Have you ever wondered why some people seem to pack on the muscle in a short period of time, while others might be overjoyed when you put on 5-6 lbs of lean body mass in a year?
It’s about how much muscle can you build and the answer isn’t just so straight forward or simple.
Consider the following: The average man has between 30% to as much as 60% of his lean body mass as actual muscle. The average women has between 25% to 50% of her lean body mass as actual muscle.
Muscular growth is rarely a liner process and tends to come in a series of cycles.
“You cannot calculate your actual muscle gain, short of having a biopsy.” – Jeremy Likeness, Certified Personal Trainer and Body Transformation Expert
That means that no matter what you eat, how hard you train or what supplements you take, muscle growth will never come at a predicable steady rate. This makes those 10-12 pounds of muscle a year for a natural bodybuilder a myth along with any other hard numbers telling you how much actual muscle to expect or any references to the actual rate of growth.
Here’s just a short list of the things that can influence your muscle growth:
- complications called “life”
- and more…
By the way…
Some people are genetically predisposed at packing on lean body mass and can just look at a weight and gain muscle (you know those people right?). Others have to work like the dickens to just gain an ounce of muscle and their rate of growth is slower.
Researchers from the Netherlands, Van Etten, L.M., Verstappen, F.T., & Westerterp, K.R. studied the effect of body build on weight-training-induced adaptations in body composition and muscular strength. Medicine and Science in Sports and Exercise, 26, 515-521. In the study they found that men with a “solid” build gained more muscle than men with a “slender” build following a 12-week weight-training program .
Although fat-free mass increased in both groups, the slender guys gained only 0.7 pounds (0.3 kilograms) versus 3.5 pounds (1.6 kilograms) in the solid group. My point is…
The nearer you get to your muscular genetic potential, the slower the gains will be. This is known by exercise professionals as the ceiling of adaptation. The longer you’ve been training, the slower your gains will be. Somebody like me who’s been training for 17 years will gain less muscle mass than a new trainer who’s just started out in the first 6 weeks.
So what does this mean to you?
That being said, based on the consensus of the available studies, the average trainee can gain roughly 2-4% of their initial weight in the form of muscle after 6 weeks of regular resistance exercise. These figures are based on the results of studies using trained subjects with a body fat percentage of 10-15%. Extremely lean or obese individuals would be hard to predict.
None of the studies I could find made reference to a female’s ability to build muscle so my best guess is about half of the male studies but I can’t prove that as there’s no research to fall back on. Let’s face it…
How much muscle can I gain is not a linear approach. You won’t keep growing at the same rate forever. In fact, the studies that do reference muscle growth were only on male trainees in the first 6 weeks of training. That seems somewhat predictable but after those 6 weeks, you need to know what to expect and it’s not going to be the same number week after week or year after year.
Over the course of a year, it’s rare for people to add more than 25 lbs of muscle but it’s very possible for them to add more than 25 lbs of lean body mass. Lean body mass defined as a combination of anything that is not fat. And that’s why…
Increasing your lean body mass is something you can track and calculate and should be your focal point to determine your progression. How much muscle you build in a given time period is not because it’s not a linear process and it can’t realistically be determined short of a biopsy.
“A beginner on a decent training and nutrition program might be able to gain 25 pounds of muscle in their first year of training. In year two, we can cut that number in half, giving you a gain of 10-12 pounds. In year three, the gains will be halved again, giving you 5-6 pounds of new muscle.” – Christin
If you are gaining more lean body mass that is generally a positive because you are gaining more muscle than fat. For most weight-gainers, .5 pounds per week would be an even more realistic goal as they reach their genetic limit. Frankly…
Staying focused on your goal by training intensely, eating consistency and engaging in proper recovery are things you can control and will result in your optimization of lean body mass.
Remember that gaining muscle is a long-term project. If you’re dedicated and consistent in your efforts, you will not be disappointed.
