I bet your balance isn't as bad as mine!
Although it's definitely improved from these classes.
Yesterday we had a totally different kind of class. The only tools were a set of heavier and medium weights. Basically, it was 5 sets of eight minutes each. Each set was 2 minutes cardio, 2 min. strength X 2. Every set was different, some not so bad, some horribly hard! I could barely move yesterday, although I think it was more the cumulative effects of step class, my body conditioning DVD, and Nordic skiing.
