2. Keep your knees straight and spread out, not stiff and inflexible, but let yourself walk without pressure. Knee straight, stride longer. You must straighten your knees when striding. As for how big the stride is, just make you feel comfortable. There is a trick to straighten your knees: when you straighten your knees, your upper body leans forward slightly, as if it were going to fall down. Push the hind legs to the ground, so that the front legs and knees are naturally straight and the steps are big. In addition, when the front foot moves forward, the waist on the same side seems to move forward, and the waist and legs should be effectively coordinated. When walking, the thighs should drive the calves, the knees should be straight, and the stride should be large. When the knees are straight, the upper body naturally stays straight, and the speed can come out. That's why you straighten your knees. If you walk with your knees bent and only part of your leg muscles work, you will feel tired easily and your legs will soon lose strength. When the heel touches the ground first, then the body center of gravity moves to the toes and the forefoot touches the ground, the heel touches the ground first and the body center of gravity falls on the heel. Then, the center of gravity of the body "rolls" from the heel to the toe through the sole of the foot, and finally reaches the toe. In fact, when someone walks, the center of gravity of the body immediately shifts from the heel to the toe, and some people land on their toes, which is a special case such as ballet. Regarding the rolling of the body's center of gravity from the heel to the toe, there are several points worthy of attention: First, the heel does not bear all the weight, nor does it mean that the heel will hit the head when it steps on the ground.
3. Step forward with your feet, stretch your upper body, straighten your knees, and naturally step forward when walking. In this process, the key is to straighten the hind legs. Keep your legs straight, your knees straight, and your front feet naturally move forward. The front foot steps forward straight, and the inner footprint of the foot forms a straight line. Most people always feel that their toes are a little outward, and sometimes they have to be outward in pursuit of speed. Some people walk with their toes facing outwards, commonly known as splayed feet, which are relatively stable. There is a certain relationship between the movement of the front foot stepping forward and the shift of the center of gravity of the back foot. When the foot touches the ground, the center of gravity of the body rolls on the whole sole, moving from the heel to the toes, and the hind foot kicks outward around the first, second and third toes, forming the action of the front foot stepping forward. The rest of the sole plays an elastic role, making walking smooth and smooth. By striding, you can master the essentials and rhythm of walking with your head up. By the way, the way of "crab step": this is the toe throwing outward, the heel landing on the outside and the big toe kicking on the inside. In addition, it also shows bending, bending and hunchback, and the feet should not move forward.
4, swing arm, swing arm is also very important for walking, often see some people, when walking with their hands in their pockets, this is not the correct way to walk. Walking with your shoulders folded like this, you will feel very loose when you walk. Whether the arm is placed well depends on whether the movements of the hands and feet are synchronized. Because in this movement, hands and feet, or arms and legs are closely related. The movements of arms and legs are also interrelated. The right foot is forward and the left hand swings forward, especially when the knee is straight and the foot is forward, corresponding to the movement of the foot, the arm naturally swings outward. If you swing wider than your shoulders, your knees will bend easily. When swinging, it is better for your thumb and fingers to touch clothes than clothes. In the state of no force, when the arm swings, the elbow naturally stretches and folds. Recently, a training method is popular in the United States, which is called "sports walking". This wind also spread to Japan. Its characteristics are that the arms should be set at 90 degrees, the hips should also swing from side to side, and the spirit should be full. American "walking" may be suitable for training, but there are many human factors. Regardless of its advantages and disadvantages on the flat ground, at least this method is not feasible everywhere. So, let's naturally raise our arms.
