Attach dual handles to a sled using a rope or chain and load the sled with an appropriate weight.
Stand facing the sled, holding a handle in each hand, and back up until there is tension in the line.
Position your feet shoulder-width apart, bend your knees slightly, and keep your head and chest up with your arms fully extended.
Initiate the movement by retracting your shoulder blades and flexing your elbows to pull the sled towards you.
As the sled moves closer, take a step or two back to maintain tension in the line and repeat the pulling motion.
