Test: Split jerk landing. Torso straight up and down stacked neatly under an anchored ribcage?
Mob: 1) Spend 3 minutes exploring each hip. Can you hold relax there? Use that PNF!
2) 4 min working on arm flexion (overhead) and thoracic (rib cage region of spine)
extension on the balls.
Retest: Split jerk. Bonus: Does your kipping pullup feel better too?
