I feel effin beat up from the combination of chest day and jiu-jitsu yesterday. Got my ass seriously handed to me last night.
This morning: cardio, 100 (assisted) pull-ups/chins, stretching, and 100 arm-bar drills (really an abs exercise).
Back is at about 85% today. There's still something "off" low in the back/hips, though. I think my sacrum may be a little rotated or something. If it's still feeling like that at the end of the week, a trip to the doc's will definitely be in order.
