Why does The Pettibon System put so much emphasis on muscle rehabilitation, especially isometric exercise procedures?
Spinal muscles are made up of two types of fibers: phasic and postural. Most muscles contain both types of fibers but one can be predominant within a muscle. Kinetic exercises like those used in gyms work for phasic muscles. They’ll gain strength and endurance within 90 days. Postural muscles require exercising eight times longer. And they respond best to isometric exercise.
