thanks for the videos Andre! I'll try picking up some materials at the hardware store to get going on some of these exercises--my balance is really bad!! :P haha

As it happens I have some other questions; if anybody can answer that would be grand!

1) I've read to keep your hands relaxed and not clench your fists, but when you throw a punch is it okay to clench your fist then? it seems natural for me to do it, but I want to make sure while I'm learning the basics that I'm doing it as exactly right as I can be.

2) My boxing coach said that its good to do sit ups as an exercise, I was wondering if situps could be replaced with crunches in this case or if there is a boxing-specific reason that situps should be preferred over crunches? thanks!
