Exercise is an essential component of healthy living. It not only increases the level of HDL (“good”) cholesterol in the blood, but also reduces the level of LDL (“bad”) cholesterol. In addition, it helps us to maintain our weight within a healthy range, lower our blood sugar levels, and improve our overall cardiovascular fitness. A physically active person is approximately 1.5 times less likely to develop heart disease and 30-50% less likely to be hypertensive. Conversely, lack of exercise may leave a person more vulnerable to developing diabetes, high blood pressure, and obesity. Fortunately, exercise need not be overly strenuous before we are able to derive health benefits from it. Just 30 minutes of physical activity (for instance, brisk walking, aerobic dancing, swimming) at least five times a week can substantially reduce your risk of cardiovascular disease and diabetes.
A proper exercise programme should include a:
The warming-up phase typically consists of 5 to 10 minutes of gentle stretching and calisthenics to warm up the muscles and reduce the risk of injury during exercise. The conditioning phase, which should form the main component of your exercise sessions, involves aerobic and/or strengthening exercises. Aerobic exercises (for instance, cycling, jogging, swimming) help to improve your blood circulation, while strengthening exercises such as lifting weights help to build and tone your muscles. Following the conditioning phase is a cooling-down period of 5 to 10 minutes to round off the exercise session.
If exercise is not currently a regular part of your life, here are some simple tips to help you incorporate it into your routine:
Go to the gym or do light exercises as much as you can everyday, e.g. use stairs instead of escalator or lift, and walk to your colleague instead of emailing or making a phone call. You will soon notice that it is not difficult to exercise at least 30 minutes a day. Aim to make this a daily routine or at least 5 times a week. You may estimate your target exercise heart rate as follows:
Exercise Heart Rate = (170 – age) beats per minute
This formula can be used as a guide for beginners. People involved in regular physical activity are recommended to calculate target heart rate following the standard formula provided here.
In Singapore, easy and affordable access to exercise facilities is available to all. The Singapore Sports Council operates an island-wide chain of ClubFITT gymnasiums, while the People’s Association provides a wide range of sports facilities at its Sea Sports Clubs and Community Clubs/Centres.
