Weight loss is acheived increasing the calories burned in relation to calories consumed. But after your doctor suggest it, how much and how hard should you exercise? There is any easy way to determine appropriate exercise intensity regardless of your age or physical condition.
To determine your maximum heart rate, subtract your age from 220. I am 37, so my maximum heart rate is 183.
Exercise should NOT be done at your maximum heart rate, but at 70 to 85% of it. So, my optimum exercise level is at 128 to 155 beats per minute.
To encourage good health, this intensity of exercise should be performed for 20 or 30 minutes 3 to 5 days per week. For weight loss, exercise at your target heart rate for 30 to 60 minutes, 5 days a week.
Remember to get your physicians approval prior to starting an aggressive exercise program.
