Interesting facts about exercise and health
The National Center for Health Statistics has found that a quarter of all Americans get virtually no exercise at all, putting them at higher risk of having a heart attack, diabetes and cancer.Levels of education, income and marital status seem to affect whether or not someone exercises. 1 in 4 adults with an advanced degree do high levels of exercise compared with only 1 in 7 with less than a school diploma. Men are more likely to exercise than women. People from the Southern States of America do the least exercise. The poorer you are the less exercise you do. Adults with incomes below the poverty level are 3 times less likely to exercise than adults in the highest income group.
Research undertaken at the University of Colorado has found that obese people have more trouble dissolving blood clots. A clot-busting agent called 'tissue plasminogen activator' is produced and released less in obese people who are inactive, leading to a greater likelihood of heart attacks or strokes. The study found that around half the obese participants who walked 40 to 45 minutes 5 times a week for 3 months began releasing the chemical t-PA needed to lessen their chances of getting a blood clot.

You've made the decision to do more exercise, so what's next?
Consult an expert? It may be a good idea to consult a qualified expert if:
Exercise and your heart
Get a heart workout. Your heart is most important muscle in your body and you must keep it in shape. It is this organ that you start with to build up your levels of stamina and strength. One of the most effective ways to do that is do regular aerobic exercise. That is exercise that works the large muscle groups. Cycling, swimming, stepping, brisk walking are the easiest and cheapest.
Use your pulse as a monitor to maximize the effect of your workout with the minimum input. Using a wrist monitor that displays your pulse rate makes this easier. Calculate your cardiac training range (CTR) by Firstly getting your maximum cardiac rate (MTR), something that you should not exceed during any form of exercise. To do this subtract your age from 220. Your Cardiac training range is between 70 and 85 per cent of your maximum training range. For example, if you are 40 years of age the MTR is 180 (220 minus 40)- your CTR is 126 to 153 (70 to 85 per cent of 180.
Knowing this you can adjust your workouts to get the most from the time you spend exercising. It is this area that you may need to adjust if you have a medical complaint and you should ask your doctor what range you should be aiming for.
Upping your metabolic rate
If weight loss is a major part of your exercise programme then your aim is to maximize the calories you burn up. This will depend on the amount of effort you put in. Examples are, brisk walking burns up 200 to 250 calories an hour, jogging-about 400-600, cycling 200-650.
