A STRONG CORE FOR ANY BODY
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.
Optimize your resistance level. Set resistance at the precise level best for you and your goals.
Don’t wait for the next ten pounds. Continually challenge muscles with frequent, small increases in resistance.
Ideal when training for speed and power. Small increments are an important tool when training fast with lower resistance.
Perfect for rehab and reconditioning. One-pound increments and a starting resistance of zero help find the right resistance level to recover from injury or a deconditioned state.
