C4 Revival Series
01 Where Performance Meets Style
The C4 Revival Series is a fusion of everything we’ve learned from our most trusted lines.
Visually, it builds on the clean, compact look of the 61A Racing Series.
Functionally, it levels up from the advanced biomechanics of the 73 Tough Series.
C4 is our next-generation lineup — combining proven design with fresh innovation.
02 Strong Inside and Out
C4 is built for serious, long-term use.
– 150×50×3.0 mm flat oval tubing forms the main frame
– 50×120 / 40×80 / 50×100 mm pipes are used in the movement areas
– All stress points use plates no thinner than 1 cm
– High-density foam seats, solid slide bars, and in-house developed bearings, pulleys, and cams keep the machines smooth and durable
03 Designed to Look Good Too
C4 brings a fresh visual style that fits modern gyms perfectly.
Its sleek look and clean lines make the training space feel younger and more dynamic — perfect for attracting today’s fitness crowd.
04 More Movement Options
The C4 Revival Series doesn’t just look better — it also offers more functional upgrades:
– Independent arm movements
– Adjustable elbow pads
– Multi-directional rotating handles
– Adjustable back support for chest and shoulder trainers
– Specialized machines like biceps/triceps isolators that are rarely seen in the market
These small but smart features give users more control and better comfort during workouts.
05 Still Growing
We’re continuing to add exclusive C4 models that address niche training needs and user preferences.
This is a living series — one that evolves with fitness.
Only True Feedback Counts
Quality Standard of YR Fitness
That’s why we are confident to compete with big brand quality, but at 1/5 price.
Built with Strength: 3.0mm Solid Steel Pipes
We use thick 3.0mm+ Q235 steel pipes for every part of the machine — whether it’s the frame or the training area, no matter the size. With added reinforcement bends, our machines stay strong and steady. No shaking, just solid power.
This is How We Make Your Gym Equipment
Over 20 years, YR Fitness has put $8M into tech—just to bring you better machines.
100% Original Design Since 1997
Because Great Design Makes Great Machines.
Pulley Output Ratio
Leveraging the power of physics, we’ve tailored our pulley output ratio for optimal training. Take our butterfly machines: a 2:1 ratio means a 70kg weight selection delivers a 35kg training load. This higher ratio enhances your workout and saves on weight plate costs.

Let’s Talk
Blake Fisher
Gym Owner from Malaysia
Our members love using this. Super strong with top engineering. Great quality at an affordable price. Smooth to operate, can handle big weights and hits the target muscle. We are very satisfied for these gym machines! We plan on opening another gym once the virus is over.
Jay Dang
Gym Owner from Australia
Commercial quality. Well made. I feel it is just as good as the other top brand benches we have at our club eg Technogym, Matrix etc, but is so much more affordable. All of my order arrived on time and the sales manager was awesome to communicate with. Highly recommend!!!
