2 . Risks of Overtraining
Getting in shape and training for an event such as a marathon requires long-lasting and intense physical commitment.
Specifically, overtraining is a set of signs that occur when your body is not able to recover sufficiently before going into your next workout.
The structures and systems of your body adapt to the demands you have placed on them before the rest time. If your workout slightly goes beyond your current ability, it will adapt toward what you did in a positive way.
Two main factors are necessary in recovery: nutrition. and rest. Good nutrition, including water and protein intake, is extremely important, especially within 40 minutes of your workout.
One of the best ways to prevent overtraining is to focus on your morning resting heart rate.
A.It's easy to measure and track. |
B.Allowing time for recovery is also essential. |
C.The problem is that they show up very gradually. |
D.Below are the signs and symptoms of overtraining. |
E.Listening to your body will assure you of your fitness goals. |
F.If far beyond, it'll take longer to adapt and may cause injury. |
G.We generally assume regular intense exercise good for our health. |
3 . Spending time outdoors has long been linked (联系) to better health. Gardening goes beyond just beautifying outdoor spaces—it can have a deep effect on our physical and mental (身心上的) health.
Gardening involves physical activity that works all the main muscle (肌肉) groups, which is helpful for overall health. “Activities such as digging, planting, weeding and harvesting require movement and can help to improve strength,” said Clayton, CEO of an online lawn care company. “Performing these activities regularly can help burn calories, and keep a healthy weight.”
Beyond burning calories and building muscle, lots of studies have shown that gardening can improve the immune system (免疫系统). The Centers for Disease Control and Prevention (CDC) recommends that people get at least 150 minutes of exercise each week, and gardening is listed as a suitable activity. Doing garden work for that time each week can reduce the risk of obesity, high blood pressure and heart disease. Additionally, spending time outdoors makes us get close to natural sunlight, which is important for vitamin D synth.
Gardening provides a chance for social connection, too. It can be a shared activity among family members, friends or neighbors, building relationships and a sense of belonging.
Gardening also offers cognitive (认知的) benefits. It excites the senses, improves focus and encourages problem-solving and creativity. It provides a chance to learn about plants, ecosystems and the environment, developing a deeper understanding and appreciation for nature.

5 . Jumping rope is popular but we tend to ignore (忽视) its benefits.
Since most of your major muscles are working when you jump rope, the exercise creates a lot of heat in the body. Your body needs to burn more fuel to produce this energy, so it burns lots of calories. It burns more calories than any other exercises, such as jogging, cycling and swimming.
Improves coordination (协调)
Jumping rope requires good coordination, especially as you advance to more skilled moves.
Reduces injury risk
With your improved coordination from jumping rope, you’ll be less likely to get hurt either during exercise or in daily activities.
Improves heart health
Since jumping rope gets your heart pumping, it’s great for your cardiovascular system and heart health. Jumping rope can increase your VO2 Max (最大摄氧量), the measure of the maximum amount of oxygen a person can breathe during exercise. The higher someone’s VO2 max, the more cardiovascular endurance (耐受力) they have.
Jumping rope gives us a full-body workout with just one piece of equipment and one move.
A.Burns calories |
B.Improves muscles |
C.It benefits us not only physically but also mentally. |
D.You can quickly swing the rope twice within each jump. |
E.It may even be more effective than other forms of exercise. |
F.Jumping rope forces you to move your upper and lower body together. |
G.So jumping rope helps you stay calm, clear and focused in everything you do. |
6 . Green exercise is a term used to describe any type of physical exercise that takes place in a natural environment rather than in a health club or gym.
A slightly different approach to green exercise puts more stress on the fresh air, sunshine and involvement with the natural world, rather than the equipment or clothing used during the exercise.
Many consider green exercise helps to reconnect human beings with the natural world. The interaction with nature helps to lower people's blood pressure, refresh their mind, and actually improve their self-esteem.
Not everyone believes that the green exercise is more beneficial than working out in a health club or gym.
A.A green gym uses as little equipment as possible |
B.Spirits are also believed to be positively affected |
C.Opinions on what truly green exercise means differ |
D.Green exercise includes a range of activities exposed to nature |
E.So riding a bicycle in the forest can be called a type of green exercise |
F.It usually doesn't use fitness equipment that is normally found in a gym |
G.Some point out that many health clubs are built to make full use of natural light |

9 . A new study involving nearly 50,000 people from four continents offers new insights into identifying the quantity of daily walking steps that will best improve adults’ health and longevity(长寿), and whether the ideal number of steps differs across people of different ages. The study represents an effort to develop an evidence-based public health message about the benefits of physical activity. The often-repeated 10,000-step-a-day saying grew out of a decades-old marketing activity for a Japanese pedometer(计步器), with no science to back it up.
Led by physical activity professor Amanda Paluch, an international group of scientists conducted an experiment among adults aged 18 and older. They grouped the nearly 50,000 participants into four comparative groups according to average steps per day. The lowest step group averaged 3,500 steps; the second, 5,800; the third, 7,800; and the fourth, 10,900 steps per day. Among the three higher active groups, there was a 40—53% lower risk of death, compared to the lowest step group.
More specifically, for adults 60 and older, the risk of early death leveled off at about 6,000—8,000 steps per day, meaning that more steps than that provided no additional benefit for longevity, while for adults younger than 60, about 8, 000—10,000 steps per day.
“So, what we saw was this continuing reduction in risk as the number of steps increases, until it levels off. Interestingly, the study found no definitive association with walking speed.” Paluch says.
The new study supports and expands findings from another study led by Paluch before, which found that walking at least 7,000 steps a day reduced middle-aged people’s risk of early death. “There’s a lot of evidence suggesting that moving even a little more is beneficial, particularly for those who are doing very little activity.” Paluch says. “More steps per day are better for your health.”
