Ankle circles
Lift your foot off the floor, then start rotating it at your feet 10 times inwards and outwards. Repeat the exercise 2-3 times per leg.
Resistance band
Fix a resistance bend around a chair or couch leg, then put one leg underneath the other and bend your knee a bit. Now, grab the bend with the toes of the top leg, then bend backwards towards your head. Slowly go back to the original position, then repeat the movement 15 times per leg. This powerful exercise will reinforce your calves and outer thigh muscles.
Toe games
While standing upright, curl your toes and try to grab the floor. To make things easier, put pebbles or a towel on the floor and try grabbing it with your toes.
Walking on balls
Put a tennis ball on the ground, then sit on a chair and put one foot over it. Push the ball all over your feet and enjoy the massage for 5-10 minutes.
