Hi! I've used cathe for a few months and i really like her! before cathe, i was using the firm tapes for about a year and noticed some definition, but not too much (i'm pretty active-I run, swim, play soccer and basketball). but, i feel like i get my best workouts from tapes! anywho...i'd like to check out some more of cathe's stuff, but there is such a large selection, i'm not sure what to get! i currently have IMAX (I love it, but could use something a little more difficult), powerhour, max intensity strength, circuit max, cardio kicks (love this one too, but need something a little more intense), and max intensity cardio. I'm looking for more cardio-fun, tough, without too much choreography, and strength tapes. any suggestions would be greatly appreciated. i think i'll be going with the dvds too. i've thought about both the intensity series along with the new series, but was wondering if i could just get away with the terminator for the intensity series, or just a few of the others (buying both sets is kind of expensive and i'm afraid i would be overwhelmed with that many new workouts!). thanks!
