- On the floor, face up.
- Contract your abs so that your upper back lifts off the ground.
- Bend your legs, bringing your knees to your chest.
- Extend them again to complete one repetition.
- With respect to technique, extend your arms while protracting your shoulder blades, 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 engaging your back muscles to depress them.
