Low Impact, High Intensity and Start Your Engines are great. I prefer Start Your Engines, but it really doesn't matter which tape you choose. Essentially they're the same workout.
Just be careful of the "big knees!" They are the equivalent of plyos in the Firm -- ENDLESS repetitions, and they really made my back hurt after 45 minutes!
