Product details
Loaded lower-back training members can trust
The lower back is easy to neglect and expensive to injure. The Spirit SP-4310 Back Extension gives it a dedicated, loaded station, with an adjustable roller pad and dual foot bars so members train the movement safely through a full range.
Who it's for
Commercial gyms, physiotherapy and rehab-oriented centres, and studios that want a stable, purpose-built back-extension station.
Key benefits
The adjustable roller pad sets ideal positioning across the upper back for each user. Dual foot bars stabilise the lower body during the movement. A lower back pad provides stability while allowing a full range of motion. A 128 kg stack, integrated rep counter and top-cap storage complete a station built for daily use.
