Hollow Rock

Hollow Rock

Description

The hollow rock is a foundational gymnastics core exercise where you hold a hollow body position (slightly rounded back, ribs down, legs and arms extended) and rock back and forth like a rocking chair. It builds tremendous anterior core strength and is the foundation for many advanced gymnastics skills.

Hollow Rock Instructions

  1. Lie on your back. Press your lower back firmly into the floor.
  2. Lift your shoulders, arms, head, and legs slightly off the floor.
  3. Reach your arms overhead alongside your ears. Keep your legs straight and pointed.
  4. Round your upper back slightly. Pull your ribs down toward your hips. This is the hollow position — your body forms a gentle banana shape.
  5. Brace your core hard. Maintain this position rigidly throughout the rocking.
  6. Begin gently rocking back and forth like a rocking chair, using a slight upper-body lift to drive the rock.
  7. Keep the hollow shape constant — the entire body moves as one unit. Do not break the position.
  8. Continue for 20 to 60 seconds. If you cannot maintain the hollow shape, regress to the hollow hold first.
