Exercise is vital for people in pain, as the saying goes, use it or lose it. However you need to be sensible about exercise or if you are not careful might end up like the person on the stretcher. Warm up before, after any exercise and gradually build up to your peak fitness
The following is an extract from the HDA's Report
The Health Development Agency (HDA - formerly the Health Education Authority) has recently evaluated its Active for Life programme, which encouraged sedentary people to increase their physical activity levels. It found that, despite wider recognition of the need for regular exercise, there was no change in the number of women meeting recommended activity levels and a slight decrease for men.

According to the HDA you should aim for at least 30 minutes of moderate-intensity activity five days a week. This should leave you warm and slightly out of breath and could take the form of a brisk walk, cycling or housework. If you're already active and want to do more, you should aim for at least 20 minutes of vigorous activity, for instance, running, squash or aerobics, at least three days a week. This should leave you sweaty and out of breath.
