Understanding the benefits of exercise.
1 But what exactly are its health benefits? To start with, physical activity increases the efficiency (效率) of your heart and lungs. During exercise, your heart and lungs must work harder. This extra effort makes them grow stronger over the long term. It has also been proven that active people tend to have better immune systems and are at lower risk of diseases. Moreover, exercise is good for your mental health. Working out can help you reduce stress and get over bad feelings. Some studies even show that exercise improves certain brain functions, meaning you could actually exercise your way to better performance at school.

When you plan an exercise routine, ①the first thing to consider is what you expect to improve: heart and lung efficiency, muscle strength or flexibility, which involves aerobic (有氧的) activities, strength training, and flexibility training. These types of exercises all play a role in a healthy routine. Above all, choose activities you enjoy. ② 3
Eating and drinking right.
To help your muscles recover and repair themselves after exercise, you need to eat foods rich in protein (蛋白质). ③When to eat is also of great importance. Generally speaking, you should have your meal an average of 1.5 to 2.5 hours before exercising. Do not eat immediately after exercise. 4 Remember to drink throughout exercise to make up for water lost to sweat.
