# How to Recognize the Symptoms of Overtraining and What to Do About It
Anyone who exercises regularly knows the feeling of determination when they want to give their all. More training sessions, greater loads, shorter breaks – the logic of "more is better" seems bulletproof at first glance. But the human body works differently than many enthusiasts would like. There is a boundary beyond which training stops producing results and starts causing harm. This is called overtraining, and it is a surprisingly widespread problem – not only among elite athletes.
Overtraining is not just a matter of fatigue after a demanding week. It is a chronic condition in which the body does not get enough time to recover and gradually becomes exhausted on both a physical and psychological level. According to the American College of Sports Medicine, overtraining can lead to a significant decline in performance, hormonal imbalances, and a weakened immune system – the exact opposite of what athletes are striving for. Yet a large proportion of active people struggle with it without even realising it.

Signals the body sends
So how do you know if you are overtraining? The answer is not always straightforward, because the symptoms of overtraining are easily confused with ordinary fatigue or seasonal illness. The key difference lies in how long the symptoms persist and how they respond to rest. While normal fatigue after a demanding training session subsides after a day or two, overtraining deepens, and restless nights, irritability, and declining performance persist even after a relatively restful weekend.
One of the most common and at the same time most reliable indicators is a paradoxical decline in performance despite regular training. If someone has been working hard for months but their results are stagnating or even deteriorating, that is a warning sign. A runner who notices that a pace they used to handle comfortably now exhausts them should take note. Similarly, a strength athlete whose maximum weights are dropping despite consistent preparation should be on alert.
The physical symptoms of overtraining are quite varied. They include elevated resting heart rate, persistent muscle and joint pain, frequent infections and colds caused by a weakened immune system, sleep disturbances or, conversely, excessive daytime sleepiness. In women, overtraining can disrupt the menstrual cycle; in men, testosterone fluctuations may occur. This is therefore not a trivial condition – it is a complex physiological response of the organism to chronic overload.
The psychological aspect is just as important as the physical one. Loss of motivation to train, irritability, anxiety, feelings of hopelessness, or a sudden disinterest in a sport that previously brought fulfilment – all of these are part of the typical picture of overtraining. Swiss sports physician Beat Müller describes it aptly: "Overtraining is a state where the body says stop, but the mind has not yet accepted it." This internal conflict is very characteristic of overtrained athletes and can lead to a vicious cycle – the worse they feel, the harder they try to compensate for poor results through more training.
An interesting example comes from the recreational running community. Imagine a thirty-year-old woman who decides to prepare for her first half-marathon. She starts training twice a week, then three times, then every day, because she wants to be as prepared as possible. Three weeks before the race, she begins to feel tired, sleeps poorly, her knees hurt, and she has to force herself to train. She finishes the race in a worse time than expected, and instead of joy, she feels exhausted. That is overtraining in practice – not a dramatic collapse, but a quiet exhaustion of the organism that accumulates insidiously.
What to do about overtraining
Once a person recognises the symptoms of overtraining, the question arises of what to do next. The first and most important step is reducing intensity or completely pausing training. For many athletes, this is a psychologically demanding decision – accepting that a break is not failure, but a necessary part of the process. The length of rest required depends on the depth of exhaustion. In mild cases, one to two weeks of lighter activity is sufficient; in more serious situations, recovery may take several months.
Recovery does not simply mean lying on the sofa, however. Active rest in the form of walks, gentle yoga, swimming, or stretching helps maintain movement habits while also giving the body a chance to recuperate. A study published in the journal Sports Medicine shows that a combination of complete rest and light activity shortens recovery time from overtraining more effectively than passive rest alone.
Nutrition plays a crucial role. An overtrained organism has an increased need for nutrients, particularly protein for muscle tissue repair, complex carbohydrates for replenishing glycogen stores, and healthy fats for hormonal balance. Many athletes, in their pursuit of results, underestimate their caloric intake – they eat less than their body needs during intensive training, thereby deepening the overtraining. Adequate intake of magnesium, zinc, and vitamin D additionally supports neuromuscular function and immunity. Quality supplements from natural sources, such as products from the range of adaptogens or mineral complexes available in health lifestyle online shops, can support recovery, but cannot replace a fundamental change in training approach.
Sleep is the most powerful recovery tool at our disposal. During deep sleep, the body produces growth hormone, repairs micro-traumas in the muscles, and consolidates neural movement patterns. Seven to nine hours of quality sleep per day is not a luxury for overtrained athletes – it is a therapeutic necessity. If sleep remains poor even after reducing the training load, it is worth considering sleep hygiene: a regular bedtime, a dark and cool room, limiting screens before bed, and evening rituals that promote relaxation.
Equally important is managing stress outside of training. The body does not distinguish between physical stress from training and psychological stress from work or personal life – both draw from the same recovery capacity. An athlete going through a demanding period at work or in their personal life should automatically reduce their training load, because their overall stress capacity is already stretched. Meditation, breathing exercises, or time spent in nature can contribute significantly to overall recovery and the reduction of cortisol – the stress hormone that tends to be chronically elevated during overtraining.
How to prevent overtraining
The best treatment for overtraining is, of course, prevention. And that rests on several simple but fundamental principles. The first of these is training periodisation – the deliberate alternation of intensive and lighter training blocks. Professional athletes are well acquainted with this approach, but recreational exercisers often ignore it in favour of constantly pushing for performance. Incorporating one lighter week after every three to four demanding weeks significantly reduces the risk of overtraining.
Monitoring your own body is another key element. There are a wide range of tools available – from a simple training diary to smartwatches measuring heart rate variability (HRV) – that can help detect signs of overload early. Resting heart rate measured every morning is one of the most accessible indicators: if it is consistently five or more beats higher than usual, that is a signal that the body has not yet completed its recovery.
An adequate number of rest days must not be overlooked either. Every training plan should include at least one to two days of complete rest per week. This applies even to enthusiasts who feel they "cannot afford" to miss a training session. Paradoxically, those who allow themselves rest achieve better results – because adaptation to training occurs precisely during recovery, not during the exercise itself.
It is also important to listen to your body without judgement. Sports performance culture sometimes promotes the idea that pain and exhaustion are signs of progress – "no pain, no gain." But there is a fundamental difference between productive effort and destructive overexertion. Learning to recognise this boundary is one of the most valuable skills any athlete can develop, whether they compete at the Olympic Games or simply run in the park three times a week.
Overtraining is not weakness or failure. It is a natural response of the organism to an imbalance between load and rest. The body is simply saying that it needs more care – and listening to it is not only wise, but in the long-term perspective, the only path to sustainable health and athletic performance.
