I re-visited this video today and I had forgotten what an effective step interval workout it is. Similiar to the IMAXes, except she allows (if you choose) a 2 minute recovery. Its more like the blast only premixes with a longer recovery period. But you have the option of intensifying while she is showing the next move if you want to, making a 2 minute interval with 1 minute recovery. It is so versatile for the beginner to advanced interval training regiman. The interval is 1 minute, but there is a time graph so you can do anywhere from 15 seconds to the full minute as you progress. Anyway, just thought I would pass this along for anyone. The total workout length with warmup and stretch is 48 minutes. The intervals go for 30 minutes.
