A250 Abdominal
Since the upper body’s direct base of support is the core, developing strong, fast and powerful abs are key for upper body performance. Keiser’s design and engineering set this machine apart. Unlike conventional machines that use iron, the A250 Abdominal’s low‑inertia design gives you a smooth resistance. This can help protect joints and connective tissue from shock loading. The result is a workout unlike anything else on the market. And it’s perfect for people at any fitness level — from older adults to elite athletes.
