hi! this is my first time using this and i think it may be dangerous! i can see i'm already spending too much time reading through threads when i should be out running!! anywho...i've never used a cathe video, but i've read that her videos are great. here's what i'm looking for. i would like to buy a good cardio video. i currently do several firm videos and i really love them (both old and new) my favorite is supercardio if that gives any ideas of my level. i don't think i want any sculpting stuff, i get enough of that with the firms, but i really want only cardio-which is typically hard to find with the firm videos. i guess i'd consider myself to be advanced, working out 5-6 times a week. i usually run 2-3 miles before i do any cardio or sculpting videos. does anyone have any suggestions for me? oh yeah, i'd also like something without a step, or something i could use the fanny lifter with (i don't want to have to go buy a new step right now). any suggestions would be great! thanks!
