Do Isometric Exercises Build Strength?

There are hordes of thoughts about the best method of strength training; what I will say is that your regimen should include something that builds your body from the inside out. And in terms of strength training, you’ve probably very rarely heard the word “isometrics” used often. Thus, one can only wonder, do isometric exercises build strength?

For me, isometric exercises build strength from the tendons, ligaments, and nerves out to the muscles. I do training that isolates individual muscles for maximal muscle fatigue, and training that involves large muscle groups for fatigue of the central nervous system. As long as your training does not neglect internal principles of strength (like bodybuilding training that focuses solely on muscle without long-term development of the tendons), it can be a part of what gives you stability.

I have found that isometric exercises build strength in a way that is much faster than many other methods of exercise training. First of all, I perform isometric exercises in the 7 Seconds to a Perfect Body style of training, which allows for maximal intensity and fatigue of all of the fibers in a muscle in 7-12 seconds. There is no sacrifice of effort because of the brevity of the exercise; in fact, the short time period for the exercise should make in the importance of maximal effort even more crucial to developing muscles and tendons of steel. This will allow your strength to improve tremendously.

The answer is in the tension. The tension and intensity of a contraction is the stimulus that produces new muscle growth. Weight lifting is simply using an external stimulus that causes your muscles to tense; because your body perceives the weight as heavy, it recruits more and more muscle fibers to move the weight. The greater difficulty your muscles have moving the weight, the more they fatigue and progressively build up. Isometric exercises force a maximal level of tension from the beginning, making your muscle fibers work overtime and fatigue in just seconds trying to move an immovable weight.

Furthermore, performing isometric exercises that combine muscle control with training large muscle groups allows for a stronger CNS response that builds your overall endurance and muscle size. Isometrics, without a doubt, build strength in ways that allow me to do things most people would not conceive as possible. Once you reach advanced levels of isometric exercise, bending steel bars, horseshoes, frying pans, even 500lbs girders like Alexander Zass, with just the strength of your hands and body becomes routine.
