Body shots

Of course you could just spar..

I've seen it done by pros even like Manny Pacquiao down to just your regular gym rat. Some will use medicine balls, a heavy stick, or just a boxing glove.. flex your abs and they'll start smacking you in the abs with the said item. That hurts like a *****.
