HOW: Start in a standing position with a slider underneath one foot. Hold onto a dowel with the hand opposite side to the foot with the slider. Begin to slide back while keeping your knee straight. Load the other leg’s heel, push into the ground and slide your leg back up into the starting position once you go back as far as you can.
FEEL: You should feel your hamstring muscles working in the leg that stays stationary.
COMPENSATION: Hinge forward at the hips as you slide your leg back, don’t slouch.
