I'm 27 and discovered Cathe on FitTV in 2006. When I first previewed her workouts on FitTV I thought, "this woman is nuts - there's no way I can do that." So I didn't. Fastforward to Summer 2010 and I decided to give Cathe another shot. I started with Imax 2 (yeah...wouldn't recommend that), Step Blast, and Kick, Punch, Crunch. I could barely survive doing the shortened versions from FitTV WITH commercial breaks! After a few months I started noticing changes in my body and endurance levels, realized Cathe knew what she was doing, started building my prized "Cathe Collection" and haven't looked back!
