I was going to give myself a break today. The P90x program says that today, which is day 7, I can either rest or do "Stretch x." I was going to rest, but then I started to feel guilty, so I did 30 minutes of Yoga. I feel much better.
Tomorrow, I start over with the P90x "chest and back" and "ab ripper x" DVDs. I'm already dreading it!
