Set-up: Take a light resistance band and place both feet inside of it while holding on with your hands. Now switch the grips of your hands so the band crosses in front and forms the appearance of an X. Hold and stretch the bands in front of you at mid-torso height.
Movement: Simply step your right leg out and, when in contacts the ground, bring your left leg back to shoulder width. Continue for desired reps and repeat on the other side.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
