OstroVit Chalk Powder – nothing but magnesia in a cube. A product that will improve your grip. It is enough to break the necessary amount into smaller portions and rub it on your hands to significantly improve the grip during heavy training sessions on bars, bars or gym. This form of pressed magnesia does not spray, which is its great advantage.
Remember that the subsequent applications of magnesia during training must be adapted to your individual preferences, hand sweating and weather conditions, the most important of which is temperature and air humidity.
