Super Back Extension
$2,295.00

Multi Angle Strength Systems

The M.A.S.S. Super Back Extension is the safest and most effective way to perform the Back Extension exercise.

The ADJUSTABLE ANGLES range from a “warmup” at 55 degrees to a very challenging 27 degrees.

The angled THIGH PADS adjust up and down to allow trainers of all heights to be comfortable.

The HAMSTRINGS PADS are adjustable in height and distance to the trainer, securing the user safely with their knees slightly bent, providing outstanding isolation on the GLUTES and LOWER BACK.

The unit also offers many LEG and BACK STRETCHING options using the 5 lower handles.

The stainless steel adjustment section features a GAS-ASSIST CYLINDER to make changing the angle easy.

The multiple foot plates feature an anti-skid surface.

The front hand grips and rear wheels make it easy to move within your facility.
