Core training? Isolate? Integrate? Just lift heavy? Draw-in? Brace? by Michael Boyle

Dr Stuart McGill describes the core structure as “a fishing rod held up by guide wires.” In other words, the spine is a flexible structure made stiffer or more stable by outside influences. McGill has also described the deep abdominal muscles as drawing strength from crisscrossed layers, much like plywood. Both analogies may help outline a picture of core training. McGill’s work is both interesting and compelling, and his books, Back Mechanic and Low Back Disorders, are must-reads for any strength and conditioning professional.
