Ball inflation re: flats vs heels: what is recommended?
I use this ball at my work and my shoes go back and forth between flats and heels. I know my legs should be at a 90 degree but the picture shows the lady barefoot. What do you recommend for inflation for the ball? What effects will I feel if over inflated? and if underinflated?
