CV-Cardio-Vascular

CV-Cardio-vascular (involving the heart and lungs)

Aerobic fitness is defined as the body's ability to take up, transport and utilise oxygen.

Aerobics and cardio exercise (running, cycling, swimming type activities) are all about looking after your heart and lungs, as well as improving your energy levels and stamina. Your heart is working all day every day circulating blood and nutrients to your body.

By your 60 th birthday your heart will have beat an incredible 2.2 billion times!

Your heart is a muscle (a very special one) and like all muscles it responds and adapts to overload and stimuli growing stronger and healthier(or smaller and weaker, if neglected!).

Many people believe that exercise has to be hard and gruelling to be effective, but moderate exercise for 20 minutes 3 times a week will give you excellent health related fitness and give your heart a long and healthy life.
