Stretching and Bending for Exercise – Strength Magazine – April, 1927

Many people instinctively stretch the first thing on arising in the morning. Probably they do not realize that it is a natural instinct and, probably, do not ask themselves why they do it. Few realize that they are doing just what every healthy animal does on awaking from sleep. Watch a cat, that has been sleeping in front of a fire, when it awakens. You will see it stretch first one leg and then the other. Oftentimes the cat will stretch the front feet as far to the front as possible and lower the back, stretching it to the limit.
