That is the way it is with our bodies; our muscles and joints should be bent and stretched every day to take the kinks out, and keep them strong and flexible.
The best way is to tune up every morning for just a few minutes before you put on your clothes, and then again at night to rest the tired parts and exercise the parts that have not been used, so you can even things up.
The Right Position
First of all try to stand in the right position.
Stand with the feet side by side, a few inches apart and pointed straight ahead. Many people think you should turn out your toes because they think it looks better. This is not natural. If you stand on a step with one foot even with the edge, and let the other foot hang over the step below, it will hang parallel with the foot you are standing on. That is the way it is meant to go, and people who turn out their toes do so much walking sideways that they have to travel much farther than if they kept their feet pointed in the direction they want to go.
Then your legs should come up straight from your ankles; don't stand either on your heels or your toes, but right over the highest part of the arch, which is the strongest part, and best fitted to bear your weight when you are standing still, and brings your hips up to just the right place to hold your body.
