You may be tempted, as many of us are, to ‘work through the pain’ to get jobs done that need to be done. The result is usually more pain later that day or for many days after. Unfortunately, this pattern (known as boom / bust) is not helpful for the body as we need consistent exercise to maintain our health and fitness.
Pacing is all about learning how to break tasks into smaller more manageable components and taking frequent breaks. If you have many tasks that must be completed through the day, have a think about their physical toll on your body. Try to pace them throughout the day rather than do them all in the morning for example.
