Gravity Shift is what happens when the floor decides to renegotiate the rules and your core has to step in as the mediator. The workout keeps returning to push-ups (your “baseline reality”) while throwing in plank rotations that try to twist you off-axis like a spaceship doing an emergency roll. Every rep asks your shoulders to stay packed, your ribs to stay down, and your midline to hold the line so the rotation comes from control, not collapse. It’s simple, but it feels like physics with attitude.

Then come the side-plank holds, the moment where gravity stops being a background setting and becomes the main villain. Those 10-count freezes train the obliques and deep stabilizers to keep you stacked, shoulder over wrist, hips lifted, spine long, like you’re bracing on the outside of a hull while the world spins. The “2+” push-ups make it scalable and spicy: do what you can with clean form, then come back stronger next set. By the end, you’ll feel welded together in the best way, steadier, tougher, and harder to knock off balance.
