I'm 47 and have been working out with Cathe for a couple of years...my first purchase was HiiT, which was an advanced workout getting great reviews on Collage. I had been doing "advanced " workout videos from other instructors and was getting so bored. Cathe showed me that I could do so much more and have so much fun in the process...I'll never go back! Thanks to Cathe, I lift heavier weights than I ever thought possible (and have wonderful muscle tone and strength) and am in the best cardiovascular shape of my life ( when I signed up at the gym last year, it came with a free fitness analysis...basically a way for them to show you where your fitness weaknesses are and how a trainer might be of help). They were pretty condescending when I told them my cardio was doing exercise videos at home, but they didn't have much to say when I tested at elite athlete level...hah...score one for Cathe (and, to be honest, I almost fainted from pleasure at the validation of all my hard efforts)!
