73 Tough Series
01 Engineered with Purpose. Built to Perform.
“The 73 Series reflects everything I understand about strength equipment.”
By George Yang | Founder and chief designer at YR Fitness

02 A Head Start in Innovation
The 73 Series was the world’s first line of pin-loaded machines with natural, independent, converging and diverging movements.
Its design was completed in 2006 and officially launched in 2008—six years earlier than Life Fitness’ Insignia series.

03 Engineered Tubing That Sets Us Apart
We used special elliptical tubing:
– 75×130×3.0 mm for the weight stack column
– 58×101×3.0 mm for the movement area
The frame follows a clean, parabolic flow that still stands out today.
No other brand uses this tubing or shape.
The machines are finished with a large number of aluminum alloy accents and custom-cast aluminum parts, adding both strength and a premium look.

04 Built from the Ground Up
Designing this series was not easy.
It took our team 1 full month just to figure out the cable routing layout.
We also developed many components from scratch, including:
– Pulleys
– Cams
– Bearings
– Multi-directional handle joints
Why? Because only self-developed parts could meet our strength and performance standards.

05 Hand-Assembled with Care
Due to the curved design and special frame structure, mass production is difficult.
Most of the 73 Series are hand-assembled, piece by piece.
If you’re looking for professional-quality equipment with real attention to movement and structure, the 73 Tough Series is a solid choice.

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.
