We have to keep the body in good health; we have to take care of what we eat and drink, and what we do.

Exercise till the mind feels delight in reposing from the fatigue.

Exercise is bunk. If you are healthy, you don't need it: if you are sick you should not take it.

The doctor of the future will give no medicine, but will involve the patient in the proper use of food, fresh air and exercise.

Exercise dissipates tension, and tension is the enemy of serenity. I found that I worked better and thought more clearly when I was in good physical condition, and so training became one of the inflexible disciplines of my life.

I have always believed exercise is a key not only to physical health but to peace of mind.
