Hang Squat Cleans (155/105 lbs)
Coaches Note: In this workout you'll complete 75 Double Unders then 15 Hang Squat Cleans - 60 Double Unders and 12 Hang Squat Cleans etc. With a weightlifting movement like the Hang Squat lean following larger sets of double unders, breathing correctly to maintain a rigid spine and core during the squat is imperative. Consider using the valsalva technique:
When standing all the way up, before the clean, take a deep breath and squeeze your abs. Now lower the bar to the hang position and do the squat clean while maintaining that pressure or slightly letting a little air out like water forcing it's way out out of capped sprinkler. Stand all the way back up. Breath out.
The valsalva breathing technique can be extremely helpful in all weightlifting movements. If it doesn't feel natural, keep practicing it. It will and you'll reap the benefits.
