Today, instead of doing a round of P90X Yoga, I decided to do something different.
That "something different" was the Insanity Fit Test, and In 30 minutes it pretty much wiped the floor with me. Holy mother of God...and it was JUST the Fit Test!
My heart rate was in the 150-160 range the whole time, which was good. I'm glad I didn't try to do it before I had started P90X, or it probably would have killed me, haha.
