Isometric exercise is a concept and strength training technique where you are engaging your muscles and exerting force in a static position. The study resulted in the isometric training group improving faster than the sports training group on tests measuring increases in strength, endurance, coordination, and agility.īullworker took these findings and pioneered portable home fitness devices and the 7-second isometric exercise for the fastest strength gains using both contraction and extension movements involving a range of motion for enhancing all your major muscle groups. Baley put isometrics to the test with a class of college students at the University of Connecticut. Optimum results are attained with 5 workouts per week, but impressively, even one single weekly workout is sufficient to maintain your improvements attained. The study at the Max Planck Institute consisted of over 200 experiments for a ten-year period. Hettinger discovered maximum muscle growth can be attained by exerting 60% of existing muscle strength against a superior resistance for only 7 seconds once a day a remarkable fitness technique known as isometrics. Isometric exercises are science-backed techniques tested through international studies such as the below findings at the Max Planck Institute, one of Germany’s prestigious universities, and the University of Connecticut.ĭr.
