Thanks for your response. I have the ones that came out together that include Butts n Guts, etc. Someone jokingly referred to it as the sash series, the around the world series and the Murphy's law series, CTX, 4DS, PH, slow n heavy and, dunt dunt daaa, STS, which will remain in package for a few more months while I get back into my groove. I just wanted to add the IMAX 2 DVD and by the time I pay for that, I might as well take advantage of coupons and discounts this month and just get the Intensity series, which I've always wanted. My high step is new so I wanted some workouts for that, too. want want want. Ugh. I should throw that work out of my vocab!
