When I work out my biceps I do:
1: 4x15 chin ups (84 kg me)
2: 4x15 barbell curls (30 kg)
3: 4x12 concentration curls (22kg)
4: 4x12 cable preacher curls (62 kg)
My problem is with my forearms ,they hurt badly when I start doing barbell curls but not while I am training but when I am done with each set of 15.
Is this a problem with how I am holding my arms?Am I using the wrong barbell maybe?Or my forearms just cant handle this much weight?
EDIT:
I realized I have this type of pain :https://www.youtube.com/watch?v=CudqmKQIRRA
