Strong toes prevent small twists and sprains
Socks with feet: Sit on a chair, pick up the socks on the ground with your toes, and move them to a place 12 inches (about 30 cm) away. Two feet take turns, and each pair has 5 pairs of socks.
Scratching towel with feet: Sitting on a chair, spread a towel on the floor in front, and then scratch the towel with your toes to make the towel look like an accordion.
Do this twice for each foot.
Balance: Fold the towel, stand on one foot for about 30 seconds, and use the muscles of the body to maintain balance until the calf and joint joints become sour.
Do this 3 times per foot.
