Workout Log for April 29: Crossfit WOD 21-15-9

I've put myself on a strict schedule leading up to my exams on June 2nd. This is the first day, and I'm following it reasonably well. Instead of worrying what to do for a workout, I'm just going to be following the Crossfit WOD at 10:00 a.m. whenever possible and do endurance work at 7:00 a.m.. I was supposed to do clean and jerks today, but my knees are crippled after DLs and V-squats yesterday, and my left forearm had trouble holding the bar, so I switched to box squats. Oh, and I didn't run. :P
21, 15, and 9 reps as giant set for time

1. Sumo DB deadlifts 100 lbs.
2. Box jumps
3. Bodyweight squats

That was enough for today. We'll ease into it.
