HAND OVER HAND SLED PULL
Load a Prowler or another kind of sled and secure a long rope to one end. Extend the rope along the ground and stand at the end with your feet spread wide, core braced. Pull the sled toward you with the rope, using a continuous hand-over-hand motion. When it reaches your toes, walk the rope out to the end and repeat that process until you’ve traveled 50 feet.
“Really use that twisting of your torso to gain ground — reach forward as far as you can and pull the rope to your hip.”
