Place two sturdy elevated platforms like weight plates or push-up handles slightly wider than shoulder-width on the floor. Assume a high plank position with hands on platforms, body straight from head to heels, arms extended, core braced.

1. Bend elbows to lower chest below hand level between platforms, keeping elbows at 45 degrees to torso.
2. Maintain straight body line with core and glutes engaged.
3. Lower until chest nears floor or mobility limit.
4. Pause briefly at bottom if desired.
5. Push through palms to extend arms explosively back to start.
6. Squeeze shoulder blades at top.
7. Repeat for reps.
