Pure Resistance Technology™
Low-inertia design makes it more versatile.
The Infinity A300 Functional Trainer offers unmatched versatility to train any movement at any speed.
“Others build their machines like tanks. We build ours like aircraft — strong, but very light.”
DENNIS KEISER
CEO, Keiser Corporation
We remove any mass we don’t need.
We engineer the linkages between you and the resistance to have as little mass as possible. With less mass, there’s less inertia and momentum.
A more versatile alternative to iron
We use compressed air under digital control instead of iron resistance. It has almost no mass, inertia, or momentum. No matter how fast you move, you can’t throw it and you don’t have to slow it.
Dynamic Functional Resistance™
Infinity Functional Trainers are designed with a flat resistance curve. Resistance remains at a constant level, no matter your speed or direction.
Real-world speed. Real Functional power.
Keiser’s Pure Resistance Technology™ provides the smooth, consistent resistance that lets you train effectively at real-world speed. It's a better way to develop the power to perform in sport and life.
Develop true functional power. Power combines strength with speed. It's what gets things done. You can't call it functional if you can't move at real-world speed.
Move at real-world speed. Pure Resistance Technology™ eliminates the inertia from iron. This lets you get an effective workout at any speed.
Train explosive movements. With Infinity, you can train muscles to generate explosive power. Use high-intensity movements under load at speed to get the burst of power you need, when you need it.
Try our equipment. We’ll bring it to you.
Develop optimal power with Precise resistance.
With increments as precise as one-tenth of a pound or kilogram, you can find the perfect resistance level.
Set resistance with precision. Set your resistance level in increments as small as one-tenth of a pound — starting as low as zero. And do it with push-button accuracy.
Optimize your resistance level. With too much resistance, you move too slowly. And too little won't challenge your muscles enough. Infinity lets you set the exact resistance for optimal power and performance.
Use consistent resistance. Unlike iron, the A300 Functional Trainer gives you a consistent level of resistance — no matter how fast you accelerate.
EXTRA-LONG CABLE FOR GREATER VERSATILITY
With 140” of cable, when using one handle or 70” when using both, you’re free to unleash new training opportunities.
144 Different Position
Combinations.
Train for almost any movement with 12 independent positions per arm for a combined total of 144 different combinations.
Guided Tour
Explore the Infinity Functional Trainer.
Discover how easy it is to take advantage of the unique versatility of the Infinity Functional Trainer.
Reduce collateral damage with almost zero shock loading.
Iron's inertia can cause repeated stress on your joints and connective tissue. Our Pure Resistance Technology™ eliminates that. So, your training is less likely to cause injury.
Avoid repeated shock loading. Unlike iron, the low inertia of Keiser’s pure resistance means virtually none of the sudden excess forces you feel from iron.
Protect your joints. With almost no shock loading, you can avoid much of the risk to joints and connective tissue over time.
Enjoy a pain-free range of motion without the shock loading of iron. Get all of the benefits of functional training with significantly less pain.
