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 a 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 for 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.
