The recommended intensity

Exercise intensity can be calculated in a number of different ways. In a lab it can be measured through gas analysis, examining how much oxygen the exerciser is taking into the body and transporting to the working muscles. In the fitness center it can be measured using a heart rate monitor, which reports the heart rate at diverse workloads.

It's a speed at which you feel you're making good progress whilst still being able to hold a chat.

Duration of the work out

Right at the beginning at school we have to learn to 'sit still' - and we consider it not unusual to spend hours sitting or lying in front of our TV.
