I have done this twice and just wanted to comment that this is a great total body workout. I don't own a barbell, but free weights works just fine for me. I love the premix with the plate bonus. With the changing rep patterns, this adds a nice cardio effect. I like that it's not overkill but a nice muscle burn. Easier on the back. It's an hour long so I save this for the weekend. So glad I purchased this one. I am finding the original STS Total Body a big winner also.
