Everyone knows exercise is good for you.   1   When you see the health benefits of physical activity, they can seem almost too good to be true.
Exercising consistently can help prevent heart disease and muscle weakness.   2   Besides, it can control and treat chronic conditions, improve brain function and sleep as well as improve your mood (心情) and general quality of life. And it does all that without causing the side effects of some of the prescription drugs used to treat those conditions.
 Becoming and remaining consistently active can be a challenge, even when you understand all the benefits.   3   You can take walks around the neighborhood, hit the gym or spend money on home fitness equipment.
Make personal routine to lifestyle
Some people prefer exercising by themselves at home; others prefer a social environment.   4   Strength training (such as weightlifting) can benefit your bones and your muscles, but aerobic (有氧的) exercise in particular strengthens the heart. Running or jogging can burn calories more quickly than walking and can potentially offer more bone­strengthening benefits. For variety, try swimming, biking, group exercise classes, dancing, hiking or sports such as tennis.
Make every minute count
