Overtraining and rest

Exercise is good for us, but more is not always better. Pushing your body without enough recovery can quietly work against your wellbeing.

What it is

Overtraining happens when the amount or intensity of exercise consistently outpaces the body's ability to recover. Rest is not the opposite of progress - it is the part of the process where muscles repair, energy stores rebuild and the nervous system settles. Without enough recovery, people can experience persistent fatigue, mood changes, disrupted sleep and a higher risk of injury or illness. This is especially common among people using exercise to manage stress, who can end up adding another source of pressure instead of relief.

Signs to notice

• Ongoing tiredness that does not improve with a normal night's sleep
• Declining performance despite training harder
• Irritability, low mood or anxiety linked to missed workouts
• Frequent minor injuries, illness or a lingering sense of being run down
• Resting heart rate that stays elevated, or trouble sleeping despite exhaustion
• Feeling guilty or anxious about taking a rest day

What helps

• Build rest days into your training plan deliberately, rather than only resting when forced to by injury or illness.
• Vary intensity across the week - not every session needs to be a maximum effort.
• Prioritise sleep, as this is when most physical recovery happens.
• Fuel your body adequately for the amount of activity you are doing.
• Notice the difference between healthy discipline and using exercise to punish or control yourself - these come from very different places.
• Talk to someone if you find it hard to rest without guilt - this often points to something worth exploring beyond fitness.
• Track how you feel, not only performance numbers, to get a fuller picture of your recovery.

When to reach out for help

See a doctor if fatigue, low mood or physical symptoms persist despite adequate rest, as this can sometimes point to another underlying issue. Speak to a mental health professional if exercise has become driven by guilt, anxiety or a need for control rather than enjoyment and health, or if rest days bring on significant distress.
