hello! i am actually a turbo kick instructor, whichis created by the same person who created turbojam...the only difference is it is taught as an aerobics class in a gym. it's an AWESOME workout and lots of fun! the creator, chalene johnson, is very upbeat and the music is great. if you want to, pm me and tell me where you live and i could try to find a turbo kick class in your area and maybe you could check that out before you shell out the money for the dvds. hope this helps! jj
