Using Magnesium Strategically Between Attempts

Bouldering chalk absorbs moisture from your hands and can be applied in varying amounts depending on its form. Loose powder, chalk balls, and liquid varieties differ primarily in how they’re applied. The key isn’t applying as much as possible to your skin, but choosing a type that suits your habits and the guidelines at the bouldering spot.

Distinguish Between Indoor and Outdoor Climbing Chalk

Check with the climbing gym to see which forms are allowed. A chalk ball releases powder through its shell, while loose chalk is taken directly from the bag. Liquid chalk is applied differently before each attempt; be sure to follow the product instructions. Also consider the packaging when comparing options. If you switch frequently between the gym and the rock, you’ll benefit from a solution that seals tightly and is easy to transport.

• Application: Do you want to apply magnesium before a climb or in between climbs?
• Rules: Is the chosen form permitted at your training location?
• Dosage: Is it easy to dispense the required amount?
• Organization: Do the contents and packaging fit in your bouldering bag?

Consider holds and the surrounding area

Keep chalk bags for bouldering and a suitable bouldering brush within easy reach. On Swiss boulders, follow local guidelines and use chalk sparingly. Magnesium doesn’t guarantee a better grip and isn’t a substitute for footwork. Explore chalk options for bouldering and compare the different forms based on how you train and organize your outings.
