The hamstring muscles are one of the most neglected muscle groups. To address this, Keiser designed the A250 Seated Leg Curl to have a less intimidating seated position and to reduce stress on the lower back. An adjustable cushion holds the thighs in a comfortable and stable position for maximum results. An optional range‑limiting device (Model 1222) lets you set the starting and ending points in the range of motion.

Why choose the A250 Seated Leg Curl?
Lower risk of injury. Pain-free range of motion.
The A250 Seated Leg Curl reduces resistance where you’re most vulnerable to injury. And the low inertia of our resistance system eliminates shock loading; sparing your joints and connective tissues from harmful forces.
Achieve your training goals faster
Our machines increase resistance where you’re stronger and decrease resistance where you’re weaker. This allows your muscles to work at their full potential through every point in the range of motion.
Keiser’s machines focus on efficiency.
