Grant said this exercise activates the transverse abdominis muscle and the pelvic floor, which are both important for stability of the spine.
- Start on your hands and knees with your spine in a flat, neutral position. Allow your tummy to relax. Imagine a zipper running from your tailbone, through your legs, along your bump, and ending at your chest.
- Inhale to prepare, and as you exhale, imagine zipping yourself up. You should feel your glutes and abs engage, and your bump rise up slightly.
- Inhale to release. This counts as one rep.
- Repeat for 12 to 14 reps.
