is this true?

[xxxplosive]

workin out your biceps too much, and getting them big effects your throwing in a bad way?

[LD_18]

yes it is possible that they could effect your throwin, but they would have to be extremly big! if your arms are average or even a lil bigger than average it souldn't effect it too much. but in general biceps are not as important in baseball.

Hell yes! It will tighten up your arm a lot. Stretch stretch strectch...

for me, it doesn't matter so much about my biceps....its more about having loose triceps and shoulders....espicially shoulders.....if any of your muscle groups are tight its going to be tough to throw, so be sure to stretch and do your thera band exercises
