Sodium is a great mineral that helps to regulate overall balance of vitamins and minerals present in your body. It is a very common misconception that sodium directly leads to bloating. Sodium should be controlled not cut out. Especially when you are low on carbs, as it is responsible for muscle fullness and strong muscle contractions. Being low on carbs stops your muscles drawing fluid into the muscles, and you need sodium to help you keep hydrated. Going too long without it eventually leads to dehydration. Sodium does make you hold water, but when you are training for a contest, doing cardio, tanning and posing, you are losing an enormous amount of sodium in your sweat and urine. This should be replaced through dietary sodium or you will experience cramping, weakness and low blood pressure. Sodium is only your enemy about 24-36 hours away from your show.
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.
