Jillian Michael's 30 day shred

Re: Jillian Michael's 30 day shred

***I downloaded the Boost your doing Metabolism DVD and I find it exhilarating . I love the kick-boxing moves and punches !

I'm taking it slow and doing each circuit separately so that I won't injure my knees again !

Has anyone tried the Boost your metabolism Workout and what were the results ?
