Hollow Body Hold
According to Danielle Barry, a CrossFit level 2-certified coach at Solace New York, hollow body holds are "the king of building core stability and strength."
- Begin on your back with your legs straight and your arms extended overhead.
- Actively press your lower back into the floor, and draw your belly button into your spine.
- Inhale to slowly lift your shoulders, arms, and legs off the floor. Keep your hands and heels as low to the ground as possible, while still pressing your lower back into the floor. Maintain tight abs and glutes. It's OK to bend your knees if straight legs are too challenging.
