If you're looking to exercise the wrists, arms, shoulders, chest, and back at the same time, the RELIANCER Adjustable Hydraulic Power Twister is perfect for you to develop your grip and strengthen your upper body. 

The unique golden ratio triangle structure with 10 reinforcement rivets makes the arm trainer load-bearing capacity, always keeping it in a stable state.

The RELIANCER is a hydraulic arm exerciser made of high-density double carbon steel, engineered plastics, and a hydraulic cylinder, which passed 100,000 endurance tests, ensuring durability.

An ergonomically designed PU handle provides you with a comfortable grip and a special anti-slip texture design ensures safety. 

Unlike other forms of spring-based exercises, the RELIANCER Power Twister adopts a totally enclosed hydraulic cylinder which offers you stable resistance strength with a new twist, which will not weaken over time. 

The resistance strength can be adjusted by rotating the knob, from 22 to 440 pounds, and has 2 to 20 levels, ensuring as you get stronger you can increase the intensity level.

Whether your right arm is your dominant arm or your left arm, push the two handles in to get the resistance you desire with the RELIANCER Adjustable Hydraulic Power Twister!
