Attention 1: Don't exercise too much. People who used to take part in physical exercise often can increase the amount of exercise appropriately. Generally, the pulse does not exceed 1 10 times/min, and the maximum pulse does not exceed 120 times/min. Old comrades who didn't often take part in physical exercise or didn't take part in physical exercise at all in the past should first choose sports that suit them.

Note 2: Warm-up activities must be done before exercise, and the warm-up time is about 10 ~ 15 minutes. Doing so can prevent ankle sprain, waist sprain and nerve damage.

Note 3: Do some tidying activities after exercise. Because people's capillaries dilate after exercise, if they sit still on the ground and their blood can't return to the heart at the far end of the body, they will feel depressed. Old comrades with hypertension and heart disease should take a walk after exercise, buffering 10 minutes or so.

Note 4: master the exercise time. The best exercise time for elderly friends is about 40 minutes, not less than 30 minutes on the left and not more than 1 hour on the right.

Equipment should also be paid attention to at ordinary times: the fitness equipment of community "fitness path" can generally be divided into three types: body structure exercise (also called anaerobic exercise), aerobic exercise and body flexibility training.

Using these instruments can help people to treat biomechanical diseases, excess energy diseases and neurological and mental diseases. According to the functions of all kinds of equipment, we divide the sports equipment in the community "fitness path" into four types.
