The concept of rest might seem counterintuitive to achievement, but science tells us it’s a critical component of progress. Rest days are not just a luxury; they are a necessity for muscle recovery, energy replenishment, injury prevention, and the prevention of burnout.
The ideal number of rest days can vary greatly among individuals, raising questions influenced by factors such as personal fitness levels, training intensity, and individual health goals. Expert guidance, while varied, provides a foundation for understanding one’s personal rest needs in the context of physical activity.
Recognising the need for an additional day off can be the key to sustainable training; it’s visible in the signs our bodies and minds exhibit, like stress, sleeplessness, and persistent soreness. The actions one takes on these rest days, whether engaging in low-impact activities or simply allowing the body to recuperate, can set a trajectory for enhanced performance and well-being.
Why rest days are important
In the world of fitness and exercise, the emphasis is often placed on the more, the better. However, incorporating rest days into your fitness regimen is just as crucial as the workouts themselves. Rest days serve multiple purposes that benefit your overall health, biological functions, and progress towards fitness goals.
Muscle recovery and repair
Rest days are fundamental for muscle recovery and repair. Contrary to popular belief, muscle fibres are not built during exercise but rather during periods of rest.
After a day of weight training or intense workout, microscopic tears form within the muscle tissue. It’s during the recovery period that the body works to repair these micro-tears, leading to muscle growth and increased muscle mass. Additionally, sleep plays an important role in this process, as growth hormone is predominantly released during this time, aiding in the repair and growth of the muscle tissue.
Energy restoration
The restoration of energy is another vital benefit of having rest days per week. Your body’s glycogen stores, which act as your main source of energy during high-intensity workouts, are depleted during exercise. These energy stores need 36-48 hours for full replenishment, which can only be achieved through adequate rest.
Energy restoration isn’t just about glycogen, though; it also entails the repair of damaged muscle fibres, fortifying them to be resilient and robust. This energy restoration is essential to avoid both physical and mental burnout.
Injury prevention
Rest days are also instrumental in preventing injuries. Engaging in continuous physical activity without allowing your body time to recover can increase the risk of overuse injuries. These are often a result of cumulative strain on the muscles, tendons, joints, and bones, which can be mitigated by integrating rest days within your exercise schedule.
Athletes with less than 2 rest days per week during the training season had 5.2-fold risk (95% confidence intervals [CI] 1.89-14.06, P=0.001) for an overuse injury.

This downtime allows the muscle tissue that has been stressed during exercise to heal properly, reducing the risk of injury due to overtraining.
Prevention of burnout
Many athletes and fitness enthusiasts experience an emotional and physical plateau known as burnout. To prevent this, rest days must be part of their routine. Rest allows the mind and the body to disengage from the demands of intense exercise regimens, thereby maintaining motivation and enthusiasm for training.
Active recovery through light activities on rest days can additionally help in maintaining a routine without over-exerting. Scheduling days of rest helps to prevent feelings of fatigue and exhaustion, which can ultimately lead to a drop in performance and a loss of eagerness for the activities once enjoyed.
In conclusion, rest days vary from one individual to another, depending on fitness level, training intensity, and specific fitness goals. Generally, allowing a couple of days of rest per week can be an effective strategy to optimise workout results and maintain both physical and mental health. While professional athletes may require a different approach to rest and recovery time, for the average person, balancing active rest day and training days within the week is crucial for sustainable, long-term fitness success.
How many rest days do you need?
The answer to the question “How many rest days do you need?” is not one-size-fits-all. The ideal number of rest days depends on a variety of individual factors, including age, the intensity of workouts, and personal recovery capabilities.
It’s understood that after exceptionally intense exercise, a standard recovery period could range from 3 to 7 days to allow for complete rest, hydration, and adequate sleep. This ensures that energy stores are replenished and that micro-tears in muscle tissue can heal.
Active recovery, incorporating light activities such as walking, swimming, or light jogging, also plays a valuable role in facilitating muscle healing without imposing undue stress on the body. These lighter efforts can help boost circulation, carrying nutrients and oxygen to tired muscles, and aiding in the removal of metabolic waste products.
The training principles of cross training, alternating hard and easy training days, and rest days reduce the risk of an overtraining syndrome in rowers.

Nonetheless, rest days where minimal physical exertion takes place are critical to avoid overtraining, reducing the risk of injury, and enhancing muscle growth and overall athletic performance.
Factors to consider
When planning rest days, key factors to take into account include fitness level, age, and workout intensity, all of which influence how much recovery time your body needs. For instance, the rest days required after strength training typically range from 72 hours (3 days) up to an entire week. These days allow for the body to repair stress on joints and muscles, counteract fatigue, and help overcome training plateaus.
It’s crucial to remember that muscle mass is actually built outside the gym; the rest period is when muscle tissue repair and growth occur. Thus, rest is an integral stage in the muscle-building process. To build muscle effectively and safely, one must not only engage in a strength training programme that employs progressive overload but also focus on proper nutrition, quality sleep, and stress management.
Research indicates that, at minimum, two strength-training days per week are essential for muscle growth, highlighting the importance of customising the number of rest days to individual recovery needs between training sessions.
Expert recommendations
The best way to pinpoint the exact number of rest days suitable for you is to consult a qualified fitness professional who can tailor recommendations to your specific goals and situation. Importantly, it’s essential to tune into your own body and adjust rest periods accordingly, based on your levels of fatigue and progress in workouts.
Rest is not just a passive activity; it’s a key component in muscle repair, preventing fatigue, and improving overall performance. Whether you’re a novice to exercise or a seasoned athlete, regular rest is a must.
During rest periods, muscle fibres recover and rebuild, something that occurs when you’re not working out. Understanding that muscle growth takes place during downtime – especially through proper sleep and rotating muscle groups to ensure each has time to recover – is critical for anyone dedicated to bodybuilding or physical fitness.
In summary, it is essential to implement an individualised approach to rest days, allowing your body to recover optimally and support your fitness objectives.
Signs that you may need an extra rest day
Recognising when to incorporate an extra rest day into your training routine cannot be overstated, as it’s crucial for maintaining both physical and mental well-being. Here are some telltale signs indicative of the need for additional rest:
- Difficulty waking up, which may often be accompanied by irritability and low motivation.
- A noticeable decline in concentration abilities and a general sense of heightened stress.
- Challenges with nighttime rest, such as trouble falling asleep or staying asleep, can be a red flag.
- Minor injuries, like persistent niggles, could also signal that your body needs more time to recover.
- Heart rate variability (HRV) metrics may suggest under-recovery if your readings are abnormal compared to your baseline.
- General feelings of burnout or physical fatigue should alert you to the potential benefits of taking another day off.
Feeling stressed
Stress has a multifaceted relationship with exercise. While physical activity is renowned for reducing stress via endorphin production, excessive stress paired with overtraining can detrimentally affect the body. Too much stress can disrupt the balance of serotonin and cortisol, hormones responsible for mood regulation, potentially leading to mood swings and heightened irritability.
To combat stressful periods, integrating relaxation-focused or low-intensity workouts such as yoga or leisurely outdoor walks may provide relief. It is especially important during these times to honour feelings of excessive exertion.
If common stress management methods don’t seem to be effective, it may be a sign to take a step back and allow the body to enjoy a well-deserved rest day, helping to prevent the ramifications of overtraining.
Being sleep deprived
Inadequate sleep extends beyond mere exhaustion; it’s linked with wide-ranging health concerns including metabolic dysregulation and cardiovascular issues.
When the body lacks rest, it experiences disturbances in hormones that influence hunger – leptin and ghrelin – potentially leading to changes in appetite and eating patterns. Further, it can spike sympathetic nervous system activity, heightening stress responses and dampening recovery.
To maintain optimal functioning, health experts advise 7-9 hours of quality sleep per night, emphasising its role in recovery, energy sustenance, and mental clarity.
If achieving this rest proves difficult or daytime fatigue persists, these are signals that the body might benefit from extra recovery time to offset the negative effects of sleep deprivation.
Experiencing excessive soreness
After an intensive training session, it’s normal to feel muscle soreness known as Delayed Onset Muscle Soreness (DOMS), generally appearing 24-48 hours post-exercise. However, when soreness is extreme and lasts more than a couple of days, it suggests that the workout may have been too strenuous for your current fitness level. Such prolonged or acute soreness can hinder your performance, lead to a fitness plateau, or worse, result in an injury.
It’s important to differentiate between the typical ‘good’ soreness, indicating muscle adaptation, and debilitating soreness signalling the need for rest. If after a day of rest and active recovery, the soreness has not lessened, consider allowing your body an extra day to heal the microscopic tears in the muscle tissue and restore your energy stores completely.
What to do on rest days
Taking a rest day doesn’t always mean doing nothing at all. To maximise the benefits of your days off from intense training, it’s crucial to engage in light, restorative activities that promote recovery without overexerting your body.
Engage in low-impact workouts
Low-impact workouts are your allies on rest days. They include activities like walking, swimming, biking, dancing, and even kayak excursions. These exercises are gentle on your joints and foster a sense of well-being by keeping you active in a relaxed manner.
Adhering to low-intensity, low-impact workouts at least once a week, especially after a series of intense workout days, helps in preventing overtraining.
Beginners should especially heed the body’s need to recover, providing each muscle group a substantial break of 2-3 days post-training, while veteran fitness enthusiasts can often afford a shorter recovery window of just 1-2 days. Always pay attention to persistent muscle soreness – it’s one of the clearest indicators that your body might be craving a rest day.
Focus on flexibility and mobility exercises
Incorporating flexibility and mobility exercises into rest days is perfect for keeping the body limber and prepared. Opt for activities that are low-stress, such as gentle yoga flows, dynamic stretches, and casual, scenic hikes, to maintain mobility.
Active recovery, which entails engaging in such light activities on rest days, promotes blood circulation, nutrient delivery to the muscles, and waste disposal through lymph flow.
It’s essential to choose activities that don’t overly elevate your heart rate, letting you concentrate on improving flexibility and mobility crucial for overall health.
Prioritise a healthy diet and protein intake
Proper nutrition plays a pivotal role in the effectiveness of your rest days. Ensuring an adequate intake of protein is paramount to facilitate the repair of muscle tissue during these quieter periods.
Active individuals should aim for a protein consumption of about 1.2 to 2.0 grams per kilogramme of body weight, distributed evenly throughout the day. It’s also wise to intake complex carbohydrates to restore glycogen levels, with the amount adjusted according to your levels of physical activity.
Though you might not need as many calories as on more active days, it’s important to heed your hunger cues for guidance on food intake. A balanced diet rich in proteins, complex carbs, and appropriate for your caloric needs supports muscle recovery and helps you reap the full benefits of your training.
Give your body a break
Days of rest are non-negotiable elements of a successful fitness regimen. They’re not just about physical recuperation; they also reduce the risk of burnout and injuries by giving overworked muscle fibres a chance to repair and rebuild.
Muscles actually grow during these intermissions in training, not during the exertions themselves. Especially for those powering through moderate to high-intensity workouts, it’s recommended to take at least one full rest day per week. However, the exact number may vary based on individual activity levels and the intensity of recent workouts. Listen to your body, and if it tells you to rest, obey – it’s through rest that strength is built and performance levels are elevated.
Remember, a holistic approach to fitness encompasses rest and recovery just as much as it does activity and exertion.
Balancing your training routine with ample rest days and engaging in the right activities during those days are crucial steps towards achieving your fitness goals while maintaining your body’s well-being.
