The Training Process: Why Most People Exercise But Never Actually Train
Summary: Training is a systematic, organised process designed to elevate performance to its highest possible level. Exercising is physical activity without that goal. The training process is governed by a series of principles of adaptation; overload, variation, specificity, reversibility, and individualisation and can be explained by three models: supercompensation, general adaptive syndrome (GAS), and the fitness–fatigue paradigm.
Key Takeaways
Training ≠ exercising. Training has a defined performance goal; exercising does not. Both are valuable, only one drives meaningful adaptation.
You have a genetic ceiling. Training is the process by which you realise your genetic potential, not break past it.
Five principles govern adaptation: overload, variation, specificity, reversibility, and individualisation.
Three models explain how you respond to training: supercompensation, general adaptive syndrome (GAS), and the fitness–fatigue paradigm.
The "zone of optimisation" the right training dose for an athlete on any given day is dynamic, not static. A coach reads it; a generic program ignores it.
Most people who walk into a gym are exercising. A much smaller group is training. The difference matters, and it sits at the heart of every successful strength athlete’s career whether you have decided to compete in powerlifting, you are coming back to the barbell at 55, or you simply want your body composition and strength to actually change after years of going nowhere.
Training can be defined as a systematic, organised process of preparation designed to elevate performance to its highest possible level. Exercising, by contrast, is physical activity without the goal of maximising performance. Both have value. Only one will get you the result you actually said you wanted.
This article unpacks the training process the principles that govern adaptation, and the three theoretical models that explain how your body responds to a well-organised plan. It is the foundation we use at MD Strength to write every program, from complete novices to elite athletes.
Why Genetics Set The Ceiling, And Training Decides How Close You Get
Sport performance capacity is built on a complex blend of factors that affect the athlete’s trainability, health status, skill, and coordination. The single largest determinant and the one no one wants to hear about is your genetic potential.
Every athlete has a genetic ceiling. Performance is highly individualised, and training is the process by which your genetic potential is realised. The point of structured training is not to break that ceiling; it is to get you as close to it as possible, without breaking you on the way up.
That sounds limiting, but it is actually liberating. Once you accept that your trajectory will not look identical to anyone else’s, you stop chasing other lifters’ programs and start asking what works for you.
What Are Exploitation And Optimisation In Training?
The primary goal of the training process is to prepare the athlete for the highest possible level of performance. This is achieved through two interlocking concepts.
Exploitation involves leveraging knowledge from a variety of scientific disciplines — physiology, biomechanics, psychology, nutrition, and motor learning — to inform what you do in the gym. In plain language, it means using what we already know about how the body adapts, rather than guessing.
Optimisation ensures the training process is structured in a way that produces the ideal psychological state and performance capacity. It involves finding the balance between too little and too much training load — volume, intensity, frequency, and density — and seeks to achieve the proper balance to produce the desired psychological, physiological, and performance responses (Bompa & Haff, 2009).
Put simply: exploitation is knowing what to do. Optimisation is knowing how much, and when.
How Does Training Work As A Dose–Response Relationship?
A useful frame is to treat training as a dose–response relationship. The training you undertake is the dose. The way your body handles it is the response.
Training stimuli sit on a continuum, with undertraining at one end and overtraining at the other. Somewhere on that continuum, for any individual at any given time, is a zone of optimisation training that is neither too little nor too much, but the right amount for that athlete’s current state.
The zone is not static. It moves based on the athlete’s psychological status, training status, training age, life stress, sleep, and nutrition, amongst other positive and negative factors. It is constantly in flux, responding to the training stimuli applied and the athlete’s perception of those stimuli.
A good coach is not someone who hands you the same program every block. A good coach reads where your zone is this week, and prescribes accordingly.
What Are The Five Principles Of Training Adaptation?
Adaptation is the process by which your body adjusts to its environment. The training load you impose is a powerful stimulus for adaptation, and the greater your ability to adapt, the greater your potential for performance gains.
Training adaptation is best managed by a well-organised periodised plan that considers five principles: overload, variation, specificity, reversibility, and individualisation.
1. Overload
A training load above what the athlete typically encounters is considered an overload. The most common ways to apply an overload are increasing volume, increasing training frequency or density, increasing absolute or relative intensity, or combining any of the above. Intensity can also be raised qualitatively by changing to a novel variation, or working through a different range of motion to expose the athlete to a stimulus they are unaccustomed to.
If the overload is applied correctly, the athlete adapts, achieves a performance gain, and shifts their adaptation threshold upwards. The right load both stimulates adaptation and reduces injury risk.
Get it wrong and you create one of two problems. If the load is excessive or overly varied, maladaptive responses manifest as reduced performance capacity excessive fatigue, overtraining, or what is sometimes called monotonous program overtraining. If the load is too low, a detraining or involution effect occurs and performance regresses. This second category is sometimes referred to as useless load. Plenty of commercial programs fall squarely into useless load.
The beauty of being a novice is that almost any structured stimulus will produce adaptation. The challenge of being advanced is that almost nothing will, unless it is targeted, hard-earned, and recovered from properly.
2. Specificity
Training adaptations are highly specific to the methods employed. The SAID principle (Specific Adaptations to Imposed Demands) tells us that training should be closely related to the performance target. The greater the specificity between the training activity and the sporting outcome, the greater the potential of training to affect performance. Specificity is, in essence, an issue of transferability.
Specificity has two layers. Metabolic specificity relates how the energy systems used in training match the demands of the sport. For a powerlifter, that means short, high-intensity efforts with full recoveries not 45 minutes of fluff. Mechanical specificity describes the relationship between the kinetic profile (force) and the kinematic profile (displacement, velocity, power, and rate of force development) of the training activities and the performance outcomes.
3. Variation
Variation is a core tenet of training theory because it is directly linked to the stimulation of training adaptations. The monotonous implementation of training dose tends to drive a plateau in performance and, in some cases, an outright reduction in performance capacity. The degree of monotony has been linked to poor performance and may also be linked to increased injury risk (Foster, 1998).
Variation comes in two flavours. Quantitative variation involves manipulating volume frequency and density and intensity, expressed as resistance, power output, or speed. Qualitative variation involves changing the exercise or focus of the session to vary the stimulus and direct the physiological response.
Both matter. Too little variation and you stagnate; too much, and you never accumulate the consistent stress required to drive adaptation. Whilst the balance is delicate, it is exactly what a periodised plan is designed to manage.
4. Reversibility
If there is inadequate training stimuli to either develop or maintain training adaptations, the adaptations you have built can be lost. This is often referred to as detraining, and it is best thought of as a negative adaptation a maladaptation rather than a neutral pause. Detraining can occur very rapidly if the training stimulus is significantly reduced or completely removed.
This is why "I will get back to it next month" almost never works. Your body responds to what you are doing now, not what you did six months ago.
5. Individualisation
Training needs to be tailored to meet the individual athlete’s needs their ability, potential, learning characteristics, and the demands of the sport. Several things must be considered: age and maturity. Training age and history, current psychological state, which is linked to both increased injury risk and a reduced ability to adapt, current work capacity, overall fitness level, injury status, and anthropometric characteristics.
This is why a generic 8-week challenge will never out-perform an individualised plan over the long term. The variables that matter most are inside the person, not on the spreadsheet.
What Are The Three Models Of Training Adaptation?
Three generalised theories can be used to understand how athletes respond to training interventions. None is perfect. Together, they form the conceptual scaffold every serious coach should know.
Supercompensation
Supercompensation describes the relationship between work and restoration that leads to physical adaptation and an elevation in the athlete’s preparedness the combined physical, psychological, intellectual, and mechanical readiness to train or compete.
It is typically depicted as a four-stage process. Phase 1 is the initial fatigue response to a training bout. Phase 2 is the compensation phase, where preparedness returns to baseline. Phase 3 is the supercompensation response, where preparedness sits above baseline. Phase 4 is the dissipation of that response often referred to as involution.
The practical implication: time your next stimulus during Phase 3, not in Phase 1, and not so late that you have already involuted. This is harder than it sounds.
General Adaptive Syndrome (GAS)
GAS, drawn from Selye’s (1956) foundational work on stress, presents four phases of potential response. The alarm phase is the fatigue response to a training stimulus. The resistance phase is where adaptation occurs and performance returns to baseline. Supercompensation follows, with an elevation in performance above baseline. Overtraining is the fourth and least desirable phase, where cumulative stressors result in reduced performance.
Importantly, training stress can be magnified by external stressors social, psychological, emotional, and nutritional. Life happens. External stress can extend the duration of the resistance phase and delay or blunt adaptation. This is why your coach should know what is happening outside the gym, not just what is on your spreadsheet.
Fitness–Fatigue Paradigm
The fitness–fatigue paradigm is, in my view, the most useful working model (Banister, 1991). It treats fitness and fatigue as two independent aftereffects of training that summate to determine preparedness. Fitness is the positive aftereffect. Fatigue is the negative aftereffect. Preparedness is what you can actually do today and is what is left when the two are added together.
The modified version of the model recognises that there are likely multiple independent fitness and fatigue aftereffects acting on the athlete at once. You can be carrying high strength fitness with high systemic fatigue, low aerobic fitness with low local fatigue, and so on. Good programming manages these effects deliberately building fitness where it is needed, and shedding fatigue at the right time so that preparedness is highest on competition day.
What This Means For Your Training
If you have read this far, you are already further into the theory than the majority of gym-goers. A few practical takeaways for students of the sport.
Decide whether you are exercising or training. Pick one and write the program to match. Stop chasing other lifters’ blocks your zone of optimisation is yours alone. Respect overload, variation, specificity, reversibility, and individualisation in that order. Track your preparedness, not just your sessions; fitness and fatigue both add up, and so does life outside the gym.
A well-organised periodised plan is what consistently delivers all of this. That is what a coach is for, and it is what we do at MD Strength every day from your very first time under the barbell, through to national and international Powerlifting success.
Frequently Asked Questions
What is the difference between training and exercising?
Training is a systematic, organised process of preparation designed to elevate performance to its highest possible level. Exercising is physical activity without that performance goal. Training has a defined target, a structured program, and progressive overload; exercising is movement for its own sake. Both have value, but only training drives meaningful, measurable performance adaptation.
What are the five principles of training adaptation?
The five principles of training adaptation are overload, variation, specificity, reversibility, and individualisation. Overload provides the stimulus, variation prevents plateaus, specificity ensures transfer to the sport, reversibility describes how adaptations are lost without continued training, and individualisation tailors all of the above to the athlete in front of you.
What is the SAID principle?
SAID stands for Specific Adaptations to Imposed Demands. It states that training adaptations are highly specific to the methods employed, so training must closely resemble the performance target. For powerlifters, this means the Squat, Bench Press, and Deadlift sit at the centre of the program, supported by accessory work that reinforces — rather than competes with — those lifts.
What is the zone of optimisation in training?
The zone of optimisation is the range of training load that is neither too little (undertraining) nor too much (overtraining) for an athlete at a given point in time. It is dynamic, not static, and moves based on training age, current fitness, life stress, sleep, and nutrition. A skilled coach reads where this zone sits each week and prescribes accordingly.
What is supercompensation?
Supercompensation is a four-phase model describing how preparedness changes after a training bout: initial fatigue (Phase 1), recovery to baseline (Phase 2), elevation above baseline (Phase 3), and dissipation (Phase 4). The aim of good programming is to deliver the next training stimulus during Phase 3, so that adaptations compound rather than wash out.
What is the fitness–fatigue model?
The fitness–fatigue paradigm (Banister, 1991) treats fitness and fatigue as two independent aftereffects of training that add together to determine an athlete’s preparedness on any given day. Fitness is the positive aftereffect, fatigue is the negative aftereffect, and preparedness is what remains when the two are summated. The model is the working logic behind every well-built peaking and tapering plan.
Can older adults follow a structured powerlifting program?
Yes. A structured, progressively overloaded barbell program delivered under qualified coaching is appropriate at any age, provided it is individualised to the athlete’s training age, work capacity, injury history, and health status. At MD Strength we coach lifters from their very first time under the barbell through to national-level competitors, including masters athletes.
