Taking regular exercise has many benefits for your health including your cholesterol levels.  Engaging in regular physical activity will help to lower your LDL and at the same time to increase your HDL.  On the other hand lack of physical activity is a major risk factor for heart disease and so it is important to incorporate some form of exercise into your daily routine.

Regular physical activity is good for you in many ways in addition
to helping you raise HDL and lower LDL. Exercise is good for your heart and lungs, and it can also help lower your blood pressure. Regular exercise will burn calories and so help you control your weight. There are mental benefits too. You'll feel more confident and find that exercising is a great way of relieving stress and beating the blues. 

Becoming physically active does not mean that you have to spend hours in the gym or complete a ten mile run every day. In fact, if you have not been taking regular exercise, you should start slowly and then gradually increase the time and intensity. Anyone who has a heart condition or is over age 40 should consult their doctor before taking up any strenuous exercise program.

If you are currently physically inactive start slowly. For instance, begin by taking a walk during your lunch hour. Then gradually walk further or increase the pace. A brisk walk for 30 minutes twice a week is generally regarded as sufficient, but if you can manage to do this every day, this is the ideal.

Brisk walking is regarded as a moderate-intensity activity, as are playing golf, cycling, dancing, bowling and gardening. More intense forms of exercise include jogging, swimming or playing football, basketball or tennis. As you would expect, the more intense the activity, the more calories you will burn. For example, 30 minutes of brisk walking will burn 170 calories, whereas the same time spent jogging at 5 miles per hour will burn 275 calories.

So the message is that exercise is good for you, good for your heart and good for your cholesterol levels. Start slow, keep it up every day and you will find that you are feeling better, have more energy, more confidence and that you are having fun!
