Query: The Yoga sucks.

You need to be fit to use this program and pass the fitness test. The P90x Yoga is 1 1/2 hours long. Take small breaks and it's 2 hours long. I did so many up-dogs that I lost count and hurt my back in the process. I was out of work for 3 days. I never touched p90x after that. Find a program that is shorter and easier on the spine!
