Developing strong, fast, and powerful abs is essential for upper body performance, as the core serves as the direct base of support. The A400 Abdominal machine, built with Keiser’s innovative design and engineering, stands apart from traditional machines.

The result is a workout experience unlike anything else on the market. Integrated with Keiser’s advanced A400 technology, it tracks real-time performance metrics and seamlessly syncs with the Keiser Metrics App for data-driven training optimization. Perfect for all fitness levels—from older adults to elite athletes—the A400 Abdominal machine ensures a safe, effective, and efficient workout.
