Zontoo Adjustable Hand Gripper

Crush strength, dialed in. One gripper, adjustable from warm-up to “can't close it.” Counter on the handle so you don't have to keep score.

What it is

An adjustable-resistance hand gripper with a mechanical rep counter. Turn the dial for resistance, squeeze, count.

Spec

• Resistance range approx. 10–60 kg (22–132 lb)
• Non-slip textured handles

How it's used

1. Set the dial to a level you can close 10 times clean.
2. 3 sets each hand. Add a notch when 15 gets easy.
3. Pairs with the Finger Trainer Ball — one closes, one opens.
