CrossFit WOD: Squat cleans and burpees

Since my shoulder is still acting up a bit, I decided to some leg exercising - this killer WOD helped. It called for kettlebell swings instead of squat cleans, but I can't go overhead just yet w/o some pain. Waiting for the inflammation to go down. It's as follows:

In reps of:
21-18-15-12-9-6-3

Squat cleans
Burpees

I used 115lbs for the squat cleans. This workout killed me! I got 17 minutes flat.  I rested WAY too much but I had to. Squats destroy me, esp squat clean! Enjoy!

Best,
Tyler
