I frequently (once a week usually) do a little tough guy training for my abdominals. I find it toughens me up, and works my abdominals a bit. Anyway I usually do medicine ball drops from 6 feet high, where my partner throws a 10lb rubber medicine ball at my abdominals. The ball is thrown pretty hard, as no one in my gym will do this with me except my regular training partner b/c they think that throwing it with that force will hurt me. We also do an exercise I call “RAmbo Torture,” where you hang from the chin up bar, and your partner throws chops or punches at your mid section. Again no one except my training partner will do this hard enough - usually, if your nails aren’t trimmed up, you will draw a little blood from a finger or two from hitting their mid section - to give you an idea of the force used. Sometimes we also kick eachother in the midsection while the guy is on all fours, not very often though.
Anyway I was wondering if any of this stuff will damage my internal organs? I haven’t pissed blood yet btw.
