This is a DB Snatch Series I learned from Mike Burgener. I use it with my athletes at the beginning of a workout as a transition from warm up into the first major exercise. 6' 10" Ryan Pierson demonstrates it here. He performs 3 DB snatches (both arms), followed by one R arm snatch and a lunge with each leg, then one L arm snatch and lunge with each leg. He finishes with 3 snatches with both arms.
