DD's 12U team had some 2 and 3lb balls they incorporated into the work out. Kind of a waste of time. The girls all complained of wrist pain when hitting them so they wouldn't hit them hard. I bought some TCS balls and DD hits them with gusto. No complaints of wrist pain and I have to stop her at 18-24 reps.
Can you hit them off the T as well?
