1 . When Muhammad Ali was 12 years old, someone stole his bicycle. It was a shiny new bike. Ali was very __________ and told a policeman he wanted to use his __________ to kill the thief. The officer __________ him to back up those “fighting words” by learning how to box.

During the next 25 years, Ali had a burning __________ to become one of the best boxers of the 20th century. He won a gold __________ at the Olympic Games. He went on to earn the title of world heavyweight boxing champion three __________ times. __________ his fights became major events watched by millions of people around the world.

Young Ali quickly made his mark in the __________ ring (拳击场). Instead of being a(n) __________, he turned professional after winning a gold medal in the Olympic Games in 1960. Four years later, he __________ Sonny Liston to __________ his first world heavyweight champion title.

In 1974, Ali __________ the world heavyweight title again by __________ George Foreman. Then he met Joe Frazier in the Philippines, to do __________ for the third time. It was __________, but Ali won that fight. Ali __________ his heavyweight title six more times before he __________ to Leon Spinks in February 1978. But Ali beat his __________ and got back the title seven months later.

Ali __________ in 1981 with a record of fifty-six wins and five losses. In 2005 he was __________ the Presidential Medal of Freedom.

2 . The U.S. Department of Health and Human Services recommends that adults do at least 150 minutes of moderate to higher-intensity physical activity each week, and it should be in ________ of at least 10 minutes each for substantial health benefits, which has led many to ________ about the inefficacy of brief activities. Why people take two minutes going up the stairs if more than 10 minutes is ________ to make it worthwhile for health?

But now a study suggests something else: go ahead, take the stairs! Every minute ________ toward reaching the 150-minute goal, whether it’s part of a 10-minute period of activity or not. The purpose of the study conducted at the University of Utah was to see if moderate to vigorous physical activity in less than 10-minute episodes was ________ to weight outcomes. The study, published in the American Journal of Health Promotion, found that each minute spent ________ in some kind of moderate to vigorous physical activity — be it walking the dog, vacuuming, or taking the stairs — was associated with lower BMI and lower weight.

“The idea here is, you can do a minute at a time and that’s not a problem,” Jessie Fan, lead author of the new paper and a family and consumer studies professor at the University of Utah, told Today.

For the women who participated in the study, each minute spent in higher-intensity activity was associated with a 0.7 drop in body mass index (BMI). For a 5'4" woman, that means a ________ of nearly half a pound, which may not sound like much, but that’s just for one minute. Little by little, they add up.

The authors concluded that the current 10-minute ________ guideline was based on health benefits other than weight outcomes and that their findings showed that for weight gain ________, accumulated higher-intensity physical activity bouts of less than 10 minutes are quite ________, supporting the message that “every minute counts.”

When it comes to your brain, it also rings true. An April 2019 study in Jama Network Open looked at how exercise affected the brain, and even short bursts ________ 22% greater brain volume.

“Our study results don’t ________ moderate or vigorous physical activity as being important for healthy ageing. We are just adding to the science, ________ that light-intensity physical activity might be important too, especially for the brain,” Dr. Nicole Spartarno, first author of the study from Boston University said.

“I think it’s easier for people to ________ that message,” Fan says. “Otherwise, if they don’t have a block of time they might be ________, and they don’t do anything.”

Over the years, everyone in the Fit Nation family has achieved great success, but in many cases, the pounds don't always dramatically _______ .
