Hi! I have a question. I have developed little more the left side of my chest, why? Pheraps I do the exercises with the bad form?
Bro, nobody can tell out of just that information, but yes... it might be bad form, it might also be because you are left handed or something else like that. It's normal that the side you use the most, legs, arms etc. is a little stronger than the other.
Bro I'm right handed😂
Then it's probably just bad form / you use your left more / put more of your weight on the left side.
How can I Fix?
Do less, do it slower and keep doing that until you 100% feel comfortable with your form, I can' tell if your form is wrong or not, without having seen it, but it might be the problem, also if you have good form, then try to feel if you put more weight on your left side.
