I ordered this because I had a stability ball and didn't know how to use it. The video is divided in 10 minutes for upper body, lower body and core. Time flies this way and before you know it it's done. Keli Roberts gives clear directions and is likeable. You need a ball, two sets of weights (I use 3 pounds and 10 lbs) and a mat (or carpeted area). The video is dynamic and inventive, I do it as often as possible and feel it in my body. Good job.
