How Do You Know if You’re Fit?

We tend to think that a fit person is someone who looks good, eats healthy food, and is slim and active. However, this assessment is superficial at best and it gives little indication of a person’s capacity to endure physical activity.

Did you know that there is a simple way you can measure your own fitness? Measuring fitness, or cardiovascular capacity, is a complex and expensive procedure done in a doctor’s office. However, nowadays there is a simple way you can measure your own fitness level in one of many exercise machines available at gyms or in your own living room.

Your exercise machine at home or at your gym can help. Most of today’s exercise machines such as treadmills, elliptical trainers, or rowing machines are equipped with a metabolic equivalent (MET) level display. One MET is the amount of oxygen used when you are completely inactive, such as when you are at rest (one MET is equivalent to 3.5 ml of oxygen per kilogram of body weight per minute). The American College of Sports Medicine states that non-athletic, middle-aged men and women of average health have peak exercise capacities in the range of 8 to 10 METs, while an athlete can have values as high as 18 to 24 METs.

Assess your current physical condition, set your own goals and manage your own fitness. By getting on an exercise machine that displays METs, you can gauge your cardiovascular fitness and determine a starting point from which to make improvements. Current guidelines from the Centers for Disease Control and the American College of Sports Medicine recommend exercising at 3 to 6 METs, or 3 to 6 times the resting metabolic rate.

Here are some helpful tips to help you utilize this information toward fitness improvements:
Exercise at 3 METs at the beginning of an exercise program. Remember that it takes about 90 days to develop a habit, so practice is needed!
Any activity that burns 3 to 6 METs is considered moderate-intensity physical activity.
To get the health benefits or exercise, The Centers for Disease Control and Prevention recommend that you exercise at an intensity of at least 3 to 6 METs during every workout. Any activity that burns more than 6 METs is considered vigorous-intensity physical activity.
Thirty minutes of uninterrupted exercise at moderate intensity at least three times a week will get you on your way to achieving your target MET. According to the Journal on Active Aging, July-August 2002, every MET increase in a person’s exercise contributes to a 12 percent reduction in mortality.
Try boosting your fitness by reaching your target Try boosting your fitness by reaching your target MET level for short periods during your workout. The MET reader in your exercise machine will display your effort in numbers, but always pay attention to how you feel.
Exercise researchers have developed a simple calculation to help you determine your target MET level:
• For women:
MET level = 14.7 – (0.13 x your age in years)
• For men:
MET level = 14.7 – (0.11 x your age in years)

Determine the intensity levels of various physical activities using the table included. Remember to consult with your doctor before starting any exercise program.
