This is the first step to managing your performance and health over time. Large increases in work over a short period of time, or constant high amounts of work without adequate recovery may put you at risk for breakdown or injury. For example, if the highest amount of work you have sustained during a session is 100 kJ (kilojoules), and the workout for today is 200 kilojoules, this may be beyond your current capabilities. The same principle can be used week over week or month over month. The accumulation of work over longer periods (weeks and months) should be slow and consistent. Conversely, large drops in work over time can lead to de-training. Strategic low work periods (days/weeks) can aid in recovery and increase performance over time.
