Zontoo Chalk Block

Dry hands, honest grip. A block of magnesium carbonate. The oldest grip aid there is, and still the one that works.

What it is

A 2 oz block of pure magnesium carbonate gym chalk. No liquid, no fragrance, no batteries.

Spec

• Magnesium carbonate, 2 oz (56 g) block
• Individually wrapped

How it's used

1. Rub the block across the palm and fingers. Tap off the excess.
2. Re-chalk before the top set only.
3. Check your gym allows loose chalk. Many don't — keep it in a zip bag.
