text: where can i find an intense workout to drasticially improve pitching velocity?   throwing in general is done with your legs, with that energy transferred through your trunk to your shoulders and arms.  i'm sure you're already on a total workout program, but don't skimp on the abdominals work.  if your abs aren't strong, the energy generated by your legs can be lost there.  also, throw a lot.  that's really the only way to get increases in velocity.  i played baseball over the summer and that was really the only throwing i did.  then in 10th grade, i played football (qb) and baseball (catcher).  by the time i graduated, i was throwing over 80mph, just in those three years because i threw so much.
