Query: good video

I like this video. I work up and sweat and can feel where I've worked my thighs and butt:)Although my knees can't handle the surrender excercise or anything to do with the chair. I feel a sharp pain in my right knee, it's usually the one that gives me trouble anyway. I just modifiy by doing deadlifts!Jillian's personailty can be over bearing. I did level 1 for a while and did level 2 today. She's just as annoying in L2 :/If you can get pass that, it's a good workout for the lower body
