What is recovery?

When we think about improving our health, we often focus on being more active. While movement is important, recovery is too. Recovery is the time your body and mind use to rest, repair, and build after activity.

This does not mean doing nothing all day. Recovery is about giving your body the chance to recover from the effort you have put in. Taking regular rest days can help you feel stronger, reduce tiredness, and make it easier to stay consistent with your routine.
‍

Why are rest days important?

Exercise places your body under an amount of stress. During recovery, your body repairs muscles, replaces energy stores, and adapts so it is better prepared for the next session. This is one of the reasons why recovery is an important part of making progress.

Without enough rest, you may notice:

  • Feeling more tired than usual
  • Sore muscles that take longer to recover
  • Reduced performance during exercise
  • A greater chance of picking up an injury

Taking a planned rest day does not mean you are not progressing. In fact, it can help you return feeling refreshed, motivated and ready to continue.
‍

Different types of recovery

Recovery does not always mean sitting completely still. There are different ways to help your body and mind recover.

Complete rest: This means taking a break from planned exercise. This can be useful after a particularly challenging workout or when your body feels tired.

Active recovery: This involves gentle movement that does not place too much stress on the body such as: gentle stretching, yoga, mobility exercises or light gardening tasks.

Other parts of recovery are just as important. Good quality sleep, eating regular balanced meals, drinking 6 to 8 cups or glasses of fluid a day  and managing stress all help your body recover - supporting your overall health.
‍

How often should you take a rest day?

Everyone is different, so there is no perfect number of rest days. Your age, fitness level, health conditions and the type of activity you do can change the amount of rest you need.

A good approach is to listen to your body. If you feel unusually tired, sore, or find exercise feels much harder than normal, it may be a sign that you need more recovery. Common methods include having a rest day after an intense exercise session or at least 1-2 per week.
‍

Making the most of your recovery

Recovery is an active part of looking after your health. On your rest days, try to:

  • Get enough sleep
  • Stay hydrated
  • Eat balanced meals with enough protein
  • Keep gently active if it feels comfortable
  • Give yourself permission to rest without feeling guilty
    ‍

Summary

Recovery is an important part of progress. By giving your body time to recover, you will reduce your risk of injury and make it easier to stay consistent with your activity over time. Looking after your body on rest days is just as important as the exercise you do on active days.
