Enhance muscle and muscle endurance

Regular and uninterrupted jogging can enhance motivation and muscle endurance, which is our ability to maintain work and cope with emergencies. Jogging is one of the best choices.

Improve cardiopulmonary function

Persisting in jogging will increase the systolic blood volume, lower the resting heart rate, lower blood pressure, increase the content of high-density lipoprotein cholesterol in blood and improve the working ability of the body.

Metabolic detoxification

Accelerate the metabolism in the body, delay the aging of body functions, and excrete excess toxins and other substances in the body through sweat and urine.

Relieve psychological pressure

In a competitive environment, if you don't eliminate the tension, mental and psychological pressure, you will always be at a disadvantage. Moderate jogging will reduce the psychological burden and maintain a good physical and mental state.

After running, you need to do proper relaxation exercise, which helps to relieve muscle soreness.

When running, you can insert several quick walking stages to reduce the impact of running on joints.

Second: swim indoors for 20 minutes.

The benefits of swimming.

Swimming consumes a lot of energy. This is because the resistance of water when swimming is much greater than that of air when moving on land, so it is very difficult to walk in the water, and then swimming will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also beneficial to heat dissipation and consumption. So swimming consumes much more energy than running and other land projects, so the effect of losing weight is more obvious.

It can avoid sports injuries of lower limbs and waist. When carrying out weight-loss exercise on land, because obese people are heavier, their bodies (especially lower limbs and waist) have to bear great gravity load, which reduces their exercise ability, is easy to fatigue, greatly reduces their interest in weight-loss exercise, and can damage joints and bones of lower limbs. When swimming in water, a considerable part of obese people's weight is borne by the buoyancy of water, which makes their lower limbs and waist much easier and greatly reduces the risk of joint and bone injury.

2, swimming precautions

Do some warm-up activities before swimming, such as stretching limbs and moving joints. And water the head and chest to adapt the body to the water temperature and avoid cramps.

If you are tired and empty, you can't swim. Don't go into the water when you are in poor health (such as menstruation, cold or other diseases). Just after a sport, you can't swim until the sweat disappears. If you don't pay attention to these problems, it's easy to get dizzy or cramp.

Before practicing diving, be sure to find out the water depth in the jumping area to avoid hitting your head.
