HOW: Keep constant outward tension on the band the entire time. Start in a ready squat position. If going to the left, take one step forward and to the left with your left leg. Then bring your right leg up back to the ready position. And now take one step back and to the left with your left leg. Then repeat with right.
FEEL: You should feel your glutes on FIRE the entire time!
COMPENSATION: Keep tension on the bands the entire time. Do not let your knees cave in.
