*Use your time wisely. Warm up with enough sets so when you get to your working sets it's not a shocker. Make small-medium jumps in weight to get to your working sets. The sets of "1" are progressive, meaning, you will try to increase the weight each rep, and possibly set a new 1RM PR for the clean. Rest at least 2 minutes between your working sets. These cleans will be Full Squat Cleans.
***Challenge*** if there's time left:
Your mission, should you choose to accept it...
Handstand hold for 1 full minute. :-)
