THE EASIEST WAY TO IMPROVE YOUR GRIP!

The device will give your forearms a good pump and will definitely make your veins pop! Using the gadget will strengthen your forearms and hands! The key to seeing results is consistency. Stick with it for a few weeks and you will definitely make progress.

WHO SHOULD USE IT?

The gadget is suitable for all ages and is particularly useful for:

  • Athletes: perfect for athletes participating in any of the following sports; basketball, baseball, football, wrestling, climbing, tennis, golf, and many more!

  • Musicians: an excellent tool for warming up your fingers when playing guitar, piano, and violin, to name just a few.

  • Anyone undergoing physical therapy: the device can help treat arthritis, carpal tunnel, strokes, and tendon surgery.

HOW LONG SHOULD YOU USE IT?

We recommend 15 to 20 minutes a day. 5 sets of 10 with 30 seconds of rest between each set is more than enough. Use a weight that you are comfortable with, but that still challenges you. If your forearms are sore, take a day or two off to allow them to recover. Be consistent and you will see results!

HOW TO USE THE GRIPSTER:

  • Step 1: Attach it around your wrist.

  • Step 2: Choose your weight setting.

  • Step 3: Place your finger in the groove of the ring.

  • Step 4: Extend your fingers and squeeze your fist at the end of the movement
