What It Is / How It Works

This hand gripper is an aluminum alloy spring grip trainer. It uses a spring to provide resistance as you squeeze the handle closed, so you can build grip strength in the hands and fingers.

Who It's For / Use Cases

Hand gripper trainers suit adults who want a simple, repeatable way to build grip strength. They also suit people who want to progress gradually, starting with lighter resistance and moving to heavier settings as their hands get stronger over time.

How to Use / Care

1. Choose a poundage setting that matches your current training stage.
2. Hold the aluminium alloy handle in one hand and squeeze the spring closed.
3. Release slowly, then repeat for your planned number of repetitions.

How to Choose

Pick the poundage that matches your training stage. Lower settings suit an introduction to grip training, and higher settings suit more intensive training. Since the range runs from 100 to 300 pounds, you can move up as your grip gets stronger. The ergonomic shape and knurled surface help keep the grip comfortable and secure during each set.
