I'm on my second week of doing PH three times a week. I was doing it twice a week for the previous 5 wks. You're right -- it is exhausting! Plus, I've done it so many times, it's difficult to keep my enthusiasm up. But I'll try. One more week of PH times 3, and I'm taking a week's break from exercise -- the first since early July.
As far as cardio tapes go, I like to mix 'em up. However, I am planning on doing Cardio Kicks tomorrow morning (be still my beating heart).
