BUILD IT STRONG, BUILD IT FAST
For those interested in powerful resistance, look no further. This machine uses Keiser’s innovative engineering to give up to 600 pounds of resistance. It’s great for elite‑level athletes and for eccentric overloading. Unlike conventional machines that use iron, the A300 Chest Press Pro’s low‑inertia design gives you a smooth resistance. This can help protect joints and connective tissue from shock loading. The result is a workout unlike anything else on the market.
Features you won’t find in conventional machines
Unilateral movement means each limb can be trained symmetrically.
Enhanced resistance up to 600 pounds.
Large digital display that shows resistance, sets, repetitions, and peak power.
Thumb buttons let you change resistance without changing position — even during exercise.
Fast, easy, and precise eccentric overloading.
Change resistance in increments as small as one pound.
Industry-leading lifespan and uptime for years of use.
Unique versatility; five ways to train instead of only one.
Fully adjustable to accommodate a wide range of users.
Why choose the A300 Chest Press Pro?
Lower risk of injury. Pain-free range of motion.
The A300 Chest Press Pro 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.
