Setup
- Sit on the front third of a sturdy chair or flat bench with your feet flat on the floor, hip-width apart.
- Place your hands behind your head with elbows wide or grip the sides of the seat for stability.
- Lengthen your spine and engage your core to stabilize your pelvis and lower back.
How to do it
- Inhale and lift your chest toward the ceiling, initiating a gentle arch in your upper and middle back.
- Exhale as you lean back over the backrest or into space, extending your spine while keeping your neck in line with the curve of your back.
- Hold the peak stretch for 2 seconds, focusing on the opening of the ribcage and the stretch in the abdominals.
- Inhale as you use your core and back muscles to return slowly to the upright starting position with a 2-second controlled tempo.
Form checklist
- Keep your feet firmly grounded to prevent the chair from tipping or sliding.
- Avoid 'crunching' the lower back; focus on creating an even arch throughout the entire spine.
- Keep your chin slightly tucked or neutral to avoid overextending the cervical spine.
- Maintain a slow, controlled tempo to ensure muscle engagement rather than relying on gravity.
Pro tips
- Think about lifting your sternum 'up and over' an imaginary bar behind your shoulder blades to maximize thoracic mobility.
- Squeeze your shoulder blades together slightly during the extension to further open the chest and engage the upper back muscles.
Make it harder
- Extend your arms straight overhead to increase the lever length and the demand on the core and erector spinae.
- Hold the end-range extension for 5-10 seconds to increase time under tension and improve flexibility.
