HmJ 5 This liquid chalk is fantastic and seems to be of good quality (no skin issue after months of use).Keep this in your gym bag and you'll be ready for exercises requesting stronger grips.There are accessories to relieve the grip, but it doesn't make your muscles stronger.The chalk however helps to keep comfortable grip while training the muscles to become stronger. Slowly but surely.Last point: liquid chalk is very useful and clean, and you will avoid to make your gym / clothes dirty and dusty.
