Title: Kills your knees
Product review: I did the level one for 10 days and my knee began to ache around day 6/7 and thought it would wear off and just needed extra stretching. Fast forward to level 2, day 2 KILLER knee, popping sounds, etc, can barely move around. I am a runner and average weight at 110 lbs (average 10-12 miles/week) and never had any knee issues. I attributed it to the lunges in level 2, but perhaps it is the jumping jacks, not sure. I am going to stick to running and try the ab workout dvd instead.
Would you say this review depicts the product in a flattering or unflattering light?
