1 . Want to add a simple movement to your daily life? Walking may be your best choice.    1    .

Walking is good for your heart

Walking is considered as cardio（有氧的）exercise, no matter the speed at which you take it. Studies show that walking can reduce the risk of heart disease and lower your resting heart rate and blood pressure.    2    . You can go for a 30-minute walk once a day or break it up into three 10-minute parts.

    3    

What benefits physical health often benefits mental health-the same is true for walking. Just five minutes of walking can lower anxiety. If you have any kind of green space nearby, try to take advantage of it. One study showed that people who went on a 90-minute nature walk reported fewer bad feelings.

Walking can improve your sleep

    4    . Getting outside in the day for a walk can also help you stay awake in the morning and get sleepier toward the night. If a nighttime walk is your preference, experts suggest you finish it three hours before bedtime.

Walking can help with fat loss

Walking is a type of cardio workout that is good for fat loss and can help you achieve or keep a healthy weight. It should be done regularly and for long periods of time.    5    . A brisk（轻快的）pace refers to a 17-to 15-minute mile, or 50%to 70%of your maximum heart rate.

2 . Although a gym membership can be nice, you don't have to have one to get into great shape! All you need is a little bit of time and space at home for yourself.     1    

Spend 5 to 10 minutes warming up before every workout.     2     Try jumping jacks, leg or arm circles, or even dancing. Just get your blood pumping. Do a progressive aerobic activity that uses the same muscles you want to work out. For instance, slowly jog if you are going for a longer run.

    3     Strength training, also called resistance training, makes you stronger and builds endurance. Try to do exercises that work a lot of muscles and add weight to increase your resistance. This helps you do a harder workout every time you exercise.

    4    You might be eager to just stop your workout when you've finished your last set of activity, but take a few minutes to do low-intensity exercises that lower your heartrate. You might drop your run into a walk or slow down your cycling, for instance.

Set achievable goals that you can break into smaller tasks. It's one thing to say you want to get fit, but that means something different for everyone.     5     It should be specific, realistic, and meaningful. Then, break down each goal into small, actionable steps so it feels like you're making progress regularly.

3 . Caribou Math Competition

Participants: 2nd graders~high school students

Cash Prizes: Yes

The Caribou Math Competition is the only worldwide math competition that is held totally online. This contest is held six times throughout the school year, and students that complete all six tests can compete for the Caribou Cup. Each contest engages students in 60 minutes of math puzzles, interactive questions, and a wide variety of problem-solving activities.

Not only is the Caribou Math Competition open to international participants, it also offers contests to elementary (小学) through high school students. The high school level Caribou Math Contests are divided into two age-based categories. Grades 9 and 10 participate in the same contests, and grades 11 and 12 participate in the same contests.

Cash prizes are given out to the top performing students and schools in the Caribou Cup after the final contest each year, which is held in May. Students are ranked based on the total of their top scores in five out of the six contests. A student's cash prize amount is determined based on their percentage score multiplied by a set dollar amount based on their ranking. Here's how that is calculated (计算):

• 1st place student: $ 100 X percentage score

• 2nd place student: $75 × percentage score

• 3rd place student: $ 50 × percentage score

• 4th and on: $ 30 X percentage score

5 . 78-year-old Nora Langdon has become an inspiration to people of all ages. She _________multiple days a week at the gym training for three hours at a time.

At 65, Langdon was determined to live a _________lifestyle. In 2007, she weighed over 210 pounds and often struggled to catch her _________while going up the stairs. She knew it was time to _________

“On the first day I started, I told myself that I’d give up because it was too _________for me.” Langdon told Good Morning America. “Then I heard my _________saying from within, ‘go back.’ So, I went back and here I am today.”

After joining the gym and watching her trainer prepare for a powerlifting meet, she _________his competition and decided to try it herself. She began with the basics — using a broom (扫帚) as a barbell before _________moving to weights. It wasn’t long before she discovered _________was her love.

Langdon has __________19 world records and quickly became one of Michigan’s best in her age range. Although Langdon has some world records under her belt, she shows no signs of __________. Her next __________? To powerlift a total of over a thousand pounds!

Langdon wants others to know that with__________and strong faith, anyone her age can get into __________. “You were __________to continue until the Lord takes you away,” she said.

6 . Water jogging is a workout method where people get into the water and copy the movement of jogging. This workout routine relies on the resistance of moving inside water to build up muscles and increase endurance (耐力).     1     This is because it is considered very effective at burning food energy.

When people attempt this workout method, it is usually important to be floating in the water at a depth that doesn’t allow the feet to touch. The tenseness of the body while doing the exercise can make it difficult to remain floating, so most people use some tools. The main devices are belts that keep people floating at an exact depth so that they are submerged (淹没) shoulder level.     2    

Water jogging can potentially be useful for almost anybody, but many of the people who try this exercise method are attempting to recover from injuries. It is considered particularly good in this situation for a lot of reasons.     3     Being removed from the effects of gravity can allow for movements that don’t put as much strain on the body, especially in the joints.

    4     For example, some movements have increased resistance underwater, including any movements of the arms. When running on the ground, there is no significant resistance against the arms, but water jogging can potentially allow a person to build up muscles in that area.

Sometimes water jogging can be very difficult for people who are just starting out.     5     To deal with the issue of boredom, some people may find ways to change the workout by mixing in different levels of intensity (强度). This can potentially decrease the sense of boredom.

9 . To keep social distancing and work at home during the pandemic (流行病) has led to less time moving around, and more time sitting and looking at screens. For many office workers, working at home means spending hours sitting at our desk.     1    . Therefore, exercise experts suggest things must be changed. Some tips here are to help you move more.

Start small

People trying to start exercising often get caught up in an “all or nothing” thinking which means either I do zero or I do two hours. And if I don’t get two hours, then it doesn’t count, or it’s not good enough.     2    . Going from no activity at all to even a little bit will indeed get some health effects.

    3    

Part of developing a good exercise habit is to know yourself well. Knowing what’s possible and what’s not realistic for you. For instance, if you’re not a morning person, don’t plan to exercise in the morning. And if you hate running, don’t run just because someone tells you it’s good for you.     4    . Arranging with a friend to work out will help you avoid struggling to get started.

Walk whenever you can

Sitting less and walking more will make a big difference. Use your stairs instead of an elevator. And if you don’t have to go out, just walk room to room back and forth to get those extra steps. If you have a meeting, use the break of that meeting to walk around.     5
