I don't have to do much to make this workout harder--just add weights to the squats and do the lunges different. The rest is as tough or as light as you want it to be, but not just great for beginners.
Each area of the thigh and butt (inner, outer, hamstring) is worked with a set of squats in between. This a a tape in which you will truly feel the burn.
My only complaint are the lunges done at the end of the tape. Since I am not as strong I had to struggle to maintain proper support. The tape can also be made more difficult with the addition of ankle weights.
All in all a good bargain but watch your knees.
