Exercise Workout Ball Sizing Tip

When in doubt about exercise ball sizing, it is safer to choose a larger size. You always have the option of inflating the ball less. Five foot three using a 65 cm ball? No sweat, just fit the exercise ball using the 90 degree rule in sitting. An under-inflated ball will not be as firm, but it will function just fine.
