Adaptive resistance exercise with ARX is what allows us to provide you with the most effective workout of your life in as little as 20 minutes a week.

ARX technology combines computer-controlled, motorized resistance that is capable of matching the force of any user 100% of the time. This gives you the perfect rep, every rep. With perfect resistance, ARX shortens the time you need to exercise while dramatically increasing the safety and effectiveness of all of your workouts.

It is the first technology created that perfectly accommodates any user’s force output and measure it repeatably and accurately throughout the entire range of motion. Throw in some tracking software for motivation, while quantifying all of the important metrics, and you have ARX - the next generation in exercise equipment!

Instead of using weights as a means of resistance, ARX uses finely-tuned motors to provide what is called “adaptive resistance;” resistance applied to the user only in response to their own effort. Physical effort against resistance is the first step or “active ingredient” in all exercise, and its downstream effects give us all the health benefits we know and love from training.

ARX provides safe, controlled, immediate, infinite, and quantifiable resistance that is of a higher quality than is currently possible with the out-dated, gravity-based systems found in gyms worldwide.


It sounds completely fake, right? Get stronger and healthier in one or two 10-20 minute sessions a week? Like, really? Seriously? That sounds like some cheap magazine gimmick.

The answer is yes, really. You can’t understand until you try it out though, so….

No gimmicks, no tricks. Just precise, quantifiable fitness. We can PROVE to you that it works.

What is ARX? How does it work?

ARX is resistance training technology that uses computer-controlled, motorized resistance in place of weights or other more traditional forms of resistance.  This “adaptive resistance” provides safe, controlled, and quantifiable resistance that is of a higher quality than is currently possible with weights or other gravity-based systems found in the world today.

What makes it so great?

ARX meets you where you’re at in terms of effort. It will push against you what you put against it, which is a constantly varying force. By doing this we can reach the precise % of muscle failure we want, without any guess work. Therefore we can get precise results, without any speculation about what weight to use or speed to move at.

Why does it take only 10-20 minutes?

Due to the adaptive resistance and speed controlled reps, there’s no need to do any complex rep scheme, you reach desired muscular failure within one set of each movement.

How do you set the resistance on ARX?

There is no need to set the resistance on ARX, since it is computer controlled and mechanized, it will meet the force you put against it, and no more.

Is it safe for post-rehabilitation exercise?

ARX is safe for all forms of rehabilitation, offering the full spectrum of resistance ranging from passive resistance (stretching) all the way to eccentric loading (negatives). There are no weights to drop, the speed is manageable and controlled, and the machine can never act upon the user. This means that a user can never encounter any forces that they themselves did not first produce, and this never-excessive scenario dramatically lowers the risk of injury

How often should I train on ARX?

ARX can be used once per week, seven days per week, once per month, or anywhere in between depending on your goals. In the same way that the metal weights in a gym can be used in a wide variety of ways, ARX technology can be used in various rep/set schemes, varieties, intensities, and more.

With ARX, any protocol is possible and no matter which you choose, ARX will provide you with the safest, most efficient, and most effective form of resistance you can find today.

Can ARX add muscle mass?

The body’s adaptive response of building stronger, bigger muscles is provoked primarily by the following three things at the muscular level:  mechanical tension, physical damage, or accumulation of the metabolic byproducts of fatigue.

These stimuli can all be produced using weights, but with access to ARX’s adaptive resistance, you can produce all three elements in greater magnitudes, more safely, and more quickly than with any weight. So for those looking for a pump, bigger muscles, or just looking to build a more aesthetic physique, ARX is the best tool currently available to achieve all of these outcomes.

Will ARX bulk me up?

Not unless that is your specific goal. ARX can be optimized for any goal by programming the level of muscle strain, speed of the reps and time under tension, just like any other type of weight training.
