Fitness: Exercise for a Healthy Heart (cont.)

How Often Should I Exercise For A Healthy Heart?

In general, to achieve maximum benefits, you should gradually work up to an aerobic session lasting 20 to 30 minutes, at least three to four times a week. Exercising every other day will help you keep a regular aerobic exercise schedule.

What Should I Include in My Program?

Every exercise session should include a warm-up, conditioning phase and a cool-down.

  • Warm-up. This helps your body adjust slowly from rest to exercise. A warm-up reduces the stress on your heart and muscles, slowly increases your breathing, circulation (heart rate) and body temperature. It also helps improve flexibility and reduce muscle soreness. The best warm-up includes stretching, range of motion activities and the beginning of the activity at a low intensity level.
  • Conditioning. This follows the warm-up. During the conditioning phase, the benefits of exercise are gained and calories are burned. Be sure to monitor the intensity of the activity (check your heart rate). Don't over do it.
  • Cool-down. This is the last phase of your exercise session. It allows your body to gradually recover from the conditioning phase. Your heart rate and blood pressure will return to near resting values. Cool-down does not mean to sit down! In fact, do not sit, stand still or lie down right after exercise. This may cause you to feel dizzy or lightheaded or have heart palpitations (fluttering in your chest). The best cool-down is to slowly decrease the intensity of your activity. You may also do some of the same stretching activities you did in the warm-up phase.

What Is the Rated Perceived Exertion Scale?

The Rated Perceived Exertion (RPE) scale is used to measure the intensity of your exercise. The RPE scale runs from 0-10. The numbers below relate to phrases used to rate how easy or difficult you find an activity. For example, 0 (nothing at all) would be how you feel when sitting in a chair; 10 (very, very heavy) would be how you feel at the end of an exercise stress test or after a very difficult activity.

Rated Perceived Exertion (RPE) scale

0

Nothing at all

0.5

Just noticeable

1

Very light

2

Light

3

Moderate

4

Somewhat heavy

5-6

Heavy

7-9

Very heavy

10

Very, very heavy

In most cases, you should exercise at a level that feels 3 (moderate) to 4 (somewhat heavy). When using this rating scale, remember to include feelings of shortness of breath, as well as how tired you feel in your legs and overall.
