I forgot how intense this video was...I haven't done it in a while, but I did it the other day and wow...What a workout! Karen works every part of your body; lower body, upper body, abs, and stretch. Pretty intense cardio moves - apparently, the sprinting really boosts your aerobic capacity; this will increase your cardio strength. I really enjoyed this video just like all the other reviewers did. However, I am in excellent aerobic shape, just like all the other aerobic animals, and I got a workout, so for those of you who haven't tried this tape, this is don't miss tape...
