Product details
A 45-degree station for the muscles gyms train badly
The posterior chain is easy to neglect and costly to injure. The Spirit SP-4220 Back Extension sets a fixed 45-degree position that is ideal for training the posterior muscles, so members can work the lower back safely instead of improvising.
Who it's for
Commercial gyms, physiotherapy and rehab centres, clubs and home gyms that want a dedicated back-extension station.
Key benefits
The 45-degree position is ideal for training the posterior muscles with a consistent range of motion. Adjustable thigh pads fit all user sizes, and lower leg pads support at the calf to eliminate knee discomfort during the movement.
