I haven't tried this new wave thing from the Firm, but I do use the Body Sculpting System 2 with the fanny lifter and sculpting stick. I must say, it is really great. I love the Firm. I'd probably try this as well but I just recently started using the BSS2 videos again. But I do see results already, which is awesome! I started about week ago. But if you do try the wave, please let us know! I'm curious about it too!
And to be honest, I find myself using these workout tapes more than going to the gym. They really kick your @ss, but you feel amazing when you're done.
