It is very good exercise and can promote people's blood circulation. People can sit on their knees, holding their ankles with their hands and their feet slightly off the ground. Inhale, one leg is raised and straightened, the other leg is tilted to the abdomen, and the spine naturally stretches. Exhale, bend your knees and fall back to the original state. Inhale and practice alternately.

Triangle extension:

Spread your legs twice as far as your shoulders, inhale, lift your arms sideways, turn your right foot back 90 degrees, and your left heel 15 degrees. Exhale, the spine drives the whole upper body to bend horizontally to the right to reach the limit. Touch the instep with your right hand, head up, and follow the line of sight with your left hand up. Keep breathing deeply for six times. If people can do this action often, it can promote blood circulation.

Camel style:

Kneeling, knees slightly apart. Hands and hips naturally hang down beside your body and straighten your spine. Hold your hips with both hands, inhale, gently push your pelvis forward, tighten your hip muscles, and slowly bend your upper body backwards. First, touch the heel on the same side with one hand. Exhale, keep up with the other hand on the same side of your foot, relax your head backwards, and exert as much force as possible on your waist and chest. Keep breathing evenly.

Warm reminder: If people can practice these movements often, it will bring many benefits to people's health, especially in cold winter. If people can practice yoga often, it will promote blood circulation, speed up metabolism and help people get calories. Especially for people with cold hands and feet, it is also very beneficial to practice yoga properly.
