yeah, Jillian uses her kb on her Shred it with Weights dvd. I looked into it when I was buying my 1st one, but it doesn't get very good reviews from what I found.
I did my Lauren Brooks dvd Saturday and yesterday I was so sore I could barely move! I was shocked bc I workout 4-5 days a wk with my JM dvd's, with weights, and they are pretty tough workouts and just about every muscle was sore from using my 15 lb kb! I'm still sore today but it's bearable...
