sit-up
Find a stool at home and sit on it in a standard sitting position. First, keep your waist straight, grab the edge of the stool with both hands, and be sure to grasp it. Then, lift your body with your arms until you leave the stool, and curl your waist to lift your lower body. Keep your hips curled up after leaving the stool. The time is right. You can adjust the time according to your current situation and repeat 5 groups. Each group requires that you can't persist, and each group has the same time.
2. One hundred
This action may be interesting. First, lie on the floor with your legs tilted upward, making an angle of about 120 degrees with the ground. Then get up and do belly roll. After reaching the highest point, keep your posture, straighten your arms parallel to the floor, and start swinging your arms up and down, counting the times in your mouth until the number of swings is 100. Lie on the floor and continue to do this action once.
catercorner
Kneel on the floor, slowly bend your body down, hold your arms straight on the floor, slowly lift your arms and legs diagonally, and keep the rest of your posture unchanged. Hold the posture for more than 5 seconds after lifting, and then slowly return to the initial posture. Continue to do this on the other diagonal, and the two diagonals cross 20 times.
4. Half-squat twist
Stand on the floor with your legs shoulder-width apart to prevent your body from shaking back and forth during rotation. Raise your fist to shoulder height, then squat down and keep your knees bent 90 degrees. Turn your body to the left to the maximum extent, turn back after turning, get up while turning, and continue to repeat this action on the other side for 30 times alternately. This action is very useful for muscle exercise on both sides of the abdomen and must not be ignored.
get up
Getting up from the floor is not the usual way! First find a towel and then lie on the floor, cross your legs and put the towel under a straight leg. Grasp both ends of the towel with both hands, straighten the leg wrapped in the towel upward, lay the upper body flat on the floor, climb up bit by bit with both hands, keep the waist strong, climb down bit by bit after climbing to the highest point, and resume the initial action. Repeat 10 times. Remember to crawl slowly while keeping your waist muscles tight.
