CTX is fabulous, intense, features 5 different cardio sections that you can do as is, or stick 2 back to back for extra sweat factor. It also features a tough leg workout (quick, mean and dirty!) and a very thorough upper body workout, and yes, an "all abs" choice. just because they are shorter, don't think they are not intense. Cathe gets the heart rate where she wants it very quickly and then keeps it there, there's no gradual build up to it as you have on, say, Powermax. It's "bang!" right in there.
What's not to love?
I never tire of it, it always seems fresh, the music is good, and I never regretted the cash I spent on it, ever.
