First lie down, with your feet slightly open and your hip muscles tightened. Put your hands behind your head and tilt your toes inward. Exhale and lift your feet (about 10 cm from the ground). Raise your head with your hands and stretch your neck. After fully stretching, take a breath, keep it for half a minute, restore the original posture, and repeat it 8 times.
