Keiser A250 Seated Leg Extension Machine - Maximum Quad Power

The perfect match to the A250 Leg Curl. The quadriceps are one of the most powerful muscle groups we have and are responsible for much of our stability and mobility. This Leg Extension features a seat that adjusts forward and back without changing its tilt, for maximum comfort during the exercise. It is also available with an optional adjustable range limiting device (Model 1122) that can set the starting and ending points in the range of motion.

Keiser’s Dynamic Variable Resistance is designed to provide a smooth consistent Variable Resistance force curve at any training speed. Each machine has its own unique Variable Resistance curve designed and tuned perfectly for the muscles being used in that particular exercise. For users, this means that working out any speed, you’ll always be training at maximum efficiency.

Pneumatic Resistance

Keiser equipment is air powered (pneumatic), meaning lighter, quieter equipment in your facility. Compressed air for Keiser equipment is delivered through Keiser’s custom designed air supply system. Keiser strength equipment weighs less and is quieter than iron-based machines.

Power Display
The Power Display provides both resistance information and repetitions performed in clear 1 inch numbers. The two window displays measure in either one pound or one kilogram increments for single station units and 1/10 pound or 1/10 of a kilogram increments for the infinity series. All displays come with the Keiser eChip system standard. The eChip system is a simple to use electronic workout card that recalls previous workouts and settings and downloads the data easily into a personal computer without wiring or equipment.
