Holding on to a chair or a wall at your side, step your feet out hip width or slightly wider and to a staggered stance mimicking striding forward. Close your eyes and slowly safely let go of the wall or chair support. Keep breathing deeply. Try to keep your balance. Notice how active your feet are in balancing, especially without the steadying help of your vision.
Do this both sides, and then try the tightrope version: repeat all of the same above except for the setup. Instead of hip width or wider, put the feet in line with each other directly in line or a few inches wide. This will be a greater challenge, so stay safe above all. Close your eyes and slowly release your hand from support and try to balance on the tightrope with your eyes closed. Keep breathing.
