○ Stimulation: In order to ride a bike healthily, people who don't do much exercise give their muscles a certain load of stimulation, resulting in increased muscles. Sports enthusiasts or professional drivers should not only ride bicycles every day, but also do various physical exercises to strengthen their muscles.
If you practice with much more strength than usual, muscle fibers will be damaged, and muscles will be sore when the damage is serious. At this time, the body will instinctively repair the injured muscles and repair them stronger than before. This phenomenon is called "super recovery".
○ Supplementing nutrients such as protein: Muscle needs energy and amino acids during "super recovery" (protein is composed of amino acids). Although you exercise hard, you can't increase your muscle mass without enough nutrition. Never be partial to food and eat all kinds of food.
○ Rest: You must rest after strenuous exercise. Growth hormone is not produced during exercise, but during sleep. Muscle is stimulated, and the stimulation is transmitted to the brain, and the brain will think, "You may need to use muscle today, so you should gain muscle." In the evening, growth hormone begins to play a role and increase muscles. People often say that "sleeping a baby will gain weight quickly" is the truth.
Muscle gain requires the above three factors, all of which are indispensable. You can't just focus on exercise and ignore nutrition and rest.
