Keiser A250 Lower Back Machine - Increase Your Back Strength
Everyone Needs A Strong Back!

Most people underestimate the value of a strong back and that is why so many people suffer from low back pain. Besides the low back muscles being heavily involved in all the lifting we do, the lower back also has to stabilize the pelvis when the very strong and powerful glutes and hamstrings are pulling on it. Keiser’s Lower Back may help reduce lower back pain in an otherwise healthy lower back and is why it should be an essential part to your Keiser line and workout.

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.
