Much of America did not have to worry about keeping fit 100 years ago. In those days, 40% of the population was working on farms, sowing, herding and moving. In the coastal cities, strong stevedores were loading and unloading ships without a container or stacking crane. Builders, lumberjacks and railroad men drove nails or sawed wood with their muscles, not power tools. In addition, for those doing the washing, cooking and scrubbing, that was a power workout though not too dainty. Every pick of the 8-pound iron that gave ironing its name (ironing the clothes) was a solid 8-pound weight training exercise. In those yesteryears, staying in shape was not an issue. Working out, was a phrase that would never have been understood in those days other than to mean going to work for a living.
