100% Original Design Since 1997
Because Great Design Makes Great Machines.
01 Dynamic Weighting
Experience smooth and effective workouts with our meticulously designed cams. They ensure consistent muscle tension from the start, eliminating any “no-tension” moments.
02 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.
03 Effortless Adjustments
Experience seamless customization with our intuitive adjustment systems. For instance, when you adjust the back pad on our benches, the seat automatically aligns for the perfect training posture. Unlike many brands that use cumbersome pin systems, our designs prioritize ease and efficiency.

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.
61A Racing Series
01 Made for Today. Tested by Time.
The 61A Racing Series is our most popular line — created to match real-world gym needs with practical, lasting design.
02 Built to Last
We chose every part with durability in mind:
– 75×118×3.0 mm semi-elliptical tubing for the main frame
– 50×120 / 40×80 / 50×100 mm flat oval pipes for functional areas
– Steel plates over 1 cm thick at high-stress points
– High-density foam seats, solid slide bars, and self-developed bearings, pulleys, and cams
Some machines from this series have been running for more than 20 years—and they’re still going strong.
03 Space-Saving and User-Friendly
The compact design helps gyms make the most of their floor space, while still fitting users of different sizes.
We fine-tuned every detail—pulley ratios, cable slack, movement angles — to make sure each machine feels smooth and natural to use.
Since the 61A Racing Series is our top seller, it’s been improved again and again based on real feedback from users around the world.
What you get today is a mature, well-tested design.
04 60+ Models, Full Coverage
With 62 machines in the series, the 61A Racing line meets nearly every strength training need — from single-joint machines to full-body systems.
We’ve been in the industry for over 30 years. When you buy from us, you get more than just equipment.
We’ll be here whenever you need help—now and years from now.
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.
