This is going to sound crazy. My current library includes alot of what was mentioned above, For starters, Jane Fonda-3 of her step tapes plus aerobic too. Keli Roberts. CherFitness, RealFitness, Step it Strong. Petra Kolber, most of her Reebok releases. Gin Miller,most of hers period-AeroStep is the best. Charlene Prickett and the Bench Boys (my first extreme advance step tape and still a kicker) plus a few more of hers. Also, The Firm Cross trainers and Tough Tape.
Cathe, I will be up to 17 DVDs by Friday cause I finally ordered KPC by reading all the threads.
Variety is the spice of life. I feel blessed to have what I got and all my VHS old ones are working good still.
Before Cathe, my standards were The Firm and Gin Miller with Keli Roberts.
