Liveup Massage Bar LS-5054

When using the ab roller, your core moves to prevent your back from arching, while flexing the spine to both stretch and contract your abs through a full range of motion. This movement provides a huge challenge to your rectus abdominus, the six pack muscle, as well as deep spinal stabilizers, such as the transerve abdominus. This makes the ab wheel roller a great tool for both a stronger, and more muscular core.
