I definitely needed X Stretch this morning. Enjoyed it, too.
For whatever reason, I'm significantly more sore this week than I was during my very first week of P90X. My glutes and hamstrings have been uncomfortably tight for days, and my lower back isn't feeling great, either. Either the past five weeks of hardcore exercise is finally catching up to me, or the new workouts in Phase 2 are getting more intense. Regardless, this "muscle confusion" thing must be working, because my muscles have no fucking idea what's going on.
