operational approach
0 1
Waist rotation: stand with your feet shoulder width apart, with your hands akimbo, rotate your waist clockwise and counterclockwise 1 time, and then rotate it alternately for 8 times from small to large.
02
Five-point support method: supine position, bend elbows and knees on both sides, support the head, feet and elbows at five points, and arch the waist hard (you can arch the waist with your palm). Repeatedly (according to personal physique, it is advisable not to be tired).
03
Three-point support method: After five-point support exercise, the waist muscle strength is better. You can hold your chest with your arms, support your head and feet at three points, and do arch exercises repeatedly (see five points for the amount of exercise).
04
Four-point support method: on the basis of the former, do arch bridge movement with four points of hands and feet as support and repeat it many times (see five-point support for the amount of exercise).
05
Hold your head up and chest out: prone position, straighten your upper limbs close to both sides of your torso, hold your head up and chest out, and repeat several times.
06
Straighten and lift your legs: The basic posture is the same as before, and you will raise your head and hold your chest straight and lift your legs repeatedly.
07
Raise your head, chest and legs (flying swallow style): The basic posture is the same as before, the abdomen is on the bed, and the head, hands, chest and lower limbs are raised together, repeatedly.
