Lie on your side with your arms and your legs extended. Bring your feet slightly in front of you so you're in a hollow position.
While keeping your navel pulled into your spine, simultaneously lift your arm(s) and legs a few inches toward the ceiling. Engage your core as you hold this position for five seconds before lowering back down.
Shown here are two options for holding your side hollow hold. You can put one hand down for support — like the side hollow pulses — or you can lift from your core without putting a hand down.
