Ok, we have a punchbag lying around at our gym and I usually mess around on it after hitting the heavy bag. The bag is about half size, fairly solid but with some give in it. No-one's ever shown me any drills so I've come up with stuff on my own. * I squeeze the bag between my thighs in mount position and guard position. I like to take a high mount and crush the guys arms together. I never bother trying to squeeze the other guy when I'm in guard but I've had people do it to me and I think it would be beneficial to develop sick bone-crushing power in my thighs. * I practice transitions from position to position, spinning on my knee. I try to grind my knee into the bag as hard as possible while pulling up on the end of the bag. I don't usually do this to live training partners but I'm basically aiming at being able to crush people into little piles of goo with my knee. * I practice GnP from various positions. I mainly use hammerfists from mount and the mount Shogun KOed Arona from. I try throwing elbows and knees from side position too. * I practice triangle choking the bag both ways. This is difficult as it's almost too big. Again, I'm aiming to develop horrible power in my triangle. I'm planning to experiment with wrapping a belt around the bag and practicing collar chokes as if the bag were someone's neck and the belt the collar. Also I've tried picking the bag up and shouldering it like a fireman's carry or something. I wonder if anyone else has any ideas/drills they use on a bag like this? Am I on the right track?
