Stand on the sled platform with your back facing the sled and your shoulders positioned against the pads. Place your feet about shoulder-width apart on the platform and keep your chest upright with your core braced. Lower your body by bending your knees and hips, allowing the sled to travel as you descend into a controlled squat. Go down until your thighs reach at least parallel while maintaining knee alignment over your toes. Push through your heels to extend your legs and return to the starting position without locking out your knees. Repeat for the desired reps with steady, controlled movement throughout.
