What is symmetry?
Symmetry refers to the qualities of balance, proportion, shape and classical aesthetics. It was first described by the Greek philosopher Pythagoras, who explained it in terms of mathematical relationships (which were also used to construct Greek temples). Leonardo DaVinci later expanded on and explained these concepts by way of his "Canon of Proportions" (also known as the "Vitruvian Man"). This illustration depicted a man standing with his arms outstretched within a circle and a square.
The perfectly symmetrical physique is often described as the "X" shape.
The top of the X represents broad shoulders, the "V" in the top half of the X represents a wide upper back, narrowing into a small waist with small hips; and the bottom half of the X represents long legs with a flowing outer quad sweep, full calves and upper thigh muscles that seem to connect directly into the waist.
When you think of those who have achieved such classical proportions, they are few in number and include such elite company as Steve Reeves, Frank Zane, Bob Paris, Francis Benfatto, and Lee Labrada.
