Are there medicine ball exercises you consider indespensable? Most searches yield little more than a bunch of twisting abdominal exercises.
If I'm in the market for one, what brand, weight and material should I look for? I need something that can take a beating, obviously. The gym I'm using at the moment has a set of Dynamax medicine balls and I tend to stick to the 20lb. for slams, but it seems like they're not holding up very well.
I appreciate any input.
