Control diet and exercise, fat people should have self-control. My best friend has lost weight after drinking three cans for more than a month 13 kg. The effect is good. Exercise can be divided into aerobic exercise and anaerobic exercise. Running fast belongs to the latter, which can enhance explosive power and reaction speed, maintain endocrine balance and reduce the risk of falling. Now it is generally believed in academic circles that the elderly also need some anaerobic exercise. Old people run fast, so they should take protective measures to avoid wrestling and fatigue. You can also practice supine push-ups, pull-ups, push-ups and so on. Strengthen the strength of limbs and waist and back. This will have a better effect.
