Cleans and Squats Workout

2 Rounds - 5 minutes each round(2 minute break between rounds)
Every minute on the minute:

3 Power Cleans
15 Air Squats


1st round I did all 5 minutes with some rest time between each set. I used 75#. During the 2 minute rest between rounds my quads were starting to tighten up pretty good...I tried to increase my weight to 85# but couldn't ever get it. I managed to get 80# cleans a few times but the second round I didn't get any full sets during the minute (never even got to the squats...there was a lot of failing going on). Also, I am about 85% sure that I will have a giant bruise on my sternum tomorrow.
