We’re changing the way the world trains.
ARX was founded in 2011 with one goal: give everyone access to the safest, most effective, most efficient form of resistance exercise — by inventing Adaptive Resistance Exercise™.
Talk to ARXReal strength — without the weights, the guesswork, or the risk.
For decades, building strength meant heavy weights, real injury risk, and no way to know if it was working. We set out to fix all three. The result is Adaptive Resistance™ — patented, computer-controlled resistance that matches your exact force on every rep, captures force data on every rep, and delivers a complete full-body workout in about fifteen minutes. We invented it — and we still build the most effective version of it.
What training on ARX is actually like.
~15 minutes, full body
A complete, full-body workout in about fifteen minutes — on a footprint under 40 square feet.
Matched to you, every rep
The motor meets your exact force through the whole range — including the lowering phase weights can’t load — so you train as hard as you can without ever overloading a joint.
Measured, not guessed
Every rep is captured as force data, so you can see — and prove — that you’re getting stronger.
For operators, the model is simple: members typically pay $250–600+ per month, around 100 members is six-figure annual revenue, and there are no franchise fees or royalties — all in under 40 square feet. ARX for Business →
