Fitness first and then swimming, because fitness is a warm-up exercise, swimming is equivalent to relaxing the whole body underwater. Just eat one or two eggs a day. If you eat too much of this egg, it will not be fully absorbed by your body. Avoid eating too much egg yolk, which is high in cholesterol and has a bad effect on your body. So one or two is best. It can not only supplement the needs of the body, but also cause no adverse effects. Exercise mainly consumes water and sugar, which has little to do with how many eggs you eat.
