The action of aerobics
1. Waist and hip torsion

2. The shoulder arm moves around the ring
Stand with your feet together, raise your arms to shoulder height to form a T-shape, palm down, and rotate your arms around the basketball circle for 20 times. Then do it 20 times with your thumb down and your palm back. Then turn the palm up 20 times and turn the palm forward 20 times. If you want to increase the difficulty, you can do this: stand with your left foot for the first 40 times and stand with your right foot for the last 40 times.
3. Hip and leg stretching exercises
Stand on the ground, bend over and try to touch the floor with your hands. One knee bends, the other stays straight, and the knees on both sides bend alternately. Pay attention to keep your feet flat on the ground and your head completely down. You feel that you are stretching your cervical spine with gravity, and your spirit is completely relaxed. This exchange lasts 15 seconds.
Tiptoe exercise
Stand with feet at an angle, heels together, hands akimbo. Then try to stand on tiptoe, put it down, stand on tiptoe, put it down, and repeat this for 40 times. This action exercises the calf muscles.
Diet after aerobic exercise
After exercise, sugar, fat and protein in the body will be decomposed in large quantities, producing more acid. So you will feel backache and particularly tired-at this time, it is necessary to supplement alkaline food and adjust the balance of blood environment in the body. Of course, the acidity and alkalinity of food has nothing to do with taste, but with chemical properties. For example, oranges, plums, apricots and other fruits are sour, but they are typical alkaline foods.
What to drink? It is best to drink unsweetened milk, soybean milk, tea and fruit juice, or drink mineral water and boiled water. After strenuous exercise in summer, you can drink some light salt water properly, but the salt should not be too high, otherwise it will affect digestion. Nothing to drink? Acidic foods with high sugar content, such as cola, will aggravate the degree of soreness.
What to eat? Beans are a good choice, such as tofu, dried tofu and various bean products. Kelp is also a "leader" in alkaline food. You can also fry sesame soybeans, add ginger and a little salt, and brew with boiling water to quench your thirst. These are all good alkaline foods.
