Few have contributed as much to our understanding of the relationship between exercise and health as Jan Helgerud and Jan Hoff.This is the story of the two researchers who developed the revolutionary and remarkably simple training method known as the Norwegian 4 x 4 method.Whether you are an elite athlete or a patient, four intervals of four minutes or four times four repetitions in strength of intensive effort hold the key to improving both health and performance.The book explains the science behind the method and tells the story of how it helped revolutionize the training of star such as Marit Bjørgen, as well as top clubs like Rosenborg, Celtic, Real Madrid, and Barcelona with players like Cristiano Ronaldo and Lionel Messi.Over the past twenty years, Helgerud and Hoff have also made groundbreaking discoveries about how crucial high-intensity training is for achieving a longer and better life in patients with heart diseases, stroke, COPD, MS, and other autoimmune diseases — and for health and quality of life regardless of individual circumstances.The book includes a twelve-week endurance and strength training plan suitable for all levels — from patients to elite athletes.
