Independent channels put the Go-Tone Pro through real training sessions, on their own gear, in their own words.
The Cable Machine. Reimagined For Serious Trainers.
Motor-controlled cable resistance in 1.5 lbs — with three programmable training modes built for people who've outgrown standard home workouts.
Controlled
Smooth, consistent resistance on every rep. The same feel as a commercial cable stack — in a device that fits in your bag.
Lbs
Door frame. Hotel rack. Garage. Park. 60 seconds from bag to first rep — wherever your day takes you.
New Modes
Speed Mode. Eccentric Overload. Progressive Resistance. Three protocols no other portable device can run.
/Month
All three modes. Full resistance range. Unlocked from day one. No app required. No monthly fee. Ever.
One Device.
Three Protocols.
Zero Monthly Fees.
The Go-Tone Pro is built for the trainer who wants more than constant load. Whether you're rebuilding after injury, breaking through a plateau, or chasing maximum muscle growth — the Pro has a mode engineered for exactly that. One purchase. Full ownership. The workout follows you.
Complete Full-Body Training
In One Compact Device
Gym-quality resistance for your entire body. Chest, back, shoulders, arms, legs and core, from a device that weighs 1.5 lbs. Digital resistance holds a smooth, adjustable load from 3 to 30 kg (66 lbs) through your full range of motion, and keeps the tension honest at every point of the rep.
Dial. Anchor. Lift.
Three steps from bag to first rep. No tools, no installation, no subscription required — and no one waiting on the cable machine.
Dial The Weight.
Press the buttons. Resistance updates instantly — up to 66 lbs on one device, or 132 lbs when you run two. No plates to swap, no pin to move, no interruption between sets.
Anchor It.
Loop the strap over any door, rack or fixed point and it wedges tight in seconds. No drilling, no wall mounts, no gym membership required.
Lift.
That’s the whole protocol. Constant, controlled cable tension from the first inch of the movement to the last — any exercise, any room, anywhere you take it.
Under 60 seconds.
The Gym That Fits
In Your Backpack.
The whole system weighs about as much as a full water bottle. Drop it in a bag, loop it over any door, and go from zipped-up to your first rep in under a minute — hotel room, office, garage, anywhere you land.
Busy week, hotel room, back at your parents’ place. The session happens anyway. That’s how strength compounds: not with perfect weeks, but with zero missed ones.
Real People. Real Strength. Real Life.
The people behind it
Built By Athletes.
Built For Real Life.
I'm Johnny, triathlete and endurance athlete. Long hours running, biking, and swimming left little room for the gym. And the gym never felt built for people like me, people with a sport, a schedule, and a life that doesn't pause for a 90-minute lifting session. So I built something that did.
At Rayofi, we believe time is the one thing you can't get back, so everything we build is designed to help you use it better. Rayofi exists to make serious training more flexible, more efficient, and more human. We're just getting started.
Feel every mode.
The motor rewrites the load mid-rep. Pick a mode — Speed, Eccentric Overload, or Progressive — then scrub the curl and feel the tension change in real time.
Introducing New Cooling System.
The new modes push harder. Eccentric Overload and Progressive resistance demand sustained motor output — and sustained output generates heat. The built-in fan keeps the motor at optimal temperature, so resistance stays accurate from your first rep to your last.
Resistance accuracy maintained throughout heavy protocols. No mid-session drop-off, no degraded tension as the motor heats up under sustained load.
Built for daily training, back-to-back sessions, and shared households — the volume that would push the original to its thermal limits.
Sustained optimal operating temperature extends motor precision over the lifetime of the device — not just the session.
Less heat variation means quieter sustained performance and the same resistance feel from set one to set ten.
Go-Tone Pro — Built-In Cooling System
Upgraded Internals.
Engineered To Last.
Every part that let the original down got re-engineered. Scroll to pull the Pro apart and see what changed inside.
The number-one first-gen complaint was units seizing up. Resistance now comes from a sealed, copper-wound motor — no belts, no gears, nothing that can jam or wear loose.
Heat was the old unit’s weak point on high settings. A dedicated internal fan and vented housing pull heat away from the motor so resistance stays steady, set after set.
A built-in rechargeable battery with USB-C and DC charging — no wall tether, no cords across the floor. Set it down and train anywhere in the house or on the road.
Resistance runs through flat retractable webbing rated far beyond max load — not a thin steel wire. No fraying, no kinks, nothing to snap, and it anchors flat to a door, rack or post.
Backed by a full 1-year warranty and a 60-day home trial. If it ever fails, we replace it — that’s the whole policy.

The Smarter Way
To Get Strong.
Not against other gadgets — against the ways you've already tried. Here's where the Go-Tone Pro wins, and where it honestly doesn't.
Go-Tone Pro
|
Smart Cable Gyms | Gym Membership | Resistance Bands | |
|---|---|---|---|---|
| Cost | One payment, yours forever | €2,000+ up front | €500+ every year | Cheap up front |
| Tension through the rep | Motor-controlled, first degree to last | Motor-controlled too | Cable machines only — if free | Only near full stretch |
| Eccentric overload & modes | 3 programmable protocols | On flagship models | Needs a training partner | Physically impossible |
| Know your exact load | Digital display, 1.5 lb steps | Digital display | Labeled plates | Guesswork |
| Time to first rep | 60 seconds, any door | Fast — but home only | Commute, changing, waiting | Fast |
| Heavy enough to grow | Up to 66 lbs per device | 100+ lbs | Unlimited | Stacking gets unstable |
| Fits in a bag | 1.5 lbs, hand-sized | Bolted to a wall | You go to it | Yes |

The honest verdict: a gym still wins on raw maximum load, and smart cable gyms deliver similar tech — at six times the price, bolted to one wall. For cost, consistency, controlled tension and actually showing up, the Go-Tone Pro stands alone.
The Gym You'll Actually Use.
Rated 4.5 on Trustpilot. Real cable training, real results — no subscriptions, no monthly fees.
Better Than My Commercial Gym's Cable Machine
"I was just going to use it for travel, but I use it all the time at home. I like it better than commercial cross functional trainers. It is very smooth. The 66lbs of resistance is plenty — I have not found an exercise where it is not enough.
Bought a Second One. That Says Everything.
"Amazing little machine — truly a portable gym. The concentric and eccentric resistances are tremendous. Love it so much I purchased a second one. Total gym under 8lbs with all accessories.
I Recommend This to Every Single One of My Clients
"I'm a personal trainer and was looking for a portable device. I think I found the perfect device. More than enough resistance. You can feel the eccentric phase — not easy if you do it the right way. I highly recommend it.
No subscriptions or hidden costs. Rayofi's cable gym is a steal in the world of home gym equipment.
