Hello, my friend. It is necessary for people to exercise no matter how old they are, but everything is important. It is recommended that you keep exercising all year round, mainly taking aerobic exercise, such as swimming, Tai Ji Chuan, walking, jogging, outdoor activities, mountain climbing and traveling. The daily exercise time can be adjusted according to your body and seasonal changes, ranging from 2 hours for the elderly to 30 minutes for the elderly. Wish you good health. 0? 2
