For some reason there's been a myth blown up into borderline gospel by weightlifters, and that myth is that a bigger muscle is a stronger muscle.
The baffling thing about this myth is that if you watch the Olympics–where the strongest weightlifters on earth compete against one another–most of the lifters don't even look overly muscular.
This is because these individuals train with one goal in mind, gaining strength on quick and explosive movements.
Training For Strength Vs. Training For Growth
Once you progress past the “starter gains” in muscle size and strength that always comes when people begin to go to the gym seriously, you need to make a choice about whether you want to focus on training for strength or training for growth.
That isn't to say that if you train for growth, you won't get stronger, or if you train for strength, you won't get bigger, it's just about understanding that there are different ways to train to accomplish different goals.
If you train to maximize the strength of your fast twitch muscle fibers and explosiveness, you will indeed become very strong, but you will not induce much hypertrophy in your muscles. This is because when you train for strength, you will focus on lifting very heavy weights for only a few reps.
When you are constantly trying to push your ORM (One Rep Max) higher and higher every time you go into the gym, you are actually training your CNS (central nervous system) to work more effectively and efficiently with your neuromuscular system. This trains your muscle to use all of its available energy to produce more and more force with the muscle that you currently have.
In fact, the lower the rep range you train with is, the more likely it is that you are limiting your growth potential.
While there are some exceptions, the vast majority of successful bodybuilders train with a priority on growth.
This means that they use enough weight to stimulate the muscle fully, but they do not make it so heavy that it could pose a high risk of injury. They ensure that the weight is light enough that they can complete 12 full repetitions with perfect form.
The reason why so many bodybuilders do this is simply because this is the optimal way to achieve hypertrophy (maximum muscle growth) in the target muscles that they are training.
Olympic Lifts And One Rep Maxes Train for Strength, Not Growth
If you want to be as strong as possible and you are doing olympic lifts and one rep maxes to gain athleticism, explosiveness, power, and strength, then by all means keep doing them.
But, if you are incorporating cleans, snatches, one rep maxes, etc. into your routine thinking that it is helping you gain size, completely stop doing those exercises entirely.
Professional bodybuilders mainly train for growth in order to look the way they do, so if your goal is to build a physique like a bodybuilder than training for growth is what you should do.
Besides being inefficient for helping you grow bigger, when you constantly do olympic lifts and one rep maxes, you are putting yourself at a much greater risk for injuries than if you trained for growth. This is the nature of training for strength, you only get stronger when you constantly are pushing the line of how much you can lift before failure. Unfortunately if you cross that line too far, it could have some disastrous consequences.
What Supplement Can Help Improve Both Your Muscular Size and Strength?
To put it simply, muscular size and strength is largely dictated by the amount of testosterone in your body.
While there are plenty of supplements out there that can aid the rate in which your muscles heal and grow, at the end of the day, these effects are always going to be minimal in comparison with a supplement that helps to boost the amount of testosterone in your body.
