Jogging is the most popular aerobic exercise in the world today, which has a good effect on maintaining good heart function, preventing heart function decline, preventing muscle atrophy, preventing coronary heart disease, hypertension, arteriosclerosis and obesity. You should not jog too fast, but keep a constant speed. Subjectively, it is not uncomfortable. Objectively, it is appropriate to control the heart rate per minute at 180 minus the age. For example, a 60-year-old person's heart rate during jogging should be 180-60= 120 times per minute, and the exercise time should be no less than 20 minutes and no less than 4 times per week.

2. Run away alternately.

There are two ways to run and walk alternately: one is to walk first and then run, that is, walk first 1 minute and then run 1 minute alternately. You can adjust and increase the amount of exercise every two weeks, shorten the walking time and increase the running time. The other is to exercise from walking and gradually transition to jogging instead of walking. Exercise can last for 20 to 30 minutes, not less than 4 times a week.

Step 3 swim.

Swimming fitness exercise is a kind of whole-body exercise that uses the buoyancy, resistance, friction and weightlessness of human body in water, and is suitable for all kinds of people. The intensity of swimming is similar to running. The heart rate per minute can be controlled at 180 minus age and minus 10. For example, a 60-year-old person's heart rate during swimming can be controlled at180-60-10 =110 times per minute.
