Title: Good but a bit hard on the knees
Review: I've tried his other videos and I feel this gives me the best workout, however he's very fond of lunges. I'm only 24 and I find myself in lots of pain if I do this video more than three times a week. I do not suggest this video for a beginner. I would say you should start a little bit gentler and then work your way to this. I've been using this for about two months and I've definitely noticed that I'm getting stronger.
