How to Master the Fold

- Start Position: Lie flat on your back. Press your lower back into the mat. Extend arms overhead with palms facing down.
- The Engagement: Exhale and pull your belly button toward your spine. Simultaneously lift your shoulders and legs.
- The Fold: Round your upper back into a “C” shape, reaching hands toward your feet until you form a “U” supported by your glutes.
- Control: Squeeze your abs at the top for one second, then slowly inhale and lower your body back to the start position.

⚠️ Avoid the Common Mistake: Do not keep your back flat. If you don’t curl your spine into a “C” shape, you miss the full abdominal shortening required for the “Fold” effect.
