1, before exercising, don't eat too much and don't drink too much liquid.

2. When exercising, the best drink is mineral water, not a sports drink (it is designed for athletes, and the average person's exercise is not in place, so it is unnecessary).

3, drink a cup of yogurt or milk after fitness, do not eat supper, do not eat staple food.

For those who lose weight, eat more vegetables when exercising, and for those who have long muscles, eat more meat, especially beef.
