I confess that I have forearms like a 15 yr old guy. And I feel that my bicep curls are being limited by my forearms. I am not experiencing the pump I used to experience in my biceps when working out biceps. When lifting up, the strength and the pain in the forearms is what I think is limiting me to go fully up (without compromising the form).
My question is
1. Does this reasoning even sound right?
2. If so, what to do now? Should I train my forearms more frequently (many people seem to be against that)?
3. So if the width is limited by the bone size, I can't increase the size of my forearms especially near the wrists?
