My personal opinion is that baseball players are best served with core work (exercise ball, stretching, etc.) than they are with dumbbells and bench press. But there should be a difference in workout routine between pitchers and position players. Lifting weights can be detrimental to your flexibility in the upper body. Pitchers for example should never bulk up their shoulders. It will kill the speed on your fastball because you can't torque your shoulder as much. Same thing will happen to the arms of position players but obviously some guys don't care about that (DH, 1st base, and guys who already had bad arms). So bulking up the upper body in baseball isn't always a good idea. You hear about Braun working on his core all the time and that makes perfect sense since that's where your power comes from - not your biceps.You can improve your core with minimal equipment - exercise ball, some small dumbbells, yoga mat, and those stretchy cord things. I realize the kids in the minors aren't given jack for per diem but it's on them to stay in shape. You can buy all the equipment I mentioned earlier for under $200 (and probably less if you get it used). Now if the Brewers aren't showing them or telling them how to use it or not telling them what they need to do to become a better player then shame on them.
