- Seat pad can be locked in place or unlocked for pivoting movement
- Pivoting seat pad provides multiple abdominal exercises and results in greater activation of the core musculature
- Starts the body in an upright posture with the exercise handles overhead to pre-stretch the abdominal muscles
- Rocking movement lowers the hips to increase the involvement of the abdominal muscles to produce trunk flexion
- Designed to offer constant lumbar, thoracic and cervical support to avoid hyperextension or unnatural loading of the spine
- Avoids the excessive hip flexion unlike traditional ab machines
