“Begin by testing the limits of your equilibrium. If you can stand sturdily on one leg for a minute, cross your arms over your chest. If even that’s undemanding, close your eyes. Hop. Or attempt all of these exercises on the pillow, so that the surface beneath you is unstable. ‘One of the take-home exercises we give people is to stand on one leg while brushing your teeth, and to close your eyes if it’s too easy,’ Hertel says. ‘It may sound ridiculous, but if you do that for two or three minutes a day, you’re working your balance really well.’” [link]
