For the elderly, exercising the lower limbs is essential

　　The decline in the lower limbs indeed occurs earlier than that in the upper limbs. The legs are the primary weight-bearing limbs of the human body, possessing the strongest joints and bones. As one ages, there is a degree of physiological loss of muscle mass and bone calcium, and the elasticity of blood vessels also decreases gradually. As a result, the accuracy and speed of movements in the lower limbs become reduced.

　　Regularly swinging your legs and twisting your knees can help to improve blood circulation and enhance the flexibility and resilience of the tissues surrounding the knee joints. During exercise, the duration and intensity should be adjusted according to one's own conditions, with the goal of avoiding significant fatigue or discomfort both during and after the exercise. For elderly people who often experience fatigue in their legs and feet, it is recommended to elevate their feet daily to a level at or slightly above that of the heart, and then use both hands to gently rotate and massage the calves for 3 to 5 minutes in order to improve blood circulation.

　　When swinging your legs, use one hand to support a tree or wall while keeping your upper body straight. First, swing your lower legs forward, causing your toes to point upward and forward, then swing them backward, with your toes pointing backward and the tops of your feet straightened, as well as your legs. Swing each leg 20 to 30 times in turn, for a total of 2 to 3 cycles. When twisting your knees, keep your feet parallel and close together. Bend your knees slightly and squat down, placing your hands on your knees. Twist your knees in a clockwise direction 10 times, then in a counterclockwise direction. Repeat this 3 times. After twisting your knees, gently move your limbs around in a casual way—such as shaking your arms and legs, squatting and standing up, or marching in place.

　　footed Exercise There are many methods, and here are two simple and easy-to-follow approaches: one is active practice, and the other is passive practice. These two methods can be used in combination as well.

　　Dynamic Training Method

　　Walk more. Sitting for long periods not only hinders the circulation of qi and blood in the body, causing the feet to cool down, but also increases the risk of obesity. Generally speaking, after walking continuously for 30 minutes, your feet will start to feel warm. Therefore, for those who spend a lot of time sitting and feel their feet getting cold, it is advisable to try to walk for 30 minutes every day.

　　Quiet Practice Method

　　Move your feet around while you are sitting. There are two areas involved in this activity: the toes and the ankles. The way to move the toes is by scratching downward and stretching upward, while the way to move the ankles is by rotating them slowly in circles. These exercises don’t require much space; you can do them while sitting in your office or quietly on the bus.

　　99 enthusiastic doctors offer some warm reminders: the elderly Maintaining appropriate exercise, especially targeted workouts for the lower limbs, can help slow down the loss of muscle tissue and bone calcium, thereby delaying the aging process of the legs. The elderly can choose activities such as walking, brisk walking, or jogging to stimulate the muscles and acupoints in their legs and feet, promote blood circulation in these areas, and regulate overall bodily functions.
