Keeping fit is not only about being free from illness but also about having a strong body and a good mood. Here are some useful ways to keep fit. First, a balanced diet is the foundation of good health. We should eat more fresh vegetables and fruit, which are rich in vitamins. We should also have some whole grains and protein, like rice, fish and eggs. At the same time, we must avoid eating too much junk food and drinking soft drinks, as they are bad for our body. Second, regular exercise is necessary. We can do sports like running, swimming or playing basketball for 30 minutes every day. Exercise helps us build a strong body and relax our mind. Third, we need to get enough sleep. Going to bed early and waking up early is a good habit. We should sleep at least 8 hours a night, because enough sleep gives us energy for the next day. 1 学科网（北京）股份有限公司 $
