This workout is an interval session. I've found that after using it for 6-7 months, I still select it at least twice a week. I indeed did start by following the two people demonstrating "low impact" moves. Eventually I modeled myself on the 'advanced" Robin. Now, I've adapted by making larger arm movements, adding "plyo" to the low impact moves, etc., with the result that this is still a fine interval training tape. If you want to extend the workout, do your favorite floor routine while other videos are being previewed. Or, add the companion Functionally Fit: Lower Body Workout.

The intensity and difficulty of the two minute intervals seems to build (as opposed to the NAC Interval Challenge, for instance, where the middle intervals seem "easier" than the beginning and ending ones).

The tape is excellent in other ways. You can insert an interval from this into other tapes that have become "too easy". I have learned to add muscle and intensity to all sorts of activities.

I'm someone who doesn't want to buy a lot of tapes, and I highly recommend this.
