Planning to join a gym? Here’s what to expect from a fitness test.

Getting in shape is a common goal for the New Year. Before you start an exercise or weight loss program you may want to have a fitness test to determine your current status and to assess improvement as you progress through the program. If you join a gym, a fitness assessment may be required. This is smart, since a fitness test is important for determining a safe and effective exercise recommendation. This is the topic of my Health & Fitness column in the Aiken Standard this week.


A good fitness test should include measurements of muscular strength, aerobic fitness, flexibility, and body composition. While the specific test procedures may vary, here is a description of what you might expect during your fitness test.

Muscular strength is measured using a one-repetition max (1-RM) test in which the heaviest weight you can lift is determined, typically for the bench press and the leg press. Sometimes alternative tests are used, such as the number of push-ups or sit-ups you can do. Handgrip strength can also be used as a rough estimate of overall muscular strength.

Cardiorespiratory or aerobic fitness is the ability of your heart and lungs to supply oxygen to your exercising muscles. The “gold standard” is to actually measure the amount of oxygen you breathe during vigorous exercise, called maximal oxygen uptake or VO2 max. This test requires specialized equipment that is typically only available in exercise labs, so most fitness tests estimate VO2 max.

Your aerobic fitness test will probably be a submaximal test in which your heart rate is measured as you exercise at several intensities on a treadmill or stationary cycle. The change in your heart rate is used to estimate your VO2 max.

Flexibility is an important, but often overlooked, component of fitness. Flexibility is usually measured using the sit-and-reach test which assesses low back and hamstring flexibility.

Body composition refers to your percent fat, which is of interest to people who want to lose weight or build muscle. The most common method of measuring percent fat is skinfolds, in which the thickness of your skin and subcutaneous fat is measured at several sites on your body. The most important criteria for accuracy of skinfolds is the skill of the tester, so look for someone who has years of experience to measure your skinfolds. There are more accurate methods of measuring percent fat but they are limited to research and clinical purposes.

Simpler methods of assessing your body weight and fatness include body mass index and circumferences. Body mass index can be calculated from your height and weight (look online for a BMI calculator) and is widely used to assess body weight and health. Waist and hip circumferences are determined using a measuring tape and provide more information about where fat is stored. Upper body fat (high waist circumference) is associated with higher health risk than lower body fat (low waist measurement).

There are two additional points to remember before you have a fitness test or start an exercise program. First, you should see your doctor if you are new to exercise or have had changes in your health. Second, a fitness test should be conducted by a qualified professional. Make sure the personal trainer or fitness professional you work with is certified and has experience with fitness testing.

Finally, and most importantly, use the results of your fitness test to motivate you so you can see improvements as you get more fit in 2016!


Nutrition, exercise, and health information can be confusing. 
But it doesn't have to be that way.
