Why Adaptive Resistance

Get the perfect rep--every time!

Adaptive Resistance™ exercise dynamically adjusts your resistance in real-time to provide you with exactly the right amount of resistance you can handle on every rep of every set.

What Is Adaptive Resistance?

Our breakthrough Adaptive Resistance™ technology uses patented, motorized resistance and computer software to give you the perfect workout every time.

Each repetition is perfectly matched, in both the push and pull motion, during your workout so that you receive the exact right amount of resistance automatically at every moment of your workout.

Achieve The Perfect Rep

When a you experience Adaptive Resistance, your muscles are challenged on both the positive and negative portion of every rep to the exact level you are capable of at each moment.

Compared to traditional tools like weights, these optimal levels of resistance allow for improvements in strength, muscle mass, bone mineral density, and cardiovascular fitness to occur in just minutes per week compared to hours per week.

Use The Best To Be Your Best

ARX’s revolutionary technology has been quantifiably improving the lives of tens of thousands of people around the world for a decade.

From athletes and celebrities to busy professionals and parents, these high-performers use ARX so they can look, feel, and perform at their best.

ARX vs weights

ARX Is More Effective and Efficient Than Weights

2.5xMore Fat Loss

When it comes to losing fat, burning glycogen in your muscle tissue is essential. During an ARX workout, a lot of glycogen (sugar) is burned during the positive portion of a repetition.

The more force your muscles have to produce, the more glycogen your muscles use. When the body burns large amounts of glycogen, your insulin sensitivity increases, your blood sugar levels lower, and both of these have a direct impact on if your body stores any excess glycogen that is not already in the muscle as fat or not.

In a recent study, the ARX group lost 2.5 times the amount of fat compared to the Weight Lifting group over the course of 12 weeks.

2xMuscle Mass Gains

In order to develop new muscle mass, your body must first be exposed to a form of stress that signals to the body the need to develop this new muscle.  

The most useful form of stress signal for developing muscle comes from performing resistance exercise and the quality of the signal depends on the quality of the resistance.

ARX provides the highest-quality resistance available by perfectly loading your muscles during every moment of every set.

When you have perfect, adaptive resistance, you can optimize the stress signals required to develop muscle mass.

In a recent study, the ARX Group gained approximately 2 times the amount of lean mass compared to the Weight Lifting Group over the course of 12 weeks.

3.5xGreater Cardiovascular Fitness

The cardiovascular system’s primary function is to pump blood and oxygen to your body's muscles. When your muscles have to produce a lot of force, they need a lot of this blood and oxygen, causing the cardiovascular system to work hard to keep up with this demand.

When you use ARX,  you expose your muscles to very high, but very safe levels of force, the muscles must handle this force which will cause the cardiovascular system to also increase its capacity to match the demand on your muscles.

In short, this means that when you perform high-intensity resistance exercise on ARX, the end-result is that both your muscles and your cardiovascular system will need to improve to handle this new level of demand.

In a recent study, the ARX Group achieved approximately 3.5 times the cardiovascular performance improvement of the Weight Lifting Group over the course of 12 weeks.

90%Greater Strength Gains

In order to increase a muscle's strength, you need to expose that muscle to high levels of mechanical tension (stress) in the form of resistance exercise.

The greater the mechanical tension, the greater the strength improvements, generally.

Since ARX’s Adaptive Resistance can provide you with higher (but safe) levels of mechanical tension on your muscles, your therefore receive superior strength improvements using ARX than most other traditional tools.

In a recent study, the ARX Group achieved 90% greater strength increases than the Weight Lifting Group over the course of 12 weeks.

72%More Time Efficient

Using traditional tools like weights, the official recommendation is for you to spend approximately two hours per week performing resistance exercise.

If you wanted to reduce this weekly time commitment, you would need a more effective form of resistance exercise.

ARX’s Adaptive Resistance provides optimal resistance during every moment of every repetition, making it one of, if not the, most effective forms of resistance exercise in existence.

In a recent study, despite spending 72% less time exercising, the ARX Group still achieved 2.5 times greater fat loss, 2 times greater muscle mass gain, 3.5 times greater cardiovascular fitness improvement, and 90% greater strength gains than the Weight Lifting Group over the course of 12 weeks.

The Research And Science Of Adaptive Resistance™

The following reports are from an independent study that was performed by the
Physiology Program at Western Colorado University:

ACE – Certified™: How Adaptive Training Compares To Traditional Resistance Training

Adaptive resistance exercise equipment uses artificial intelligence to create workouts that are safe, controlled and use quantifiable resistance, but how do these workouts compare to free weights or traditional resistance-training machines?

Researchers in the High Altitude Exercise Physiology Program at Western Colorado University set out to find out the answer.

Adaptive Resistance Training Is Superior To Traditional Resistance Exercise

Featured in the International Journal Of Research In Exercise Physiology, this randomized, controlled study was designed to compare muscular fitness, anthropometric, and cardiorespiratory fitness outcomes between Adaptive Resistance (ARX) and traditional moderate-intensity resistance exercise with weights.

"I'm 51 years old and my number one priority in life is to live as long and healthy of a life as I can and exercise is critical to making that happen. Owning the ARX in my home has been really convenient and in just one month, I put on 7 pounds of muscle mass using the ARX!"

"We only need 100 clients to make our business model work and we actually broke even on our ARX investment in the first month. If you look at ARX's "revenue per square foot," you're not going to find a better business model out there in the fitness space."
