This is higher impact than Core Cardio II, but the high impact segments are short enough that I can stay on my toes, so my knees did not bother me at all (and I work out on concrete!) I used a junior basketball instead of an oof! ball, and it worked fine, though I am not overwhelmed by an extra "fun" factor working with the ball. The abs section is useless, so ff past it, but the rest of the workout is quite intense. I object to doing the "hopscotch" move (8 hops on one leg - ouch!) and just do a run instead. I also leave out the weights for the very last segment with Carissa - marching and power jumps do not need dumbbells! I have found that I do keep the 3lbers for Tamela's segment with plyos - in spite of the fact that her knees look like they will collapse, I have not had any trouble doing those few plyos with weights (under control and landing softly, of course). I will use this tape quite often, because I get a great sweat going, and the variety of moves keeps it from getting boring.

Instructor Comments:
They are all bad, but Tamela takes the cake. Her form is awful, and "this is fun" seems to be her only line.
