Question about curls/biceps?

Question

First of all, both of my arms can do the same amount of curls. If I do curls with both arms untill I can not do anymore, and I set the weights down, I feel the burn in my right arm, but not my left. They are both tired, because I did as many as I could, but I olny feel the burn in one of my arms afterwards. No matter how many curls I do with my left arm, I can never feel the burn. If this helps, I am 15 and right handed. Does anyone have any explanation for this? Also, it seems like it has always been this way, so it's not anything new.

Answer 1

It sounds like you are possibly using your body when you single curl with your left arm. Try using a preacher bench so that only your bicep is doing the work.
