ARX · Fort Worth

You guessed the weight last time. The machine does not have to.

Motorized adaptive resistance that matches the load to the force you are producing at every angle, and hands you a number instead of a guess.

Common patterns

Sound
familiar?

These are the patterns ARX at WLF is built around.

A fixed weight is only ever correct at one point in a lift. The rest of the set happens under what you could produce.

I have been lifting the same weight for about a year.

I do not actually know if I am getting stronger.

Twenty minutes is what I have, most days.

I stopped because I was not sure my form was safe on my own.

The pattern

A fixed weight is only correct at one point in the lift.

Your leverage and your strength change a lot between the bottom of a lift and the top, and the plate does not change with them. Most people only meet their real limit at the weakest point in the range. Everywhere else, the set is happening under what they could actually produce.

How ARX works here

Push. It pushes back exactly as hard.

The setup

The machine is set to you, not the other way round.

A coach sets your position and the range the movement will run through before anything is loaded, because adaptive resistance only means something if it is meeting you where you actually move.

The set

The resistance is whatever you produce.

The motor is computer controlled and adjusts continuously to the force you apply, so the load matches your output through the whole range instead of only at the weakest point. There is no plate to guess at and no spotter needed, because the system can only ever push back as hard as you push into it.

The record

Every set produces a force curve.

The screen records exactly how much force you produced and where in the range you produced it. That readout, rather than the weight you chose, becomes the actual record of the session, so the next one is compared against something real.

The rhythm

Short and concentrated, not a long circuit.

Because resistance meets your output through the whole range, a working set reaches genuine effort faster than it does under a fixed weight. An ARX session here is built around a small number of machines rather than a long circuit, which is designed to fit the kind of schedule most people actually have.

Questions

Asked before the first visit.

Anything else, call (817) 349-7815 and ask. A person answers, not a phone tree.

Do I need to know how to lift to use ARX?

No. There is no weight to select and no bar to balance, and a coach sets your position and range before anything is loaded. The resistance can only match what you put into it.

How long is a session?

About twenty minutes. Because the resistance meets your output through the whole range, a working set gets to real effort faster than it does under a fixed weight, so the session is built around a few machines rather than a long circuit.

How often should I do it?

A few times a week is the usual rhythm. Your coach will give you a specific answer built around what else you are doing, not a blanket number.

Is it safe if I have an old injury?

Tell us about it first. The system can only push back as hard as you push into it, which is part of why it suits people working around something, but that is a conversation with a coach and not a promise from a machine.

Does ARX replace the rest of my training?

It is one tool. At WLF it sits inside performance training alongside coaching and the rest of the floor, and what you actually need gets decided from your assessment.

Ways to start

The first visit is an assessment, not a package.

A coach sets you up, you run a working set, and you leave with a number to compare the next one against.
