Why choose the A300 Runner?
Lower risk of injury. Pain-free range of motion.
The A300 Runner 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. The goal is to maximize your workout with fewer reps, so you spend less time working out and more time living.
