Attach the harness around your waist or over your shoulders.
Facing away from the sled, make sure there is tension in the rope attached to the sled.
Assume a strong athletic stance: knees flexed, hips back, core is brace, chest is up and shoulders back.
Slowly walk forward, keeping tension on the rope at all times. Drive through the ball of your foot to pull the sled. Keep your neck in a neutral position.
Maintain postural integrity throughout the exercise. Never slumping or crouching. KEEP THE CORE TIGHT!
