Lee Special September 15, 2014ExercisesSSD Description: 30-foot rope tied to a 40 or 60 pound sandbag. At the far end of the rope, get into a push up position facing the sandbag. While in the push up position, balance on your two feet and left hand, and make three pulls on the back toward you with your right hand. Then switch hands, and make three pulls with your left hand. Keep switching hands every 3x pulls or so until you pull the bag to you.
