2 . There are many ways to travel within a city. We can walk, cycle, or take a bus. But no matter which way we travel, we have to follow the route (线路) the city planners laid down for us.

Parkour practitioners (跑酷爱好者), however, see the city in a completely different way. To them, there are no designed routes. There are no walls and no stairs — they jump, climb, roll and crawl to move across, through, over and under anything that they find in their path. The city is their playground.

The International Gymnastics Federation (FIG) has noticed that this activity is drawing more and more people to it — there are 100, 000 people taking part in parkour today in the UK alone, according to The Guardian — and how it is helpful for people to be much stronger: It trains coordination and balance. So the FIG is thinking about recognizing parkour as a new sport and adding it to the Olympics by 2024.

But parkour practitioners themselves don’t seem to be happy with the idea. They see parkour as “a lifestyle”, wrote the website NextSportStar. “It’s a competition against the conditions rather than just a sport.”

Indeed, many do parkour just to “escape the daily routine and experience the city in different ways”, wrote reporter Oli Mould on The Conversation. They see parkour as a way to express themselves through relaxing moves and creative routes while freeing themselves from the pressure.

It’s great that the FIG wants to develop a new sport and stay close to a new cultural form. But it would be greater if they knew that not everything in life is a competition.

3 . Fitness Magazine recently ran an article titled “Five Reasons to Thank Your Workout Partner.” One reason was: “You’ll actually show up if you know someone is waiting for you at the gym, ” while another read: “    1    ”   With a workout partner, you will increase your training effort as there is a subtle (微妙) competition.

So, how do you find a workout partner?

First of all, decide what you want from that person.     2     Or do you just want to be physically fit, able to move with strength and flexibility? Think about the exercises you would like to do with your workout partner.

You might think about posting what you are looking for on social media, but it probably won’t result in a useful response.     3     If you plan on working out in a gym, that person must belong to the same gym.

My partner posted her request on the notice board of a local park. Her notice included what kind of training she wanted to do, how many days a week and how many hours she wanted to spend on each session, and her age. It also listed her favorite sports and activities, and provided her phone number.     4    

You and your partner will probably have different skills.     5     Over time, both of you will benefit—your partner will be able to lift more weights and you will become more physically fit. The core (核心) of your relationship is that you will always be there to help each other.

4 . Playing sports offers you more than just physical benefits (好处).     1     The benefits are the same whether or not you’re good at sports. If you are not good enough to play competitively on a school team, you can play sports with your friends.

Making new friends.

Playing sports enables you to create friendships you otherwise might not have formed.     2     You play together happily and gradually know each other. Many times, the friendships you create on the field remain strong when you are not playing sports.

Understanding the value of health.

Taking part in sports improves your health in many ways.     3     This gets you thinking about what to eat and how to treat your body so as to achieve the highest performance levels. Thus, playing sports can lead to better eating habits and prevent you from becoming too fat.

Building team spirit.

Sports provide children with the important lesson of learning how to work in a team.     4     By working together they will learn each other’s strengths and weaknesses and will be better able to decide and work out the best plan for the team. This will without doubt help them in their future lives and jobs as well.

Playing sports requires a lot of time and energy. Some may think this would take students’ attention away from schoolwork. However, the opposite is true. Sports require memorization, repetition and learning — skills that are directly relevant (有关的) to schoolwork.

5 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

8 . Why play sports? You might say “to get exercise” and you would be right. To have fun? That's true, too. But there's more.     1     According to the Women's Sports Foundation, girls who play sports get a lot more than just fit.

Girls who play sports do better in school. You might think that athletics will take up all your study time.     2     Exercise improves learning, memory, and concentration, which can give active girls an advantage in the classroom.

Girls who play sports learn teamwork and goal-setting skills.     3     When working with coaches, trainers , and teammates to win games and achieve goals, you're learning how to be successful. Those skills will serve you well at work and in family life.

Sports are good for a girl's health. In addition to being fit and keeping a healthy weight, girls who play sports are also less likely to smoke. And later in life, girls who exercise are less likely to get breast cancer or osteoporosis(骨质疏松症).

Playing sports improves self-confidence.     4     Why? It builds confidence when you know you can practice, improve, and achieve your goals. Sports are also a feel-good activity because they help girls get in shape, keep a healthy weight, and make new friends.

    5     Playing sports can reduce stress and help you feel a little happier. How? The brain chemicals leased during exercise improve a person's mood. Friends are another mood-lifter. And being in a team creates tight bonds between friends. It's good to know your teammates will support you-both on and off the field!

10 . For many Americans, regular exercise is a complicated commitment—one made at the beginning of January that fades out within weeks or months. Busy work schedules, a lack of motivation and unease towards exercising in public all contribute to the discouraging statistics that only around a quarter of adults exercise enough per week.

This month, enterptiser Trent Ward and designer Yves Behar are uncovering their design for a mirror fitness system, Forme. Forme is reflective like a mirror, uses machine learning to heighten workouts, and offers attachments including ankle belts, rope handles and a heart rate monitor. When not in use, the two arms that form the resistance pulley (滑轮) system fold behind it and the display screen disappears, turning Forme into a simple full—length mirror.

Interest in home exercise has particularly increased recently around the world. Home workout apps have seen a significant uptick in downloads, and trendy brands like Peloton have rolled out free virtual workouts for everyone stuck indoors. One French athlete who was kept away from others chose to run an entire marathon on his 23-foot balcony.

But beyond the new restrictions affecting daily workout routines, Ward and Behar are tapping into the same concerns that have made every home workout appealing：the ability to save time and sweat in the privacy of one’s home. In an age of personal metrics (衡量标准)--where one can measure their heart rate and sleep cycles with smart watches and train for marathons with AI smart sneakers----Ward and Behar want to improve exercise through machine learning. Forme evaluates performance and adjusts weights accordingly. Easy access to one’s own performance data also makes it easier to track that progress and stay motivated.

Though it’s too soon to tell if mirror gyms will be the trend of the late 2010s to 2020s, Behar explained that having a screen in the home can become the basis for more than just fitness, such as shopping or telemedicine.
