For the last three years, my wife had been solely exercising to tapes by Denise Austin. While I cannot tolerate her for long, my wife was losing weight and was happy doing so. Then, I saw Cathe on Discovery Health one day and was floored by the intensity. After tooling around this site, I bought Cardio Kicks and MIC. My wife and I have come to the conclusion that Cathe is a bad-ass....I mean that in a good way. I couldn't believe how much I was sweating the first time I did Cardio Kicks. These tapes were a definite upgrade to what we were using before. Cathe is the best video instructor I have ever seen (well....maybe next to Donna Richardson, but I digress). Thank you Cathe for making the best tapes I've ever seen and without the unnecessary "cheerleading". No bull, no garbage. Just the knowledge I am going to be wiped out when done. Cathe is just TOO SWEET!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
