The Power of Knowing: BBT's InBody Assessment and the Benefits of Tracking Your Body Composition

By: Nazirah M. Jones M.S., CPT-NASM

Tracking your progress is key to achieving success on your fitness journey. At BBT Fitness, we take progress tracking seriously, which is why we offer our members the InBody Body Composition Scanner on a monthly basis during BBT Success Week. This powerful tool provides detailed measurements of your weight, lean body mass, body fat percentage, and body fat mass, giving you an accurate snapshot of your progress and helping you make informed decisions about your fitness goals.

How to Read Your Results

Body Fat Mass

The total amount of body fat you have, in pounds. Excess body fat can increase your risk for certain disease progression and limit your functionality while too little body fat can also have negative outcomes as well.

Skeletal Muscle Mass

We will use this as our measurement for muscle. Typically you will want to see this number stay the same or increase.

Total Weight

This is your total body weight as you would see it on a scale.

PBF (Percent Body Fat)

This is a category of health. It can be used similarly to BMI. It is influenced by your muscle and body fat mass.

Body Composition History

If you are logging in with your username each time, you will see a history of your body composition that will always show your last eight scans, so you can track how your progress peaks and valleys.

Frequently Asked Questions:

Q: How does the scan work?

A: InBody devices use a method called Bioelectrical Impedance Analysis (BIA) to measure body composition, which divides your weight into different components, such as Lean Body Mass and Fat Mass, to assess health and help guide interventions.

However, unlike other body composition analyzers, we do not use empirical estimations such as age, gender, ethnicity, athleticism, or body shape.

Q: How accurate is the scan?

A: InBody ‘s four pillars of technology to provide clients with accurate and precise direct segmental measurement multi-frequency bioelectrical impedance analysis (DSM-MFBIA) results that have been extensively validated to gold-standard methods.

Keep in mind that as a scanning machine, it will not be as accurate as a hydrostatic test, but it will give you a very accurate baseline and repeat analysis. Keeping the conditions of your scans the same, you’ll be able to track measurable and meaningful progress.

Q: What are “good numbers?”

A: While it can be relative to your body type since we are all genetically predisposed to various weight tendencies, here are some very general established health parameters:


  • Under 10% –> Very Lean

  • 10% – 15% –> Lean, Great Shape!

  • 15 – 20% –> Above Average, Good Shape!

  • 20 – 25% –> Average

  • 25 – 29% –> Slightly Overweight, a Little Out of Shape

  • 30%+ –> Overweight, Out of Shape


  • Under 15% –> Very Lean

  • 35% –> Overweight, Out of Shape

Q: Should I care about my BMI?

A: In this context, we will not be putting significance into your BMI reading. Your body fat percentage is the most relevant number.

Q: What is a reasonable goal?

A: Losing 2-5 pounds of fat per month or gaining 2-5 pounds of muscle per month are both reasonable expectations with a proper, sustainable diet and frequent outcomes.

Q: When should I conduct my InBody Assessment?

A: All InBody Assessments are done during the first week of each month during BBT Success Week. For the best results, complete the assessment prior to training.
