Keiser Infinity Functional Trainer - Rehab & Performance Functional Trainer
Smooth Constant Resistance With Virtually Zero Shock Loading

Just because you can pull a cable in a variety of directions doesn’t make it functional. It’s pulling at the speed we perform that makes it truly functional. We designed this machine to be faster than the fastest human being, so we could properly train any movement, at any speed, in any direction. To truly understand what this all means, you’ve got to try it. Once you do, you will understand true FUNCTION. The Functional Trainer MUST be purchased with either a Free-Standing Base (Model 3025) or our Floor Mount Base Plate (Model 3021) or our Extended Base Plate (Model 300836) that raises the FT up 12 inches (305 mm) for basketball teams. (The Floor Mount and Extended Base Plates must be securely anchored to a concrete floor per instruction.).

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.
