Physical fitness is very important in today’s world. Everyone is enjoying the benefits of greater strength and feeling better. Exercise keeps your body strong and healthy.

How does exercise benefit me?

In addition to increased energy, other benefits from exercise may include:

  • improved muscle physical functioning
  • better blood pressure control
  • improved muscle strength
  • lowered levels of blood fats (cholesterol and triglycerides)
  • better sleep
  • better control of body weight

Do I need to see my doctor before starting exercise?

Yes. Before beginning any exercise programme be sure to check with you doctor.

step aerobics>When planning a directed exercise programme, you need to look at four things:

  • type of exercise
  • length of time you spend exercising
  • how often you exercise
  • how hard you work while exercising.

Here are some tips on each:

Type of Exercise

Choose continuous activity such as walking, swimming, bicycling (indoors or out), skiing, aerobic dancing or any other activities in which you need to move large muscle groups continuously.

Low-level strengthening exercises may also be beneficial as part of your programme. Design your programme to use low weights and high repetitions, and avoid heavy lifting.

How Long to Exercise

Work toward 30 minutes a session. You should build up gradually to this level.

How Often to Exercise

Exercise at least three days a week. These should be non-consecutive days, for example, Monday, Wednesday and Friday. Three days a week is the minimum requirement to achieve the benefits of your exercise.

How Hard to Work While Exercising

  • Your breathing should not be so hard that you cannot talk with someone exercising with you. (Try to get an exercise partner such as a family member or a friend.)
  • You should feel completely normal within one hour after exercising. (If not, slow down next time.)
  • You should not feel so much muscle soreness that it keeps you from exercising the next session.
  • The intensity should be a “comfortable push” level.
  • Start out slowly each session to warm up, then pick up your pace, then slow down again when you are about to finish.

The most important thing is to start slowly and progress gradually, allowing your body to adapt to the increased levels of activity.
