Title: Can be hard on the knees
Review: I just did this dvd for the first time. I feel it in my thighs and abs. It's harder than it looks and requires careful attention to positioning. The instructor is annoying, but the workout itself is worthwhile. I will probably need a few more attempts to get the exercises done right because some moves are really subtle. There is no cardio section, so it's not a complete workout program in itself.
