left arm bigger then right arm!

[r3covery]

My friends arm is 3/4 of an inch smaller then his right arm. We have been lifting together for 3 months and he is able to do the same weight with both arms its not in his form. Does anyone know something he can do to help this. I know its natural for your dominate arm to be bigger but this is 3/4 of an inch. thanks.

my dominant arm is shorter than my other, but barely, but im a freak anyway. I'm 6 foot and have a wingspan of 6 foot 7.

using DB instead of BB is usually the first thing to say.

make sure that you don't always start reps with one hand.. usually when we get tired we will struggle with the first arm to do the movement and stop without even thinking or remembering we did it.

make sure you don't lean to one side or another.. little things focus on what you could be doing wrong or leaving out.. not insulting you, even pro body builders have coaches to make sure they are doing stuff properly and don't cheat.

make sure when doing things like picking up something or doing something in your normal everyday life that you trade hands..
