【Adjustable Power Twister】This power twister allows you to easily adjust resistance by turning the knob (or "dial"), making it more user-friendly than traditional spring-based arm trainers. With adjustable resistance from 22–440 lbs (2–20 levels), it’s perfect for everyone—beginners, men, women, novices, and veterans alike. Simply rotate the knob to choose your ideal resistance level.

【Easy to Use and Store】

The ergonomic PU handle is wear-resistant, non-slip, and provides a comfortable grip. The handle features a quick-release buckle for easy storage. To assemble: Hold the handle with both hands, press the buckle with your index finger, and it’s ready to use.

【Strong and Sturdy Material】

Our hydraulic fitness equipment is built with high-density carbon steel, engineering-grade plastics, and a durable hydraulic cylinder, rigorously tested over 100,000 cycles to prevent deformation or breakage. The fully sealed hydraulic cylinder ensures simple operation, reliable resistance adjustment, and long-term safety. Unlike traditional devices, it maintains consistent resistance without weakening over time.

【Golden Ratio Triangle Structure】

The unique golden-ratio triangle design, reinforced with 10 rivets, enhances load-bearing capacity and stability for maximum safety. Ideal for targeting wrists, arms, shoulders, chest, and back, it helps improve grip strength, finger dexterity, and overall upper-body power—whether you’re a beginner or an advanced user.
