Keep a good grip on your barbell and other gym equipment with REP’s Gym Chalk. This chalk is made from magnesium carbonate, a solid, inorganic mineral that is uniquely insoluble in water. In that, it absorbs moisture (like sweat) on your hands, so the bar won’t slip out of your grip.
In addition to weightlifting, you can also use Gym Chalk for calisthenics, gymnastics, rock climbing, and more. Each package of Gym Chalk comes with eight 2oz blocks -- enough to last for months of daily use.
