Movement: Pack your shoulder blades together and tight, and brace your core placing your hands flat on the ground at shoulder width. Setting the handles of the suspension trainer very close to the floor, carefully place your feet inside them. Stay braced and do not allow your lumbar spine to extend or the hips to sag or flare up. Brace through the core and maintain proper posture throughout - a straight line should form intersecting your feet, hips and shoulders.
Emphasis: Do not allow the hips the sag, or the butt to flare up above the back. Keep the shoulder blades back and together. It may be helpful to visualize proper standing posture - the posture here is the same, only your body is rotated 90 degrees toward the floor.
