Optimize your workout with the Twister Arm Trainer thanks to its flexibly adjustable resistance, ranging from 22 to 440 lbs and adjustable in 20 levels via a dial. This is ideal for strengthening your upper arm, back, triceps, shoulder, and chest muscles.

This strength training machine utilizes a micro-rebound mechanism that minimizes the risk of violent rebounds, ensuring safe use for smooth and controlled strength training.

The arm exercise machine features a robust cast steel and high-strength plastic frame, along with a durable hydraulic cylinder that has successfully passed over 100,000 load tests, guaranteeing consistent resistance.

Equipped with a non-slip TPR rubber grip, this Twister Arm Trainer ensures a comfortable hold and secure, stable handling thanks to its triangular design.

To operate the safety buckle, grasp the handles with both hands and unlock the buckle with your thumb. To close after training, bring the handles together again with both hands and lock them with the buckle.
