So why these two?
When swinging a kettlebell the hips must be mobile and the shoulders must be stable, packed down by the lats. Then the steel mace 360 flips this, with shoulders now mobile pushing and pulling the mace out and around as the hips remain stable. Both, however, ask the core for a lot of stability, but in different tied fashions. This is what Dr. Mark Cheng (creator of Prehab-Rehab) calls, the “Four Knots:” finding the right amount of stability and mobility in the shoulders and hips. He states, “If your shoelaces are too tight, you can’t move your feet well. If they are too loose, your shoe can come off. The knot must be a balance of strength and mobility.” Watch
