Spirit SP-3503 Back Extension
Price on request
Sold by: Spirit Fitness
Product details
A loaded back-extension station most gyms lack
The lower back is easy to neglect and expensive to injure, and most gyms only offer a bench for it. The Spirit SP-3503 Back Extension gives members a selectorised, adjustable station, so the posterior chain gets trained properly under controlled load.
Who it's for
Commercial gyms, physiotherapy and rehab centres, and studios that want a dedicated back-extension station.
Key benefits
A roller pad self-adjusts for ideal positioning across the upper back, reducing setup fuss. An adjustable range of motion fits each user's capabilities and preferences, which suits rehab as well as general training. A foot bar allows lower-body stabilisation during the exercise, and built-in top storage holds a phone and water. A 110 kg stack with 7.5 lb increments supports progression.
