Mind your sensations in the foot and work barefoot if you can. It helps.
Stand up and close your eyes. Breathe and check that your shoulders and hips are relaxed and lift one leg in the air. Do this without shifting the rest of the body and do this with both legs a few times. Now Draw the numbers in the air using first your toe and than your knee from 1-10 and do this in the front and in the back. If you have a friend to check your form on this it will be also entertaining 🙂 Now place a chair or a box and walk toward it. As you meet it continue to move so there is no impact and you stay upright though without tensing to do so. Next take a stick or have a partner sweep and stab with the ends and you need to keep breathing and move with it to come closer to the person working with you. You can also do this by yourself but will less surprise.
