Magnesium Chalk Block is a practical magnesium cube, which you may also know as sports chalk or gym chalk. It serves to improve and strengthen the grip, thanks to which you will be able to enjoy proper, but at the same time safe training. Its leading feature is that it absorbs moisture perfectly and takes away the sweat, which creates friction between the fingers. In addition to being your faithful companion in heavyweight training, it will help you cope better with CrossFit, bouldering, climbing walls or mountains. You can buy the cube as one piece (56 g) or a package containing 8 pieces (8 x 56 g) of Chalk Block Magnesium.
