1 . In 1665, Johannes Vermeer, one of the greatest painters in Netherlands, completed his masterpiece “Girl With a Pearl Earring.” On an April day 357 years later, Janine Strong slowed her bike to stop, paused her fitness app, and watched as the snaking line of her cycling route drew the shape of Vermeer’s masterpiece over the streets of Brooklyn.

Ms. Strong creates what has come to be known as “GPS art” — a practice that uses the Global Positioning System mapping capabilities of modern phone apps to create digital drawings with an athlete’s route. It has grown with the widespread availability of satellite tracking for use by ordinary people. In fact, the idea has been around since before the popularity of smartphones for fitness like Strava released in 2009.

In 2003, The New York Times Magazine told of how Jeremy Wood got the idea for GPS art. Mr. Wood said while he was using a GPS tracker on a flight and the plane flew in a holding pattern above Heath-row Airport, he was attracted by the pattern appearing on his Garmin GPS device. In recent years, technology has advanced enough to create visual maps in real time using a phone or smart watch.

“I get bored cycling on the same path in the same streets,” Ms. Strong said. “Creating GPS art gives me more reasons to hit the pavement, which makes cycling a lot easier. I always have a big smile on my face when it works out and I upload it and it’s done,” she added. “It’s a very satisfying feeling.”

To complete her digital vision of “Girl With a Pearl Earring,” she biked almost 50 miles around southern Brooklyn, carefully checking Strava to make sure each turn, circle, and straight line was achieving the shape of earring and head covering of Vermeer’s original.

2 . If you always sit indoors for too long, putting on weight may become a trouble. Tired of all that fat? If so, these sports can help you burn the most calories.

Running

“Running is one of the best calorie burners out there,” qualified personal trainer Daniel Saltos says. An average person can burn anywhere from 500 to 1000 calories in one hour of running. “Speed, pace, and tolerance are all factors that can impact this range. But running uses every muscle group in the body, allowing you to burn more calories.”

Swimming

“Swimming is a workout that produces the lowest impact on body while it still can burn 500 to 600 calories in just 30 minutes,” Saltos says. Swimming also improves heart health and increases strength—all great reasons for playing in the water.

Boxing

Not only is boxing a great way to release energy, but it also helps improve balance, builds up tolerance and strengthens the upper body and core. “Boxing helps you get a good calorie burn, too, with the average person burning up 400 to 800 calories in an hour session,” Saltos says.

Rowing

The pushing and pulling motion of rowing machines targets multiple muscle groups including the arms, core, and back, helping you to burn more calories. “An hour of rowing will burn 400 to 600 calories on average,” Saltos says.

3 . Many people lead busy lives and think they barely have time to work out every day.     1     They are short workouts that often involve high-intensity(高强度的)exercises. Here we explore some reasons to do micro workouts.

Require Less of a Time Commitment

Committing to exercising for a certain amount of time per week can be difficult, especially when you do not have the time or motivation to work out for an extended period. Microworkouts are good alternatives. They take up only 10 to 30 minutes of your day. Many people spend much longer scrolling through social media each day.     2    

Make Scheduling Workouts Easier

It can be challenging to commit the time needed to exercise every day,but it can also be hard to fit a workout into a tight schedule. However, a study suggests that it may be possible.     3     For example, walking your dog, using the stairs, parking farther away from adestination, or walking during your lunch break are all ways you can try.

Need No Equipment

Investing in expensive home gym equipment can be a real burden. When you decide to domicro workouts, though, you don’t need a bunch of equipment.     4     For example, you may choose to do steps on your stairs, run on the spot, or even do some star jumps. Since youcan choose what type of workout you’d prefer to do, it means that you can exercise wheneveryou please.

    5     Now that you know all about micro workouts, you can add them to your day.Get as creative as you please and think about the types of movements that suit you. You neverknow-it might just boost your health and wellness.

A．Ready to get moving?

B．You just fit it into your routine.

C．Fitness should be simple and convenient.

D．So it should be a relatively easy time commitment.

E．If you feel this way, you may be interested in micro workouts.

F．Can micro workouts give the same benefits as longer workout sessions?

G．Instead,you can use things around your home to empower your workout.

6 . Online training is one of the fastest growing parts of the fitness industry. If you’re considering joining the online fitness community, consider these benefits and drawbacks.

One of the most popular reasons for working out following an online video is that it offers ultimate convenience. No need to roll out of bed at 5 a. m. to attend that 6 a. m. boot camp class, which may end up being full when you arrive.    1    And what if you’re on the road? No problem. You can access your workout video through your phone.

    2    Most online fitness programs are much less expensive than similar offline programs—most range in cost from $ 10 to $ 20 per month. Some are even free. For example, the online Les Mills+program offers a free 30-day trial of its 1,500-plus workouts.

Online training also has broad offerings. When you head online, you have instructors from around the globe, all ready and willing to help you master your favorite moves.    3    Just because there isn’t a Krav Maga class in your area doesn’t mean you can’t go online to find one led by qualified instructors.

All these are undoubtedly positive-online training provides fitness resources to general consumers wherever they are, without requiring access to a gym or fitness studio.    4    

Very few online fitness programs enable the instructor to see you, check your form, and offer corrections based on your performance.    5    This is particularly concerning for beginners, as they’re more likely to do incorrectly. Besides, if you struggle with self-motivation and prefer a social workout environment, online fitness may not be for you.

A．Another is the price.

B．But it’s not without problems.

C．The same goes for different types of exercise.

D．However, online personal training isn’t for everyone.

E．Instead, you can turn it on at home at your convenience.

F．That being said, online workouts aren’t perfect when it comes to safety.

G．This means you could perform exercises wrongly, or even unsafely, without knowing it.

7 . If you’ve fallen off the exercise wagon (健身车), it can be hard to get back into it even if you know about its advantages.     1    

Step 1: Be gentle with yourself.

You are probably worried that you’re not as fast as you used to be.     2     If you’re busy judging your performance and what’s not happening, you can’t focus on what it is. Just be brave to start over from where you are now.

Step 2:     3    

Be smart about the frequency and duration (持续时间) of your exercise, especially during your first few weeks back to exercise. Spreading them throughout the week rather than being a weekend warrior (勇士) and gradually increasing your activity levels will help you avoid injury.

Step 3: Make things convenient.

    4     When it comes to finding the time, keep your training short and effective. In this way, you don’t need to think of it as a time-consuming activity. All you need is 15 to 30 minutes of running to keep up your workout.

Step 4: Try getting it done first.

Everyone has a different sweat style, whether you prefer dawn exercise or are more of a night owl. By getting the exercise done first, you have less chance to make excuses to leave out the workout later in the day.     5     That feels good.

A．Set a realistic plan.

B．Don’t worry about that.

C．Exercise anytime, anywhere.

D．Try your best to reach your previous level.

E．There are more people trying to keep healthy.

F．Once the exercise is over, you’ll think you’ve already achieved something.

G．Here, some experts offer four simple steps you can use to get back into it.

8 . As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.

“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.

Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic (无氧) exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.

“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didn’t change, he says.

“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all.”

Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.

1. What does Levine want to explain by mentioning the rubber band?

A．The right way of exercising.	B．The causes of a heart attack.
C．The difficulty of keeping fit.	D．The aging process of the heart.

2. In which aspect were the two groups different in terms of research design?

A．Diet plan.	B．Professional background.
C．Exercise type.	D．Previous physical condition.

3. What does Levine’s research find?

A．Middle-aged hearts get younger with aerobic exercise.

B．High-intensity exercise is more suitable for the young.

C．It is never too late for people to start taking exercise.

D．The more exercise we do, the stronger our hearts get.

4. What does Dr. Nieca Goldberg suggest?

A．Making use of the findings.	B．Interviewing the study participants.
C．Conducting further research.	D．Clarifying the purpose of the study.
