The "boxing" part of boxing class turned out to be only a small portion of the hour. Most of the class was spent doing intense cardio. It went something like this: jump rope, jumping jacks, push ups, crunches, jabs and kicks. Repeat as fast as possible until you puke. I was in over my head from the beginning - I haven't jumped rope since elementary school. I couldn't hang, but I gave it my best shot and stayed for the entire hour. It was the hardest workout I have had in recent memory. I think I'll go again next week.
