The Pump, Occlusion Training, and How to Enhance Them

Posted on by

Call it instinct. Long before any breakthrough research on occlusion training, and its endorsement by many knowledgeable fitness professionals, bodybuilders sought to achieve the ever essential “pump” at each workout.

Ahhhhnald Schwarzenegger once compared getting a pump to having an orgasm.  …Can’t say I completely agree but, there is something about a good pump
that just feels right.

We’ve come to understand that the metabolic environment created from a skin ripping pump is essential to muscle hypertrophy.  We also know that there are few ways that are more effective in creating this environment than occlusion training (OT).

If you’re hearing of occlusion training for the first time here’s a brief explanation of what it is from one of the top researchers on the subject, Dr. Jacob Wilson:

Occlusion training involves wrapping a device like a pressure cuff or knee wraps around the top of a limb at a pressure sufficient to occlude, or obstruct, blood flow to the veins, but not the arteries. This way, the arteries continue to deliver blood to the limb, and the blood pools in the limb as the veins struggle to take it back to the heart. …During BFR, muscle cells reach a point where they are so full of fluid that they have to either burst or grow.

The second way BFR works is that the low oxygen level in a muscle during the accumulation of blood forces your body to recruit larger fast-twitch fibers, resulting in extreme growth.

Finally, when oxygen is low, lactic acid rapidly accumulates. This may sound bad, but studies show lactic acid by itself can increase protein synthesis!

If you want to learn and understand the underpinnings of occlusion training, also known as BFR (blood flow restriction training), you can find some very good research here.

I also highly recommend checking out The Use of Occlusion Training to Produce Muscle Hypertrophy and Practical Occlusion Training from Jeremy Loenneke.

The single biggest advantage of OT is the ability to train with lower intensity but receive benefit similar to training at high intensity.

You’ve seen those pendulum swings that have multiple metal balls attached, right?  And you know what happens the harder you swing the first one.  Every action has an opposite and equal reaction.

Exercise is no different.  High intensity is necessary to stimulate a hypertrophic response, but it also results in greater systemic stress on the body.  Over time, this accumulated stress makes recovery slow and difficult.

As a bodybuilder or anyone who wants to add muscle, maintaining a balance between exercise stress and recovery is a key factor in long-term success.  OT helps create the environment needed for muscle growth, minus the systemic stress.

That’s great!  But…

Is it really necessary to walk around the gym looking like a heroin addict
about to get his fix?

If strapping silly looking bands around your arms and legs will help you increase muscle, I’m all for it.

What I’m actually questioning is whether or not there may be an easier and equally productive way to get the same effect.  Unless you like portraying yourself as the Ultimate Warrior as you pace around your gym.

If we look at Dr. Jacobs description of what OT accomplishes it can be summarized as: restricting blood flow and oxygen to a working muscle and increasing the rate of lactic acid production.

By systematically applying an age old training technique, with some minor enhancements you can produce the same effect as OT without having to remember to pack your elastic wraps.

Not only that, but it is a much more effective way of restricting blood flow to the muscles of the upper torso, which has proven difficult in many of the OT studies.  Conversely, BFR of the lower body proves quite easy and effective since wrapping the upper most part of the upper thigh will directly impact the quads and hamstrings.

So, what’s the trick?

Well…some will call it partials, others will call it stage reps, or say it looks like “21’s”—at the IART we call it Zone Training.  A more systematized approach to performing short, forceful contractions over an exercises full range of motion.

A movement can be broken up into anywhere from 2-4 sections, or “Zones”, and you focus on performing very explosive contractions within that particular zone.  Check out the video below to see Zone Training is performed.

The lactic acid build up, blood engorgement, and discomfort you experience will be significant.

 And so will the pump you have, long after the set is over.  Everything about this method or rep performance works exactly like OT.

  • The rapid contractions over a short ROM traps blood in the muscles, cuts off O2 supply, and doesn’t allow lactic acid to dissipate.
  • It does not require maximal loads (50-70% of 1RM is often sufficient).  In fact, near max loads can diminish the effect since you want to concentrate on contracting the target muscle through the target ROM without tensing up outer lying muscles.
  • It results in very little systemic stress compared to typical high intensity training.
  • And did I mention, it’s painful.

One difference however, is that you are not starting with restricted blood flow but rather, building up to it.  For this reason sets may last slightly longer.  Typically 40-60 seconds for approximately 24 contractions in total.

For example, if you’re splitting a movement up into halves you would perform 12 reps per half.  If you were splitting it into thirds you would do 8 reps per zone.

[NOTE: It may be necessary to perform slightly more or less reps per zone depending upon your strength in each zone.  Also, you may opt to perform more than the recommended 24 contractions per set (i.e 40-45).  This can lead to an even greater pump but can be extremely painful.]

The initial zones should be performed short of momentary muscular failure so you can transition into the next zone without rest and enough strength to complete that zone.  It may take a couple of workouts to determine the proper weight load or exact number of reps for each zone.

There are unlimited combinations and methods of applying Zone Training, but traditionally it is best to start with the weakest part of the ROM and progressively move to the strongest.

The added benefit of doing it this way is that it flattens the exercise’s strength curve. This results in your muscles feeling more thoroughly worked from the point of origin to insertion.  The benefits of this is a different topic altogether.

As they say, there’s a method to the madness, and this is definitely the case with Zone Training.  Whereas 21’s, partials, or even stage reps are a way to “change things up” or performed as an afterthought, Zone Training is an entire method unto itself with specific directives for specific purposes.  The most notable of these purposes being blood flow restriction and creating a metabolic environment for muscle growth.

The Role of Muscle Maturity on Physical Appearance

Posted on by

There is an interesting phenomenon that has been developing for over a decade.  It is not something that would be noticeable to the average population nor have I come across many fitness professionals who have observed it either.  However within the natural bodybuilding community it has become abundantly obvious that more of today’s top level competitors are—for lack of a better description—older.

Bodybuilding has long been considered a young man’s sport yet…

We Have Seen an Increasing Rate of Winners and Top Competitors Be Men in their Late Thirties, Forties and even Fifties

The scientific explanations for this trend should provide hope for trainees and bodybuilders who believe their best days are behind them as well as younger bodybuilders who are frustrated by their inability to achieve a “harder” appearance.

First allow me to clarify that the only reason I believe we are seeing this trend mostly among natural bodybuilders compared to enhanced bodybuilders has to do with the judging criteria and preferred “look” of the athletes.  Whereas freakish muscle mass rules the posing dais in organizations that do not test for PED’s; natural organizations place greater emphasis on competitors level of leanness and conditioning (muscle hardness) relative to their muscle mass.

Muscle Maturity can Make a Major Difference

I remember starting my bodybuilding career as a young twenty-two year old and taking note of how most of the competitors who were placing ahead of me, but comparatively speaking were no more muscular or leaner, were almost always older.  My observation was often confirmed when I would talk with the judges afterwards and was told that although I had a good frame, symmetry and an overall appealing physique I just need more time for my body to mature and achieve the harder, grainy look of my elder counterparts.

Needless to say it’s a very frustrating piece of criticism to receive when you want to be your best now and are doing what you can to add more muscle and lose more body-fat.  Nonetheless the analysis of my “problem” was spot.

With each passing year I noticed my muscles taking on a different look. They were harder, fuller, and seemingly denser despite my competition weight and body-fat percentage being relatively unchanged. While some of these changes can be attributed to the addition of new muscle tissue and smarter dieting practices I can say with complete conviction that over certain periods the only gains I made were in age.

What Beef Carcass can tell us about Aging Muscles

Several animal studies support the above “aging” observation, providing insight into to how age factors into the hardened appearance of muscles.  The studies, which examined the characteristics of beef carcass slaughtered at different ages, revealed the most youthful carcasses were more tender than those from the most mature carcasses1, 2.

A 2006 study not only confirmed the coarser texture of mature cattle carcasses but also showed that mature cattle’s possess less intramuscular fat compared to younger and intermediate cattle3.    In humans however intramuscular fat does not naturally decrease with age, but it can be lowered or kept at bay through exercise since it (like glycogen) is a primary source of energy for working muscles.

Muscles Do Not Mature in the Absence of Weight Training

Another study showed that the rate of increase in the toughness of individual muscles with animal age was related to their connective tissue strength and that muscles which did not possess high connective tissue strength were unaffected by age, whereas high connective tissue strength muscles, trebled in toughness4.  If we took a cross-section sample of muscle from two men of the same age, one being untrained and the other with eight years of weight training experience, we would see—as expected—a marked difference in the quality, thickness, intramuscular fat and degree of muscle firmness.  This is why age alone is not responsible for a muscles “maturity”.

Being Thick Skinned is Good for Your Sanity, Terrible for Bodybuilding

There are two factors that determine epidermal thickness:  subcutaneous fat and collagen.   Reduction of subcutaneous fat is controllable through diet. Conversely, collagen, a protein that gives our skin its smooth appearance, does not appear to be affected by diet or exercise but exhibits a linear reduction with age in both men and women.

Interestingly collagen is also the main component of muscle fibers’ connective tissue.  With age the solubility of this protein decreases and in effect increases in the number and type of cross-links contributing to a muscle’s toughnes5.

With subcutaneous fat levels and muscle mass remaining constant we can see how the effect of aging on collagen directly impacts the hardened look of one’s physique and presents somewhat of an advantage to bodybuilders in their mid-thirties to upper forties. Though patience is required younger bodybuilders can rest assured that their continued commitment to resistance training will eventually result in a harder appearance.

Of Bodybuilders Who Achieve this Hard & Conditioned Look at a Young Age There are Certain Genetic Factors at Play

One of the most substantial is muscle fiber type.

As we know Fast Twitch (FT) muscle fibers contribute most to muscle hypertrophy.  Those able to develop their muscles to near maximum proportions early on or at a fast rate due to high proportions of FT fibers in effect stretch their skin to an extent that is not typical with slower or more modest muscle growth.

It’s not only muscle fiber type though.  Other genetic factors such as muscle belly length or high testosterone or growth hormone levels can also contribute to fast or above average muscle growth resulting in this stretching of the skin.

Combine this with an ability to reduce body-fat to low single digit percentages and these competitors are in the enviable position of achieving a look that is “beyond their years”.  And of course some individuals inherently have thinner (or thicker) skin as can be observed amongst various ethnic groups, a trait inherited from their ancestors whose bodies had adapted to the climate they lived in.

Training for Harder Muscles

Clearly resistance training has a direct effect on muscles firmness but whether or not certain training methods can influence the expediency with which collagen cross-links are formed and solubility decreased, requires further examination.   At present there are no studies to support claims that particular training methods can accelerate the hardening of muscle fibers and connective tissue and any such claims are pure conjecture.

Even if it were determined that increases or decreases in certain training variables (i.e., volume, frequency, intensity, load, rep performance) could expedite the hardening effect we would still need to examine the overall impact of implementing these changes on other aspects of muscle development, strength, tolerance and recovery ability.  At the moment our only course of action in achieving a more dense appearance is to implement training and dietary methods that maximize muscle development and fat-loss, and let time and nature determine the rest.
