Back Extension
The Proformance Plus Back Extension by TuffStuff eliminates most of the compressive and shearing forces of traditional exercises that work the spinal erector muscles, allowing you to train them more safely and effectively. Squat and deadlift variations will be right at the top of the list for those who have the mobility required to perform them with proper form. For others, our build or injury history may preclude us from subjecting our spines to the heavy loads that squats and deadlifts require.

- Adjustable pivot arm with multiple start positions.
- Lumbar support prevents accidental overextension.
