Hi, I used to work out for about 20 years. I just took a year break off and really want to get back into the swing of things. I have many of Cathe's step tapes and want to focus right now on cardio. What tapes do you recommend that Cathe has just for cardio? Does she have any without using weights, just cardio? I joined back at the gym that is why I just want to order cardio tapes, no weights. BTW, I already do have cardio kicks. Thanks for your help.
