The Optimal Training Program?


Ask 10 people what they believe to be the optimal training regimen and you'll likely get 10 answers (maybe 11, if one person is indecisive). The true question: is there an optimal training regimen? It depends on who you ask.

The high intensity training (HIT) proponents say that one set to failure is all that is necessary for optimal growth, while others recommend using periodization where the number of sets, rep ranges, etc actually varies.
The truth is that both types of training can be beneficial; it really depends on your goals, time, training history, and experience.


Many of you are probably familiar with the late Mike Mentzer, who was probably HIT's most vocal leader. His writings were more on the extreme ends of HIT, whereas others recommend more of a balance between both lifting protocols (e.g., sometimes reduce the volume, but not to the extreme of training just a few sets for an entire body part every few weeks like Mentzer recommended).

Many well respected bodybuilders (e.g., Casey Viator, Dorian Yates, Lee Labrada, and of course the Mentzer brothers themselves) have also touted the benefits of a HIT program vs. high volume training regimens. So let's delve into some research as to which protocol may be more beneficial for your specific goals and needs.


What Is Better Suited To Your Goals?


One review published recently reviewed the available research on resistance training and the effects of various protocols. It is difficult to compare many of these studies because they all use different exercises, protocols, etc. Therefore, many assumptions are made when interpreting this area of research.

However, many similarities arise from these studies, allowing researchers to draw sound conclusions and not make leaps that are too far off the beaten path.

Number Of Sets:
First, keep in mind that the number of sets is just one component of an overall training protocol.
Exercise Selection:

It is also crucial to consider the exercise selection, training speed, goals, training history, nutrition program, age, etc.
So while the focal point of HIT vs. Periodization is the number of sets, actually looking deeper you'll see that there's more to it than that.

Since most individuals over train, cutting back on training frequency and volume may be "just what the doctor ordered" when trying to add some variety. To add a little personal touch to this; I have experimented with HIT in the past. I was surely one individual who was overtraining.


Personal Experience


I was young and nave and thought that the more time I spent in the gym, the better. This is a horrible mistake that many novice lifters (and seasoned veterans) make.

With HIT, my strength exploded through the roof on every movement; I was training 2 times per week for literally 15 minutes/session maximum. However, I ultimately hit a plateau and just like all programs, my body grew accustomed to that protocol - it was time for some variation.


Break The Plateau


This plateau is not surprising and explains why the folks in the "periodized camp" recommend varying the program. Neurologically, the body needs "confusion" for lack of a better term and varying aspects of your program offers just that.

So why did my strength skyrocket while on HIT? I was overtrained and not resting or eating enough for recovery. The food aspect of my lifestyle didn't change, and training with such limited frequency allowed my body to recuperate from the 6 day/week protocol I was previously performing.

My little experiment taught me to train less frequently than I was and to vary my training protocols more often.


Pros And Cons Of HIT Training


Here is a very brief list of pro's and cons of HIT Training:

Pros
Allows body to recover
Offers variation from current protocol
Short workouts are good for time restraints
Cons

Does not offer enough variety to workouts
Not recommended for beginners as training to failure could be dangerous if one is not familiar with resistance training.
This may be too strenuous for beginners unfamiliar with resistance training.
Only focuses on strength with limited carryover to activities that may require more muscular endurance.
The moral of the story is that all programs will work for some time. The reason for variety is that our bodies quickly adapt to what we give them; always do 10 pushups and never shoot for more means you are not challenging your body. If you have never tried

HIT, give it a whirl for a change. I can guarantee that many of you out there are over training. Go ahead and take one week off; you'll more than likely come back to the gym stronger than ever and ready to move some iron.
