Heavy Duty Training- Why it Will Not Work For You!

Anyone who has been in gyms long enough has come across Mike Mentzer’s system of heavy duty training at some point. Mike Mentzer, Mr. America, Mr Universe (with perfect score) was an extremely talented, massive and yes, intelligent bodybuilder.
IN his early career, he followed the school of Schwarzenegger and Weider, which was a high volume approach. This way of training brought him an immense amount of mass and density, as seen in the photo. After the infamous 1980 Mr. Olympia, Mike retired from competing and started researching training and nutrition.

In the late 70s /early 80s it wasn’t uncommon to train 4 hours a day and consume 500 grams of protein a day (yes, I did follow this routine when I was 17…hey, I lived in rural Germany and there was no internet, so please forgive me).
Unsatisfied with the gains of the average non-steroid assisted trainee, he became convinced that the majority of people were over trained and drastically shortened his and his clients’ workouts.
In conjunction with Arthur Jones, he created his system of High Intensity Training or HIT. Basically, the trainee trained infrequently, 3-4 times every 2 weeks and did only one set beyond failure. He also added drop sets, negatives, partials etc.

There are many variations of heavy duty training. Dorian Yates, who is said to have been a heavy duty trainee, used in fact a much higher volume than Mike Mentzer ever prescribed.

Mike Mentzer became the somewhat anti-Arnold, anti-volume guy and spent 20 years of his life educating people about his style of training. He wrote several books on it (I highly recommend “Heavy Duty), made training videos etc. In fact, he died in the midst of a DVD shoot in 2001 due to heart failure.

While this philosophy looks great in theory, there are several problems with it. First off, it is impossible to always train with maximum intensity. Mike is said to have used amphetamines to keep his training intensity high. The problem with that approach is that it will overload the CNS and lead to burn out. Remember, muscles recover quicker than the nervous system.

Secondly, the average person does not have sufficient neuro-muscular efficiency to reach all muscle fibers in one set. In fact, we only use about 10% of all available fibers per set. Hence, 2 or more sets are needed, the science is pretty clear about it. Thirdly, constantly training at maximum intensity makes you very injury prone; just ask Dorian Yates.

Does this mean that Mentzer was all wrong? Not at all. He was the the first to point out that the majority of athletes do not sufficiently recover, restricted training to 60 minutes and he gave us negative reps.

If you are visually incline, here is a video I made in regards to this topic. https://youtu.be/OF6Efwp6wcI

All the best !

Tried heavy “strength” training without preparing with high-volume hypertrophy training first- shoulder, hip and back injuries followed! Thanks for the info!
