"As the name implies, the crab line is to walk sideways like a crab. It originated in Europe and is particularly popular in Japan now. According to a friend who came back from Japan, many people practice this step in parks or exercise places in Japan every morning or evening. Some places and even the streets are' crabs'! "

"

Crab line looks really ugly, but it's good for your health. There is a muscle group on the inner thigh of human body. Because many people walk incorrectly, their knees are outward and their legs are very apart. Over time, it will cause uneven stress on the joints of the legs and produce various pains. But normal walking posture is difficult to exercise this muscle group. In contrast, imitating crabs walking sideways can make this muscle group stretch and contract continuously.

Sticking to exercise can effectively relieve the symptoms of leg and joint pain. At the same time, when people stride, they can also stretch their back muscles by twisting their waists to relieve back pain. "The friend explained.

I looked up a lot of information on the internet and basically found out the steps and essentials of practicing crab walking. It turns out that the crab walk looks simple, but it is very delicate to do. Before walking, spread your heels at 45 degrees, inhale slowly, and twist your knees slowly toward your toes. Then exhale and slowly step sideways, and the time to take a step is generally about 5 seconds. Of course, middle-aged and elderly people should choose their own pedaling frequency according to their own body, and don't start practicing too fast, so as to avoid muscle sprain or falling down because of poor coordination.

I practiced in the yard for a while and gradually felt the benefits of this sport. Every step I take, I feel my toes will involuntarily tilt up, and the inner muscles between my thighs and knees are in a tight state. After walking for about 3 minutes, my muscles will feel a little numb, which is a considerable exercise.

Gradually, I realized that crab walking is actually like the sixteen steps of square dance that old people often practice, because walking sideways is different from our usual walking. When taking the crab walk, you need to squat your legs slightly, keep your waist straight and move slowly. Every step, toes should be hooked up and legs should be raised, which is really effective in relieving the symptoms of low back and leg pain in the elderly. And practicing leg muscles is also stretching back muscles by twisting the waist.
