Swing to handstand on parallel bars

Good progress on swing handstands last night... Marcus and I stressed the forward push into the crab position after an upstart (Level 4 mount) followed by a "sink" (shoulder girdle elevation) in the shoulders as they swing BW to 45° - then WITH HEART OVER HANDS **click** (completely flex shoulders while flattening lower back) into an aligned handstand position... Center of Mass (or "heart") should be positioned above first knuckle NOT on the heels of the hands. Control is maintained using hands and wrists NOT elbows and shoulders. Those joints and everything above are stabilized.
