OstroVit Magnesia in cubes 57 g
OstroVit Chalk Block is nothing but magnesia in the cube.
A product that will help you improve your grip. Just crush the necessary amount into smaller portions and rub your hands with it to significantly improve the grip during heavy training sessions on bars, parallel bars or the gym.
This form of compressed magnesia does not spray, which is its great advantage.


Magnesia cubes:
- provides better friction
- increases hand grip
- eliminates sweating during training
- dries the skin
Remember that subsequent applications of magnesia during training must be adapted to your individual preferences, hand sweating and weather conditions, of which temperature and air humidity play the most important role.
