DESIGNED By ATHLETES,
FOR ATHLETES
At YR Fitness, Design Transcends Aesthetics.
It’s About Functionality.
Simple, But Significant.
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.
