Query: Body Damaging

This video is awful. Jillian has you up and down and swinging weights with terrible form. I had been working out 4 to 6 days a week for 2 years and bought a few of her videos because I know her routines are supposed to be so intense and I wanted to break a plateau. I only ended up hurting my back badly. This injury has set me back for months now.Just because someone was hired by a network to "run" a fat camp doesn't mean she is a top notch fitness instructor. Lesson learned the hard way I guess.
