2 . Exercising regularly not only helps you keep slim, but also improves your overall health and well-being. Different exercises produce different results, as they focus on alternate parts of the body. There are four broad exercise categories: endurance, strength, flexibility, and balance. Many people often only focus on one exercise type, but including all four in your workout will produce better results and reduce your risk of injury.

Endurance

Endurance exercises increase your breathing and heart rate. By doing endurance exercises, you are working to keep your heart, lungs, and blood-flow system healthy while improving your total fitness. Over time these activities will make everyday activities seem easier.

Strength

If you want to build up your muscles, then strength exercises, which are also known as “resistance training”, are right for you. Even the slightest increase in strength can make a huge difference in your ability to carry out daily tasks. Developing strong muscles also reduce your risk of weak bones.

Flexibility

Flexibility exercises help stretch your body’s muscles. This allows for more freedom of movement for other exercises and can also improve your range of motion, posture, ability to breathe deeply, and blood flow. Also, it reduces the muscle tension caused by stress.

Balance

Balance exercises help prevent falls and are especially important to older adults, helping them stay independent. Most good balance exercises are ones that keep you constantly moving with your feet on the ground. Heel-to-toe walking and standing on one foot are simple ways to improve balance.

3 . Depression（抑郁症）in young adult males, ages 18 or 19, is linked to a 20% greater risk of having a heart attack in middle age, according to a new Swedish study.

The link can be partly explained by poorer stress resilience（抗压能力）and lower physical fitness among teens with mental disorders.

The research included 238,013 men born between 1958 and 1962 who were given examinations in adolescence（青春期）and were then followed into middle age（up to the age of 58 years）. A total of 34,503 men were diagnosed（诊断）with a mental disorder.

The study found that a mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood，the risk of heart attack was 20%higher among men with a diagnosis.

“We already knew that men who were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience,” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”

“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fit as they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.
