Good for your brain.

Work your muscles.

Every time you swim, it is like doing a mini-resistance workout. Each kicks and pull works your muscles more than you could imagine, especially your arms, shoulders and gluteus — the muscles that are inactive all day when you’re sitting at your desk.     3     So along with building fitness, it is a wonderful full body exercise.

Lift your spirits.

    4     They can cause a positive feeling into your body which makes you happy. Swimming has been shown to reduce stress and tension. The repetition, movement and the breathing can help you to relax , and that’s why swimming is also regarded as a relaxing exercise.

Have a chat in the lap pool, join a swimming club or get involved in social water sports to get to know people in your community. Besides, the great thing about swimming is that you can do it — rain or shine. Although your backyard pool, the river or beach cools down over winter, most inside swimming pools run heated pools year round, so you’ve got no excuse to stop swimming.

4 . Five tips for safe running

We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.

Running is good exercise, but it can be hard on the body.     1    

Take it easy. Do not run too much, too soon or too fast. Most people get running injuries (受伤) when they push themselves too bad. The body needs time to get used to increase in distance or speed.     2    

Listen to your body. Most running injuries do not come unexpectedly (意外地).     3    

They may include body aches, sore muscles (肌肉) and pain that does not go away.

    4     There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.

Take good notes. Take time after each run to write down what you did and how you felt. Look for patterns, things that happen over again. These notes will help you find the best exercise for you.

Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some form of cross training to improve muscle balance and to help you stay injury free. They say, besides running, swimming, yoga, and riding a bicycle are good exercises.     5    

5 . 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.

9 . Do we have a movement signature?

As humans, we have several qualities that separate us from one another, such as our fingerprints.     1    

According to a recent study, each person has a unique movement signature (鲜明特征). Depending on the person, these differences can be subtle or pronounced.

    2     For the study, scientists attached electrodes (电极) to muscles in the legs of volunteers. The volunteer were then asked to perform activities such as walking on walking machines and riding stationary bikes (健身车), which were adjusted according to each person’s physical appearance in order to make sure everyone was judged using the same standards.

Scientists fed the information to a computer along with the volunteer’s name.     3     Next, the computer was fed information without the user’s name and it could identity the person correctly 99% of the time. The outcomes of the study showed that each of us does have something unique about our general movements.

    4     Since this is just a pilot study, scientists will do more tests to see if the signature changes with age and weight changes. But with a deeper understanding of the science of movement, doctors could possibly develop more intricate prosthetics (复杂精细的假肢).     5     Whether that’s cool or frightening is up to you to decide.

10 . Reasons Why Running Is the Easiest Exercise

Some people think that running is hard. I once thought that too.     1     Here's why it is such an easy activity to start and stick to.

☆It can be as easy or hard as you want.

Many people start running by going out and running as fast as they can for as long as they can. That is not so fun.     2    But easing into it is a different story. Start slowly and cover a short distance. Then gradually work your way up. In this way, running can be pain-free and actually wonderful.

☆    3    

Classes at the gym are great but they always end up never working for me. With a busy life, I find it hard to attend a class. On the other hand, with running, you just need to find the time whenever you can, here and there, and change it around.

☆The gear (装备) is simple.

    4     However, that's really just about all you need. There is no gear. Expensive sport-specific clothes are available (可用的) but not required. If you fall in love with running, you may think you need some seasonal running clothes. Even so, that will be cheaper than bike gear.

☆You can do it anywhere.

You can run in the city. You can run in the county. You can run on a track, in a park, on the steer even on the beach. You can run at home. You can run when you travel. And in fact, running around new cites when traveling is great fun.     5
