Contraindications
Flexion-intolerant low back pain — regress to crunches.Setup
Anchor a band behind you at about head height while lying down. Lie on your back, knees bent, feet flat, holding the band ends at the chest or overhead.
Execution
- 1Brace the core before curling up against the band
- 2Curl the spine up segment by segment, pulling against the band resistance
- 3Continue up to a full sitting position with control
- 4Pause briefly at the top
- 5Lower back down under control, resisting the band's pull
Key cues
- Curl up like rolling up a mat
- Fight the band the whole way, both directions
- Exhale hard on the way up
- Control the descent, don't collapse
Common faults
- Using momentum instead of controlled curling
- Band too heavy, causing poor form
- Anchoring feet too aggressively, letting hip flexors dominate
- Rushing the eccentric phase
Tweaks
- Adjust band tension for difficulty
- Combine with a twist at the top for an oblique emphasis
- Progress to weighted sit-ups once comfortable
