I get questions all the time from normal guys who are 5’10” but want to be a ripped 190lb. This tells me there is a huge misconception about how much muscle the average man can gain naturally. This perception is skewed by muscle magazines that promote bodybuilders who take steroids on their covers.
The following digs deeper into this question of maximum muscle potential for men and offers some equations you can use to estimate how much muscle you can gain naturally.
Unnatural vs. Natural Physiques
If you see a 250lb bodybuilder with veins popping out all over the place, you can be sure that dude not only takes steroids, but a bunch of mostly illegal, dangerous supplements, referred to as a “stack”. Not only are 99% of bodybuilders taking steroids, even a large percentage of fitness models (men and women) who promote supplements take steroids, or HGH (human growth hormone). I wish it weren’t true, but sadly, this is what I’ve learned being part of the fitness industry.
Natural Bodybuilders (sample photo to the right) who comprise a very small percentage of the bodybuilding industry do not take any steroids, or other heavy-duty, performance enhancing substances.
NOTE: All the formulas to arrive at your maximum muscle potential in this article are based on natural male bodybuilders who are extremely dedicated individuals and have lifted for oftentimes 10+ years.
The Genetic Bell Curve
The bell curve can be applied to body type to arrive at what percentage of people will experience average, above average, or below average muscle mass development. If you remember statistics, this genetic bell curve implies about 68% of people are average (within 1 standard deviation of the mean), 16% are below average, and 16% are above average.
People who are “average” will respond by gaining muscle over time with solid training and nutrition, and will be statistically average in terms of total muscle potential. The formulas in this article are based upon this genetic average. The 16% of people who are “below average” will not genetically be able to put on as much muscle despite using the same exercise, or nutrition regimen. The 16% who are “above average” can get bigger just by looking at weights! I’m sure you’ve seen, or know a guy like this.
