Crap.

Warmup:
1 min. each of:
Rowing
Pushups
Situps
Pullups
Squats

Workout:
75 lb push jerk, 10-9-10-9-10 reps
10 25" box jumps after each set

During my last set, I upped it to 32" box jumps, just for fun. On my 7th jump, I failed, and upon catching myself, my lower back went apeshit. It seems muscular, but it freaking hurts. Thank god for all the crossfitters who helped me get my pants and coat on, get into Ferrari's car, and thanks to Ferrari for getting me home. So...hopefully I can walk tomorrow, otherwise I don't know how I'm getting to work. Crap.
