Leg movement back and forth: lie on your back, put a square towel or pillow towel under the coccyx, with your legs facing each other, and then slowly lift your legs. Legs together, slowly fall, legs bent into frog shape, feet left and right apart, restore frog shape, feet together, lift legs, open like the first action. Repeat this action 20 times.

Leg up and down movement: prone, put your head on your hand, lift your leg up about eight inches from your hip, stay, bend your leg to your knee for five seconds, keep your calf vertical, stay, slowly lower your leg and restore to its original state. Repeat this action ten times.

Spread your legs like wings: sit on the floor with your hands akimbo and spread your legs until you feel nervous, but don't be too nervous to avoid hurting your legs. Lift your right leg six inches off the ground and don't lean forward. Slowly move your right leg to your left leg and keep it there, but don't touch the ground. Keep your legs at a certain distance from the ground and return to their original state. Do it ten times on each leg.

Double kick: sit up straight with your hands akimbo and your left leg bent. Lift your legs eight inches off the ground, and then stop. Lift your right leg eight inches, stop and keep your back straight. Drop your left leg eight inches, stop, and return to its original state. Take the right leg first, then the left leg. Do it eight times on each leg.

Stand with your legs apart: stand up straight, raise your arms to shoulder height, and stand with your feet at a 45-degree angle. Keep your arms still, lift your right knee to your right elbow and don't lean forward. Return to the original state, kick your right leg, touch your right foot or barefoot with your right hand, keep your legs straight and relax your feet. Take the right leg first, then the left leg. Relax at first, don't make your muscles tense or your ligaments tense. Do this ten times on each leg.
