Set-up: Adjust the seat so the handles are at shoulder height and sit with your back flat against the pad. Grip the handles with palms facing forward.
Lift: Bracing through your core, push the grips overhead, just shy of locking your elbows at the top. Return to the start position under control.
Emphasis: Keep your core and back strong while maintaining natural spine position. Your core and back should work to stabilize the movement. Do not use momentum to complete the lift.
