Query: Keli Roberts Total Body Circuit Training

This is my favorite video right now- I love running outside in the summer but I needed something other than the boring treadmill for the winter. Of the eight or so videos I now own, this is the best all around work-out. The time flies by and I finish feeling like I worked my entire body. It's broken up into segments so you step for a while, use the resistance band for a while, more step, more resistence, followed by the most intense step segment. My arms and thighs look much more toned. Keli is an excellent instructor because she knows what to say to keep you motivated and she doesn't have any fancy footwork- its all very easy to follow. I also enjoy her other step tape and I wish she had more videos!!
