Publisher's Synopsis
This book will assist you to improve your aerobic finess levels, and improve your overall health. You will also learn about the body, its functions and how to assist others in obtaining their aerobic fitness goals. To remain aerobically fit, you need to regularly do something which will increase your heart rate above its normal level. This could be exercise but it could also be work: in fact it can be any physical activity which causes the heart to beat faster than normal. For this activity to be effective the heart rate must be sustained for at least 20 minutes in each session, and there must be at least three such sessions per week.
