The theory of supercompensation: Strength training frequency and muscle gain

Average toughness coaching has a amount of well being benefits, and is viewed by many as an crucial component of a normal lifestyle that approximates that of our Stone Age ancestors. It increases bone density, muscle mass, and improves a quantity of overall health markers. Carried out properly, it may lessen body excess fat percentage.

Normally 1 would anticipate some muscle gain as a result of energy education. Gentlemen seem to be keen on upper-entire body gains, whilst girls show up to favor lower-entire body gains. But, numerous individuals do power education for a long time, and encounter little or no muscle obtain.

Paradoxically, individuals men and women encounter key energy gains, both gentlemen and girls, especially in the first number of months after they begin a energy instruction software. Even so, these gains are because of largely to neural adaptations, and arrive with out any substantial obtain in muscle mass mass. This can be irritating, specially for gentlemen. Most guys are after some apparent muscle mass gain as a outcome of energy instruction. (Regardless of whether that is healthful is another tale, especially as one particular will get to extremes.)

Following the original adaptation period of time, of “beginner” gains, usually no toughness gains take place with no muscle mass gains.

The culprits for the lack of anabolic response are typically thought to be minimal stages of circulating testosterone and other hormones that seem to interact with testosterone to encourage muscle mass progress, this kind of as expansion hormone. This prospects several to vacation resort to anabolic steroids, which are medication that mimic the effects of androgenic hormones, this kind of as testosterone. These medications usually increase muscle mass, but have a number of damaging limited-expression and lengthy-phrase aspect consequences.

There would seem to be a better, significantly less harmful, resolution to the deficiency of anabolic response. By means of my study on compensatory adaptation I typically seen that, underneath the appropriate circumstances, folks would overcompensate for obstacles posed to them. Power coaching is a type of obstacle, which ought to generate overcompensation beneath the appropriate situation. From a organic point of view, one would anticipate a comparable phenomenon a natural solution to the lack of anabolic response.

This resolution is predicted by a concept that also points out a deficiency of anabolic reaction to power coaching, and that unfortunately does not get sufficient interest outside the house the academic study literature. It is the concept of supercompensation, which is discussed in some detail in a number of higher-top quality college textbooks on toughness training. (As opposed to well-known self-support books, these textbooks summarize peer-reviewed educational research, and also provide the references that are summarized.) A single example is the superb book by Zatsiorsky & Kraemer (2006) on the science and practice of strength education.

The determine beneath, from Zatsiorsky & Kraemer (2006), shows what takes place in the course of and soon after a strength instruction session. The stage of preparedness could be witnessed as the load in the session, which is proportional to: the quantity of workout sets, the excess weight lifted (or resistance overcame) in each and every set, and the number of repetitions in each set. The restitution period is primarily the recovery period, which have to incorporate loads of relaxation and proper nutrition.


Observe that toward the conclude there is a sideways S-like curve with a initial stretch previously mentioned the horizontal line and another beneath the line. The very first extend is the supercompensation extend a window in time (e.g., a 20-hour interval). The horizontal line represents the baseline load, which can be seen as the baseline power of the individual prior to the physical exercise session. This is the place factors get tough. If 1 workouts again within the supercompensation extend, strength and muscle mass gains will probably occur. (Usually obvious upper-physique muscle mass acquire transpires in guys, since of increased levels of testosterone and of other hormones that seem to interact with testosterone.) Working out outside the supercompensation time window might lead to no achieve, or even to some decline, of both energy and muscle.

Timing power education periods appropriately can above time guide to considerable gains in toughness and muscle (see center graph in the figure beneath, also from Zatsiorsky & Kraemer, 2006). For that to come about, 1 has not only to regularly “hit” the supercompensation time window, but also progressively increase load. This have to take place for every single muscle group. Energy and muscle gains will arise up to a level, a level of saturation, soon after which no even more gains are attainable. Men who attain that point will invariably look muscular, in a far more or less “natural” way based on health supplements and other variables. Some men and women seem to obtain toughness and muscle very very easily they are often referred to as mesomorphs. Other individuals are difficult gainers, occasionally referred to as endomorphs (who have a tendency to be fatter) and ectomorphs (who are likely to be skinnier).


It is not straightforward to determine the ideal recovery and supercompensation intervals. They differ from man or woman to individual. They also vary dependent on varieties of exercise, figures of sets, and numbers of repetitions. Nourishment also plays a part, and so do rest and anxiety. From an evolutionary point of view, it would look to make feeling to work all major muscle mass teams on the very same day, and then do the exact same work out right after a particular recovery interval. (Our Stone Age ancestors did not do isolation exercises, this kind of as bicep curls.) But this will almost certainly make you seem more like a powerful hunter-gatherer than a modern bodybuilder.

To recognize the supercompensation time window, 1 could use a trial-and-error method, by making an attempt to repeat the identical exercise following different restoration occasions. Primarily based on the literature, it would make perception to begin at the 48-hour time period (1 total working day of relaxation in between sessions), and then move back again and forth from there. A sign that 1 is hitting the supercompensation time window is getting to be a tiny more powerful at each exercise, by carrying out a lot more repetitions with the exact same weight (e.g., 10, from eight in the earlier session). If that occurs, the bodyweight should be incrementally increased in successive periods. Most research advise that the best selection for muscle mass obtain is that of six to twelve repetitions in every established, but with no sufficient time underneath rigidity gains will confirm elusive.

The discussion over is not aimed at professional bodybuilders. There are a variety of variables that can impact power and muscle mass acquire other than supercompensation. (Still, supercompensation seems to be a “biggie”.) Things get trickier above time with qualified athletes, as returns on effort get progressively smaller sized. Even all-natural bodybuilders seem to benefit from various methods at various levels of proficiency. For instance, changing the routines on a standard foundation appears to be a very good concept, and there is a science to carrying out that appropriately.
