Features

UNLOCK HAMSTRING POTENTIAL

The A400 Leg Curl Pro is designed to train the hamstrings at speed, enhancing neuromuscular control and reducing the risk of injury. With improved ergonomics, including a repositioned chest pad, thumb buttons, and display, it offers superior comfort and ease of use. Its unilateral design allows each leg to move independently, mimicking natural movement patterns—whether training symmetrically or in a cycling motion, where one leg lifts as the other lowers. The ability to incorporate eccentric overload further strengthens the hamstrings and aids in injury prevention. Integrated with Keiser’s advanced A400 technology, this machine tracks real-time performance metrics and seamlessly syncs with the Keiser Metrics App for data-driven training optimization.
