MGN56 HMS is 100% magnesium carbonate or, in other words, a chalk.
Magnesia prevents hands from sweating and increases friction, assuring a stronger and more secure grip. To be used in the gym where sweaty hands can cause a risk of an injury. Thanks to it, when using dumbbells or a barbell we do not have to worry about possible slippery equipment.
MGN56 is a chalk in form of a cube. Application is very simple, just rub the cube on your hands. Advantage of the cube over the powder is that it does not dirty the equipment around it so much.
It is also used in gymnastics, climbing and any sport where a firm, strong grip is essential.
