Why is this study important?
People need to do exercise to stay healthy and all the research shows that being active, even if it is just a little bit active, is better than doing nothing at all. Exercise not only helps you stay fit but it helps you keep your weight down, improves the health of your heart and lungs and is even thought to help alleviate depression and delay the onset of dementia in older people. Currently GPs can refer people for exercise as a kind of treatment and this trial is trying to work out what kinds of exercise programme are most effective in helping people adopt and maintain an active lifestyle.
