Straddle hollow body hold
Abs

- On your back.
- Engage your abs so that your upper back lifts off the ground.
- Keep both legs straight, open, and lifted off the ground.
- Extend your arms while protracting your scapulae, so that your upper back is rounded.
- For perfect technique, check that you have no lumbar curvature and that your scapulae are protracted, while simultaneously contracting your back muscles to depress them.
