Learn how to use muscles in your body correctly. The theory was discovered by Dennis Denlinger who studied engineering as part of earning a degree in Architecture from Carnegie-Mellon University.
The book tells how to use your five springs in the neck, upper back, lower back, shoulders and feet. It also tells how other systems of muscles work. All this is in simple language with many drawings and photographs as well as experiments you can do.
Denlinger researched the location of muscles in the doctors bible: "Gray's Anatomy." He then applied engineering basics to determine exactly how they should operate. He did the research to handle his own physical pains when doctors were unable to help.
