A safe and progressive exercise programme will encourage you to take small and achievable steps towards better fitness, no matter what level you're starting from.

Rosemary and Mary have both had almost 50 years' experience in helping people to lose weight and get fit and have now condensed their joint expertise into this simple and accessible plan with advice to boost your body's natural defences so you can become fighting fit from home in less than a month.
