I used to have some of her stuff, and her body is really inspiring, but after discovering Cathe's videos Karen went right out the window w/all my other tapes. Mostly this is b/c I don't do any strength training at home though, so maybe she'd work for others here. Also I had her Pure & Simple Stretch which was really nice but too long to work into my schedule.
But as far as her cardio workouts go, she's so lame compared to Cathe.
