KEISER - A250 Lower Back


A250 Lower Back

MODEL 2821


Keiser’s A250 Lower Back differs from any of its competitors on the market. It focuses not only on building muscles, but also protecting them. Unlike conventional machines that use iron, the A250 Lower Back’s low‑inertia design gives you a smooth resistance. This can help protect joints and connective tissue from shock loading. The result is a safer workout. And it’s perfect for people at any fitness level — from older adults to elite athletes.
