Cathe is my first experience with fitness videos, other than yoga/pilates, and I'm completely hooked. I'm an experienced exerciser and gymster, although I stopped going to the gym a year or so ago after I set up my own home "gym" (a set of dumbells, a bench, stretch bands, heavy bag, etc). I found a gym is completely unnecessary -- all you need are some dumbells and your bodyweight. And I love my pullup bar! I play a lot of sports outside as well, so that's my cardio.
I like Cathe's workout philosophy, especially all the weight and strength work. My first dvd was Boot Camp/Muscle Endurance, which I think is fantastic. I like all the circuit training.
