Can You Shape Muscles?
If I had a dollar for every single time I saw a guy lifting lighter weights for higher reps claiming that it shapes and defines the muscle, I’d probably be a rich son of a gun. Okay, okay, probably not, but I’d be about 20 dollars richer than I am today. When I hear about shaping and sculpting a muscle, it usually has something to do with biceps and building that mountainous peak that everyone is ‘oh so crazy’ about. Can you shape muscles? Will doing exercises that claim to change the shape of your muscles really have an effect on you?
The answer to both questions sadly, is no. The common misconception that people usually have is: that they can change the shape of their muscle, or make a muscle more defined, by changing how they perform an exercise or how many reps that they do. They will do endless amounts of concentration curls to build up a bicep peak, or do a specific routine to give the shoulders a more defined and round look.
I’ll be completely honest with you, this is a load of bull crap.
Muscles can only do one thing, and that is to grow larger or smaller in size. When you perform a certain exercise, whether it’s biceps curls or chest press, all muscle fibers that are targeted are engaged at once. You cannot specifically choose what area to build up muscle fibers on your biceps or chest by turning your arms more, squeezing more, or whatever it may be.
The shapes of your muscles depend solely on your genetics. This is an unfortunate reality for most. If you were born with flat shaped biceps, or short biceps, chances are you are going to be able to do much to change that. You can only work your muscles and try to build them up and hope that your genetics will pull through for you.
