Balance your core. Strengthen your spine. Build true body control.

The Hollow Hold Challenge alternates daily between hollow holds and superman stretch holds - two powerful movements that target your core and back for complete midline strength. One day you stabilize from the front, the next you support from the back - creating perfect balance, endurance, and resilience over 30 days.

✓ Hollow holds for deep core strength
✓ Superman holds for back and spinal support
✓ Alternating structure for balanced development
✓ Minimal time, maximum body control

Stronger every hold.
Stronger every day.
