The popularity of online fitness increased greatly. Downloads of fitness apps quickly went up in number. New styles of exercises have appeared that people can do at home. Even though people exercise separately (分别地), they often do it together through the Internet. Online fitness allows people to exercise at anytime and anywhere without going to a gym or a fitness center.

According to a report from Douyin, the number of fitness videos in 2021 increased by 134 percent, while followers of fitness trainers went up by 208 percent compared with the year before. People often search online for simple exercises that are posted by personal trainers. These trainers do a great job in both teaching and leading people to exercise more.

In the past, TV exercise programs were popular, but now online fitness videos have made exercising even more popular because they are easy to learn. Even famous athletes are joining in. Some of them started online fitness courses to teach people how to exercise at home, and now they are very popular with many people.

A report from Jingdong in 2022 showed that sales of yoga and dance products have grown rapidly since March. Sales of yoga stretchers (拉伸器) and yoga bags increased by over 800 percent. The Chinese government has also organized online competitions on social media platforms (网络社交媒体平台). Ding Dong, an official with China’s General Administration of Sports, said, “The games are designed to encourage more people to take part in fitness activities.”

A lot of people play sports, but very few people become sports professionals (专家). If sports aren’t going to be your future, then why should you play them? Why should you train every day? Why should you work hard and feel sore (酸痛的) the next day? Wouldn’t it be better to forget sports and only pay attention to your lessons? In fact, there are a lot of reasons to play sports.

First of all, sports are a great way to exercise. Exercising keeps you healthy and strong. It also helps you stay in a good condition. When you exercise, your body makes endorphins (安多芬) which give you more energy and make you feel happier.

Also, sports teach young people how to communicate and work as a team. They teach young people to respect (尊重) their coaches, teammates and players from the other team. Many reports say that sports help young people stay out of trouble. If a young person plays sports, he or she may have fewer problems. This is because sports teach people about rules. They also teach people that if they work hard, they might succeed.

Another good way of sports is that they make people leave their houses. These days, a lot of people spend too much time watching television and playing video games. When you play sports, you go outside and exercise in the sun. You take in fresh air. All of these things are important.

Maybe you’re not going to become a sports professional, but that doesn’t matter, sports will help you become a better and happier person.
