Place your left hand on your stomach, directly over your belly button.
Place your right hand underneath your head.
Take a breath and let your stomach expand.
Exhale and draw your abs flat to your spine as you simultaneously tuck your chin toward your chest. Think about nodding "yes." Avoid bulging your abs forward and keep your shoulder blades on the ground throughout the entire movement.
This completes one rep.
With every rep, be sure to bring your abs toward your spine and contract your pelvic floor (think about "pulling" it toward your head). Then, relax your abs and pelvic floor as you take a diaphragmatic breath (a deep breath from your diaphragm).
Inhale and return to the starting position.
Perform slow and controlled reps for one minute with your left hand over your belly button, then switch and repeat with your right hand over your belly button.
If you have pain in your neck or shoulders when you lift your head, keep it on the ground.
