Achieving Quality Resistance

Quality of resistance is the primary determinant of strength training effectiveness. Due to changes in user strength throughout exercises, consistent quality resistance has been impossible to achieve: Until now.

Let's look at the problem. Throughout each exercise, user strength varies in important ways:

Strength Curve: Each person's unique musculoskeletal system leads to strength variations from position to position in each exercise.

Positive/Negative Strength Variance: The average person starts out 20-50% stronger during the negative (lowering) phase of an exercise than the positive (lifting) phase.

Fatigue: Strength decreases from the start to end of an exercise due to natural fatigue. During this time, positive strength is reduced faster than negative strength.

Conventional gravity based exercise systems attempt to compensate for these strength changes through cam and lever systems or basic motors. While this may work for some strength variations, no conventional exercise machines have been able to match resistance throughout the strength curve, positive/negative exercise cycles and user fatigue. Most of these systems offer too few strength setting increments to fit a range of user physiques, and improper counterbalances.

The problem? Conventional systems offer low-quality resistance and inefficient exercise.

The ARX Fit Solution

ARX Fit solves the strength variation problem, combining motorized resistance with a smart computer system. Its motorized resistance perfectly matches the user’s changing strength over the full range of motion in both the positive and negative phases of every repetition for the full duration of the exercise.: We call this adaptive resistance exercise.

ARX Fit accommodates users of any strength level, from the least to the most strong. It provides each user with the exact level of resistance they require on every exercise for perfect progression. It can actually assist less strong users in performing exercises they would be incapable of on their own through passive resistance or stretching.

Receive maximum metabolic and cardiovascular conditioning with this ultra-efficient system. Perform multiple exercises from a single seated position or quickly switch to bench or platform movements. Minimize rest times, and cut your exercise time by as much as two thirds.

Safety

The ARX Fit was engineered with user safety in mind:

Nothing to Drop
The ARX Fit system's highly responsive controls allow the user to instantly and smoothly stop and unload at any point during the exercise with no fear of a movement arm or weight crashing down on them. There are no plates to drop or weight stacks for fingers to get caught in.

Smooth Turnarounds
Reverse direction smoothly — without the sudden jerky or jarring change of direction occurring in some motorized machines.

Easy Entry and Exit
ARX Fit was designed for easy entry and exit — with seats at a comfortable height for even shorter users. They present minimum risk of tripping or collision when getting on or off.

Neutral Position of the Head and Neck
The commercial model's large, 20″ touch-screen monitor is positioned where it can be easily seen by the user with the head and neck in a safe, neutral position.

Encourages Proper Form
Competitor machines feature poor start-and-stop engineering, which encourages bad form. ARX Fit moves at the user-selected speed regardless of user movement. The smooth transitions offered by our computerized system promotes better form and better results allowing the user’s muscles to optimally work through safe, controlled, and effective contractions.
