Today, Athletes’ Performance, Peak Performance, Mike Boyle Strength and Conditioning, and LA Fitness are just a few of the big name facilities buying into the air-powered equipment. According to Keiser reps, sales of Keiser’s pneumatic cable pulley systems and racks have increased by 68 percent over the last three years.

There are mechanical and physiological changes occurring that determine how much force one can generate through an exercise’s range of motion.

Of course, power isn’t the only advantage to working with air.

Resistance on pneumatic machines is selected by the push of button, instead of by loading heavy plates or reaching down to adjust a pin in a weight stack (less ideal for older or injured trainees).

There is normative data for that comparison as well.

These numbers help when determining if it is safe to return to play or work after surgery or injury.
