Body Analysis

Body Analysis

Whatever training goals you agree with John, body analysis gives you vital knowledge of your current situation.

Whenever we set goals for ourselves, we always need to make sure they are measurable. However, without an accurate assessment of things as they stand, this becomes impossible. Furthermore, any assessment methods used need to be validated measuring protocols which produce accurate results.

We can then compare these results against normative data tables (e.g. a BMI chart) produced by employing the same protocols. This also means that each test is reproducible and, therefore, generates reliable results every time. This is very important for measuring your progress through re-assessment.


Most of us weigh ourselves regularly, as we are interested in our health and fitness and know that weight has an important influence. However, the scales tell only part of the story. Much more useful information can be obtained by periodically checking both percentage body fat and weight. This allows us to monitor changes to muscle and assess progress as we lose body fat and make adjustments to our lifestyle.

For an explanation of why Body Fat Measurement combined with weight is so significant, please read The Importance of Body Fat Measurements.

Waist-to-Hip Ratio

The waist-to-hip ratio is one of the most used clinical applications of girth measurements. This assessment is important because there is a correlation between chronic diseases and fat stored in the midsection of the body.

Blood Pressure

Blood pressure can be explained as the force exerted by blood against the blood vessel walls. Health professionals often use blood pressure to indicate the general state of the circulatory system. It should always, therefore, be an integral measure in assessment prior to engaging in a programme of exercise.

John can give you useful information regarding a benchmark range for blood pressure, so you can assess your blood pressure reading result. You can then use this to create another measurable goal (to maintain or reduce the reading, for example).

As a fitness professional, John won’t offer medical opinions regarding blood pressure. However, John will advise you to contact your GP if readings fall outside of the normal or safe range according to exercise guidelines.


One way to measure body fat and assess obesity in adults is by use of the body mass index (BMI). Although not designed to assess body fat, the body mass index (BMI) is a quick and easy method for determining if a person’s weight is appropriate for his or her height. Medical and health professionals use BMI extensively as a means of determining the risk of health complications associated with excess body fat, especially with scores above 40 (morbid obesity).

Individuals are considered to be at especially high risk for health problems if they fall into the BMI range of 25 to 34.9, and have a waist size of

  • over 40 inches for men
  • over 35 inches for women

Specifically, they have a greater risk of developing Type 2 Diabetes, Hypertension and Cardiovascular Disease. Consequently, we also take waist circumference into consideration.

An athlete who has a large percentage of lean body mass will tend to give a high reading (obese) due to the fact that BMI does not take body composition ratios into consideration. Because muscle weighs more than fat, we do not use  the absolute reading of body weight in this index as the sole means of measuring healthy weight.

Tanita Body Composition and Segmental Analysis

Much more than a weighing scale, Tanita devices use advanced Bio-electrical Impedance Analysis (BIA). The base and hand-held electrodes send a very low, safe electrical signal through your lower and upper body, and abdomen.

This electrical signal measures the resistance and reactance of different tissues within the body. The Tanita device then calculates your body composition measurements by inputting this data scientifically validated equations. Separate segmental analysis (both arms, both legs, trunk) is provided, including:

  • Body Fat Mass
  • Muscle Mass
  • Visceral Fat Rating
  • Basal Metabolic Rate (BMR) Score
  • Metabolic Age
  • Total Body Water Percentage
