I like to train heavy, but I really see only competitive lifters using chalk. Can it benefit me as a bodybuilder? And, if so, on which lifts?
Chalk has the same basic advantage as straps: A better grip. Serious powerlifters use it all the time, but it does not offer the same benefit as the straps – it does not “lighten the load” in the same way, but it does make your grip less of a limiting factor. The difference is that the chalk’s main function is to simple to keep your hands dry. If you have ever had a serious deadlifting day, you know you can work up a mean sweat and the last thing you want is the barbell slipping from your hands at a crucial part of the lift. This can result in injury. If you are at a gym that allows chalk, use it. If not, then straps may be a better alternative. Best alternative? Wipe your hands dry and pull the weight raw.
