Last time I did Boot Camp I tried something a little different, and I really liked it. After the minute of legs in each segment, I reversed the dvd and repeated it twice more. So, I had 1 minute cardio, 3 minutes legs, 1 minute upper body and 1 minute abs. I plan to do the same for upper body next time I do it. This gave me a great leg workout in addition to some cardio, upper, and abs work. It took longer, so I'll probably do this on a Saturday or Sunday when time isn't an issue.
