just BUMPing this up to see if anyone has joined since I posted this...
only when begged, pleaded to, or forced into it. I hate boxing. But when I do teach it, I go to www.turnstep.com and use other folks boxing moves there. You can get an endless amount of combinations to use for class. Some are plain stupid and childish and would make you cringe in embarrasement for the stupid aerobic bunny that tried to use the empty space between their ears, but there are quite a few movements that will keep you invigorated and fresh for as long as you need. Give it a try.
P.S. I went out to Sweden in March to visit a friend way up north in Lulea. You guys still got snow over there?
