coach has a good point.

The one thing I do applaud in your "sparring" sessions is that you guys are making a genuine effort to box with style and form and aren't just flailing away like idiots.

Having said that, wouldn't it make perfect sense for you guys to join a gym and really LEARN how to box? Hell, one day you might even get paid for it.

But at the very least you guys should be wearing mouth guards and head gear and sparring lightly.
