Effects of Pre-Workout and Hydration on Muscle Pump

Pre-workout or salt intake during training may not have a significant effect on muscle pump unless there is a severe deficiency of salt and fluids. The body rehydrates slowly, and the pump is actually derived from the water moving through various bodily systems. Doubling carbohydrate intake can potentially enhance muscle pump the next day. However, pre-workout products do not work effectively to enhance muscle pump and are not directly linked to muscle growth.
