Along with jogging and swimming, cycling is one of the best all-round forms of exercise.

It can help to increase your strength and energy, giving you more efficient muscles and

stronger heart. But increasing your strength is not the only advantage of cycling. Because

you’re not carrying the weight of your body on your feet, it’s a good form of exercise for

people with painful feet or backs. However, with all forms of exercise it’s important to

start slowly and build up gently. Doing too much too quickly can damage muscles that

aren’t used to working. If you have any doubts about taking up cycling for health reasons,

talk to your doctor and ask his/ her advice.

Ideally you should be cycling at least two or three times a week. For the exercise to be

doing you good, you should get a little out of breath. Don’t worry that if you begin to

lose your breath, it could be dangerous and there must be something wrong with your

heart. This is simply not true; shortness of breath shows that the exercise is having the

right effect. However, if you find you are in pain then you should stop and take a rest.
