LISM Adjustable Hydraulic Arm Twister for Strength Training

Train your arms with adjustable resistance that lets you tailor each session, from lighter work to a challenging 440 lb setting.

• Adjustable intensity: Turn the knob to set resistance from 22 to 440 lbs, so you can change the effort as your workout progresses.
• Steady, comfortable grip: The triangular center structure and non-slip PU handles help you hold the trainer securely during arm exercises.
• Folds for storage: Use the rear buckle to fold and lock the trainer, making it easier to move and put away between sessions.
• Hydraulic design: A fully enclosed hydraulic cylinder and double-layer steel pipes support durability, while the micro-rebound system provides a controlled return motion.
