Adequate exercise will strengthen the muscles and skeleton. We should strive for good posture until it becomes a regular habit. But an erect bearing requires an attitude of adequacy and self-esteem. We should walk tall like a thoroughbred, not arrogantly, but in recognition of the value and dignity of human life. Every part of the body is made for action.
Activity tends to life, inactivity to death.
Doing nothing is the nearest thing to dying. Far more people die from want of exercise than from over fatigue. It would be difficult to sufficiently laud its many benefits. Calisthenics exercise is the stretching type. It improves the posture, relaxes the body and prepares for more vigorous activity.
