    muscle confusion isnt something new! athletes have been training this way for a long time. this would be basic knowledge for anyone who has studied the human body or has any interest at all in weight training!

      We know, there was a little glitch in our Yahoo post. But muscle confusion is definitely new to a lot of people, and many who read our site are just getting starting with training programs. Thanks for bringing it to our attention Josh!

    Josh is absolutely right.

    Muscle confusion used with weight training is an old idea, and is simply being re-treaded by John Romaniello and others. It was originally coined by the founder of ‘Muscle & Fitness’ magazine, (and trainer of Arnold Schwarzenegger), Joe Weider. He calls it the “Weider Muscle Confusion Principle” (Google it if you need proof.)

    Anyone treating this like a new fitness craze is ignorant of the history of weight training. I have been using muscle confusion for over 25 years. (I’m 47 now.)

    Anyone who talks about ‘muscle confusion’ and does not mention Joe Weider in the same sentence is stealing from him and not giving him credit. How would you like it someone used portions of your articles and blog without giving you credit?

      Thanks for taking the time to make a comment and share your opinion. As Chelsea said, this type of training is very new for a big portion of our readership and if you look at the reaction to it elsewhere (Yahoo, US News, etc) you’ll see that many people didn’t know anything about it and really loved the article. I don’t believe their being uninformed can be labeled as ignorance.

      Also, the reality is that these new programs are relevant to the conversation now. People reading the sites that we write for aren’t generally looking for a history lesson, they want to hear News. Not to take anything from Jon Weider, we’ve read a lot of his research and methods and he’s obviously an industry leader, but a failure to mention someone is VERY different than stealing from them.

      Those are some pretty strong accusations that seem unnecessary to me considering the tone and audience of the article. Please read it the way it was intended and not as a ploy to take credit from anyone. That’s not how we roll around here.

      Thanks again Mark for making yourself heard!

    With all due respect, Ryan, I have worked for many years as a professional journalist, and failing to mention the original creator of a popular exercise program is allowing Tony Horton to get away with stealing. (Your article claims that he coined the term “muscle confusion” and that is not even close to true.) As a journalist, you have a duty to publish facts, and the article has still not been edited to show them.

    Also, you are putting words in my mouth by suggesting that I was calling your readers ignorant. I was only referring anyone who did not research the background of a commonly used phrase and term in weight training before writing about it — or passing it off as an editor.

    I would concur with the previous comments. Been haunting gyms for nearly 40 years. To write such an article without crediting Joe Weider relative to “Muscle Confusion Principle” while inferring credit to anyone else by omission of that fact is at least irresponsible journalism…..

    CB, have you ever heard of Google?

    1. Ryan

      Please be respectful with your comments. We love discussion but snarky comments aren’t necessary. We’ll look into the information behind the article and make any corrections that may be necessary.

  5. Mark Hill

    Well, I’m glad to see that the article has now been changed and rewritten, with the inaccurate information removed. (Though some credit to Joe Weider still seems fitting.) Thank you for listening and editing this.

    P90x has been around for a long time. I bought mine way back in 2005.

    Muscle confusion isn’t a new concept -and is much easier than most experts make it. The problem many are making at the moment is switching their exercises over before their muscles have gotten a chance to learn a movement. Change only needs to happen every 3-6 weeks and then it can be subtle. Switch up the reps,/switch up the tempo/ switch from bilater to unilater exercises (single arm rows instead of 2 arm rows) is all it takes to create the necessary change.

    Do a a standard full body resistance workout 3x a week for 3 weeks. Start at 2 sets of 15 reps with a 2/0/4/0 rhythm.

    Next 3 weeks, change to 3 sets of 12, change the rhythm to 1/2/6/0.

    The next 3 weeks, change to 5 sets of 5 with a rhythm of 1/2/4/2.

    After the first 3 weeks, if you can complete every rep of every set increase your weights. Muscle confusion achieved. (our muscles are not that smart).

    Switch from single exercises to supersets or supersets to circuit style. Again, muscle confusion achieved.

    Wow! Lots of passionate feelings about muscle confusion! Truth is, most people only associate the term with P90x. And not out of complete ignorance- as the average person does not have a broad knowledge base about strength training and does own a tv with P90x infomercials. To that end I think this is a relevant helpful article to explain terminology that is new to the masses.

    We have been designing “Muscle Confusion”routines for quite some time now. I would guess it has been a year or more since we did the same routine. I think it is really cool to have the ability to change up and have new and exciting routines every time you train. We started a blog at JoelseventyTwo.blogspot.com that shows sample routines, videos, etc.

    You can not still an ‘idea.’ If that were the case, journalists would be out of business!
