4 . Do you like to keep fit? We’re always told that regular exercise is good for our body and mind. More and more people are taking up activities that improve their fitness. But is there a risk that some of us might get obsessed (着迷的) and overdo it?

Well, for some people, fitness has become an obsession as they aim for perfection. And fitness trackers and apps can add to this addiction, especially if someone is driven by achievement and perfectionism. And sharing data on social media means exercising becomes public and competitive, which could cause problems in someone who is vulnerable (脆弱的). Experts say this can lead to a medical condition called orthorexia nervosa, or addiction to healthy eating and over-exercise. Untreated, it can lead to malnutrition and mental health problems.

Too much exercise can also take its toll on someone’s physical health as well. Symptoms of over-exercising include injuries such as a broken leg and a low immune system. So how much exercise is too much? Researches found the ideal pace to jog was about eight kilometers per hour-and that it was best to jog no more than three times a week or for 2.5 hours in total, showing that moderate jogging is possibly more beneficial than being inactive or undertaking strenuous (剧烈的) jogging.

If you’re more of a couch potato than a runner, this might sound like good news. But for amateur (业余的) athletes who can’t help but push their bodies to the limit, the advice from Martin Turner, a sports and exercise psychologist, is, “It’s all about letting go, not being obsessed, learning not to control everything, saying, ‘You don’t need to be perfect.’”

I’m really glad that you asked about sports in my school,

7 . The first time I realized that I had a love for sports competitions was during the Field Day in elementary school. Small for my age, and more of a bookworm than a sports enthusiast, I had suffered that special humiliation of being picked last for various gym teams. The Field Day, which focused on individual skills, was different. In the Softball Throw event, I got my first taste of sporting victory. Credit goes to the example of my first coach, my father. He lifted weights every morning at home. He bought us all baseball gloves and hats, and in the warm months, we spent hours playing catch. Come fall, our backyard football games began with passing practice.

Once I got to sixth grade and switched to private school, our entire student body was assigned to either the Red or the White team. Throughout the year, we competed against each other in various games and exercises for points. I eventually became president of The Committee of Games, accelerating (加速) my competitive fever. However, in girls’ sports games at my school, I was no star. I also played on the field hockey team and the basketball team. School sports did not bleed into the weekends, as they do today, but at home, playing tennis, skating, skiing and biking were simply normal things we did. During break time, magazines were also quite popular for us teens. These regularly featured articles on physical exercise. Somehow, my college roommate and I took up the habit of completing Royal Canadian Air Force (RCAF) exercises every day, a practice that continued into my marriage, when we had no spare funds to use to join a gym.

So, though it shocks some of our friends, that early foundation evolved in adulthood into a sports and fitness focus, considered essential even on vacation. I still love reading and the arts, too. As far as I’m concerned, life is the richest with my feet in both worlds.

People believe climbing can do well to health. Where can you learn the skill of climbing then? If you think you had to go to the mountains to learn climbing, you are wrong. Many people are learning what to climb in city gyms. To climb, you need special shoe and a safety belt around your chest hold you. A beginner’s climb wall is usually 15 feet high, and you climb straight up. The most difficulty part is to control your fear. Climbing attracts people because it’s a good exercise for almost everyone. You use your whole body, especial your arms and legs. When you climb, all your mind and body become stronger.
