Feeray Twister Arm Trainer for Men, 66-110 LBS Adjustable Chest Workout Equipment, Home Fitness Spring Resistance, Black/Blue

The Feeray Adjustable U-Shape Arm Trainer is engineered to support progressive upper body strength training without the clutter of multiple dumbbells or machines. By utilizing a secure mechanical pin system, users can manually adjust the spring tension between 66, 88, and 110 lbs to match their specific fitness levels. Unlike traditional straight bending bars, the U-shaped structural design allows for multi-directional compression, effectively isolating and activating the pectorals, deltoids, and arms simultaneously for a highly efficient, space-saving home workout. Important Safety & Usage Instructions: High-tension spring equipment requires proper handling to ensure a safe workout experience. Before each workout session, inspect the structural nuts and bolts to ensure the frame is completely secure. Always maintain a firm, full grip on the non-slip foam handles during exercises. Never release the handles suddenly while the spring is under tension, as this can cause an uncontrolled tension release. To prevent muscle strain, beginners are encouraged to start at the 66 LBS setting and gradually increase the resistance as strength builds.
