It was either Step n Motion 2 or 3...I honestly can't remember. I was doing step at the gym, and wanted to start doing some workouts at home. I found Cathe in the Collage catalogue. They described her workouts as advanced. I decided to try Cathe because I thought my step classes at the gym were advanced...little did I know! Cathe blew away my gym instructor. I was hooked and have never looked back. Other than a couple of hiatuses due to some minor surgeries, I have pretty much done Cathe workouts every single week for the last 18 years and I'm still not bored. I mix Cathe with running, and they are a perfect complement to each other.
