I guess I must be confused on the terminology too.

I've been calling my cardio 20-MAS for 20 minute areobic solution. Mostly I do fast walking/sprint intervals. When that's not possible I do an aerobics tape which has about 10 minutes warm up, 20 minutes areobics and 5 minutes cool down. Is there a name for what I'm doing other than being confused?

I also thought that HIIT was the wieght training - high intensity interval training, with the 12/10/8/6/12/12 sets

*LOL* guess it doesn't matter much what it's called. At least I'm doing it and I LOVE IT!
