Many athletes consume as little salt as possible before the competition, in order to reduce the moisture under the skin, so as not to affect the dehydration effect of bodybuilders. But in fact, at the same time, the water content of muscle is also decreasing. No matter how you warm up before going on stage, you can't reach the pumping feeling in normal training. This pumping feeling often appears in post-match training, and the muscle state is often better than when you are on the stage, and the blood vessels become more ferocious.
