I purchased this DVD over the weekend and immediately tried it out. Years ago I enjoyed Billy's Tae Bo DVD's, but have since been turned on by Tony Horton's P90 series and the way he uses weights to sculpt and have cardio intervals. I will agree that this DVD doesn't do a lot of lunges or anything for legs, but if you really push yourself to do as Billy says and "keep your butt down" during the squat sections, your legs should burn. The other reviews that say the legs aren't worked are just not really trying during the workouts. I have rarely sweated this much during a workout. Just be careful not to overdo it on the weights. I started with 8 lbs thinking that since I train with weights it would be fine, but I switched to 5 lbs. The movements start slow and get extremely fast like Tae Bo so if your weight is too heavy you reach muscle failure half way through, you start flinging your weights around, and you risk tearing muscles and injuring joints.
I am sore all the time and love this workout. I can't get enough!!! "You gotts push yourself. No one else is gonna push you so you gotta push yourself!" -Billy Blanks
