Attach two heavy bands to a high anchor point. Facing toward the anchor point, get into your Base Stance and grip the handles with the palms facing away from the anchor point. Add an appropriate amount of tension in the bands and begin the exercise with your arms extended straight down to your sides. Perform the exercise by reaching back with one foot and bending that knee until it reaches the floor, then drive the same knee toward the anchor point until the upper leg is parallel to the floor. Then, return to the starting position. Alternate legs, then repeat cycle.
