The Side Muscles – Strength Magazine – July, 1917

Of all muscles, we hear the least about the muscles of the sides. One authority tells you to develop the muscles of the chest, another teacher may specialize on the development of the muscles of the back, and still another may urge the development of the arms and legs, but we rarely hear of a man speaking of the importance of the side muscles.
