Weider’s Confusion Principle

Have you ever wondered why Circuit Works works? And the logic behind it? You’d have to look no further than to Joe Weider and his confusion principle for the answer. Weider, known as the father of bodybuilding, came up with the concept that constantly changing your workout, shocks your muscles, and disallows your body from becoming accustomed to the exercises. The former Muscle and Fitness Magazine publisher coined the Weider System, which includes all of his “principles” dating back to the 1960s.

 The crux of the confusion principle involves constantly changing the variables in your workout. For example; the number of reps, which order you do different exercises in, how many reps you do, the length of your resting period, and even the angle at which you perform an exercise. This is why at Circuit Works we change up the different resistance stations each week. It is designed so your body and muscles do not become used to the workout out and your progress isn’t stalled or you don’t get bored. Research from Arizona State University shows that those who train using the muscle confusion theory compared to those who use linear periodization (progression of technique in a predictable way but with increase of difficulty) had a much better result. Some increased their bench press and leg-press strength by 100%. But just changing up your workout isn’t enough, you also have to be consistent and progressively building your load. In order to avoid muscle-building plateaus, it’s better to build efficiently with unpredictable movements rather than letting your body get used to repetitive moments. The idea is to keep the body guessing without completely changing the workout routine. So swimming one day and jogging the next is not the same thing. Switching-up your resistance training exercises so that you do similar exercises at different angles is ideal. Weider died on March 23, 2013 but his contributions to the fitness industry will live on in his legacy.
