them for a longer period, but many professional body builders say that lifting heavy weights is the only way to build lean muscle. This article will discuss the difference and which weight you need to lift if you want to build lean muscle.

Lifting light weights is typically only useful for one thing: burning calories. Say you lifted a light weight 20 times and you could lift a weight twice the mass of the light one 10 times, you would not build muscle by lifting the lighter one. To better explain it, use logic to show why it makes sense. If you lift a pencil 1,000,000 times a day you might be doing the same amount of work as lifting a 10 kg weight 10 times a day. However, doing the same amount of work does not equate to the same results.

You aren't putting any pressure on your muscles by lifting a pencil 1,000,000 times a day, while lifting a 10 kg weight 10 times a day would require more muscular focus as you're lifting. Lifting heavy weights helps you build lean muscle, but you have to lift them for a considerable amount of repetitions. What do you think would build more lean muscle? lifting 20 kgs once or 5 kgs 4 times? It's the latter, since your muscle has to be focused for longer.

So how about when you have a muscle building program and it tells you to follow a strict lifting schedule, like 3 sets of 15 reps. Should you opt for lifting a heavy weight and failing to finish the sets or using a lighter weight, finishing the sets but not really putting your muscles under any major strain? In this case, it's better to lift with heavier weights to push your muscles to failure. You shouldn't be bound by how many sets or reps you do. You should listen to your body for which weight it reacts to better. Having said that, don't lift an outrageously heavy weight. If you want to build muscle, lift a heavy weight many times.

How to Get Lean Muscle - How to Cut Fat 23 Hours After Your Workout

by Cheng Kee

That would be a weightlifter/model's dream come true, wouldn't it? To work out for about an hour, then go about your life doing other things and still have fat melting off your body. The muscle industry and commercial shows like "The Biggest Loser" have popularized the motif, "no pain, no gain." Which is true, if you want to effectively lose weight. However, if you want to lose fat, not weight (yes there is a difference), you'll want to work out as short as possible while maximizing muscular gain. Stop doing cardio and learn how to cut fat the efficient way.

See, the problem with cardio is that once you stop doing it, you stop cutting fat. Also, when you're doing cardio you can't help but lose muscle as well. Cardio is akin to long distance running. It's all aerobic exercise which will strip your body of muscle to fuel the exercise, then turn to the emergency storage, fat. Unless you want to lose all the muscle that you spent forever gaining, then by all means keep on doing cardio. But if you want to keep your muscle and lose fat, you'll want to do more of what you're doing to gain muscle. That's right, by lifting weights, you can get shredded. Sounds crazy but it's true!

What's the golden rule of cutting fat? The amount of energy you take in has to be less than the energy you lose from working out, right? Keeping this in mind, cardio does work because you do burn more energy than you take in. The reason why it's not very efficient is because, like we discussed, our fat loss ends when the workout ends and our muscle density is also compromised. The reason why weight lifting is the way to go is because it's a very fast way to reach an energy deficit (by pushing your muscles to muscle overload).

In the recovery stage, your muscles are rebuilding themselves and your metabolism will speed up and try and reach a state of equilibrium in your body by turning to your emergency fat storages. This might last for 2 or 3 hours, depending on how intense your work out was. Or it could last a whole 23 hours after a one hour work out. You could be watching TV, reading a book, playing poker with your mates, whatever... you can theoretically lose fat while just chilling essentially.

This does work but of course, you'll need proper guidance, a well structured work out routine and a dependable meal plan to make sure your body can handle such a dynamic change.
