Stand on a band; try attaching to a rig, if possible. Start hopping with two feet and feel the band assisting you to pull your feet up from the ground. Next, using muscle elasticity, keep your knees bent and feel your feet pull up in response to touching down on the ground. Then run in place, and feel the same “up” feeling as you pull. You will feel this in your run as long as you stay in position and fall.
