In fact, fitness is not equal to health. Fitness also depends on age and stage. You must exercise before the age of 40, and don't exercise and maintain after the age of 60. Some people don't exercise when they are young, but when they are old, they exercise hard, which violates the laws of nature and leads to physical collapse. When an old lady came to see him, she weighed only 70 or 80 Jin. She thinks that exercise can keep healthy. She insists on walking 5 kilometers after dinner every day. Even though the weather in summer is 38 degrees Celsius, her health is getting worse and worse.
We can swim and run instead of riding a bike. When people reach the age of 50, muscle and joint pain will become more and more obvious, but they can't stop exercising. At this time, you need to do some aerobic exercise to improve your heart rate, and the impact on the joints should not be too great. Therefore, experts suggest that running can be replaced by swimming and cycling.
Some old people who don't exercise much sometimes feel that they have no strength. Actually, strength is related to life span. People's muscles will shrink after the age of 40, so we must start exercising muscles in advance to delay muscle aging. But don't choose a heavy dumbbell from the beginning. You can start with a dumbbell weighing 5 kg and lift it 15~30 times each time, once a day. If you are in good health, you can appropriately increase the number and frequency of kilograms. Dumbbells can be replaced by many things, such as laundry detergent and large bottles of mineral water. , but it is best to choose professional sports equipment. )
