Arm Exerciser - Adjustable 22-440lbs Hydraulic Power/Arm Exercise Equipment/Upper Body Exercise/Chest Workout/Shoulder Exercise Machine

[ Adjustable Resistance ] The torsion arm trainer can easily adjust strength by turning the resistance button, allowing you to customize exercise intensity according to your fitness level. Stepless adjustment gradually increases resistance, strengthens self strength training, and helps you enhance arm strength. The hydraulic powered fitness equipment is made of high-density thickened double carbon steel and hydraulic cylinders, and has undergone multiple durability tests to ensure that the structure will not deform or break during long-term training, which is superior to traditional spring powered torsion bars. The core of the fully enclosed hydraulic cylinder is a fully sealed hydraulic cylinder that can maintain stable force. Simple structure, reliable operation, and adjustable resistance. When adjusting resistance, the fixed arm angle and motion trajectory provide stable resistance that does not weaken over time. Our arm exercise equipment features a unique golden ratio triangle structure, which provides greater weight-bearing capacity and more stable exercise. It is more effective for arm/chest exercises and biceps/shoulder exercises. Easy to use and store: The bottom of the hydraulic torsion arm exercise device is made of ergonomic PU handle, which is wear-resistant, anti slip, and comfortable to grip. There is a buckle at the bottom of the handle for easy storage and carrying. After exercising, please rotate the adjustment knob to the lowest level and lock the handle with the buckle. The locked strength training device will occupy a small space. When removing the buckle, please hold the handle with both hands to prevent the handle from being bounced.
