Drive heels into the floor, bridge hips up and push shoulders to back of their sockets. Slide both hands underneath your lower back with hands towards the floor.  Slowly lower hips towards floor and low back into hands. Contract and relax as well as oscillate in and out of end range tension. DO NOT roll shoulders forward. Keep shoulder externally rotated at all times.  If your shoulders roll forward, stop stretch and start over from the beginning.   Calf Work:  Calf elongation on plate, bonesaw, or barbell calf smash.  Lots of jumping, so make sure to take care of those calves pre-wod and post-wod.
