OstroVit Chalk Block 57 g

OstroVit Chalk Block is nothing more than magnesia in a cube. A product that will improve your grip. All you need to do is grind the required amount into smaller portions and rub your hands with it to significantly improve your grip during heavy training on poles, handrails or in the gym. This form of pressed magnesia does not splash, which is its great advantage.

Remember that the further use of magnesia during training should be adapted to your individual preferences, hand sweat and weather conditions, the most important of which are temperature and humidity.

Recommended use

Crush the required amount into smaller portions and rub in your hands.
