Step on the scale in bare feet. Stretch both arms and spread them 30° from the body.
Do not speak or move the body until the measurement is completed.
Do not bend or shake the arms until the measurement is completed.
The measurement will be stopped if all eight electrodes are not fairly touched.



How to touch electrodes
Make sure that the plate electrodes are clean. Use antiseptic wipes on all silver plate electrodes after each use to ensure cleanliness and hygiene.
Ensure you wipe your hands and feet prior to measurement, removing any sweat or foreign matters from the soles. This will ensure an accurate reading, and provide a hygienic environment.
Take off your socks or stockings, then stand evenly on the plate electrodes with full heel contact.
When ankle electrode is selected to measure body composition, pull down the socks as shown in the picture.

How to grip handle electrodes
Ensure contact with all fingers including thumbs and palms as shown in the image.
Ensure palms have full contact with electrodes at all times.
Stretch out arms enough to ensure that arms are not touching the body.
Stand still throughout the measurement ensuring there is not movement of the head, arms or feet.



As with all forms of body composition, the technology of bioelectrical impedance (BIA) requires standardized conditions when scanning to provide proper repeatability of measurements. The technology reads impedance and reactance of tissue at a point in time which can differentiate Lean Body Mass from Body Fat Mass.

The human body is quite dynamic in response to training stimulus, nutrient partitioning and supplementation/medications so those things need to be taken into account with respect to scan readings. The technology is validated in science and used in medicine so generally, variabilities in scan results are mostly due to human factors, this is why we always ensure there are standardized conditions around testing.

The most important aspect of using BIA technology is to ensure the circumstances around comparison scans are controlled, so all scans need to be performed under the same conditions each time.

Crunch Fitness



The key components on your scan results to check are your weight, lean body mass, body fat mass, skeletal muscle mass and total body water.

Whilst people always look at body fat percentage as a show of progression, the reality is that it is only a percentage of your total body weight and not always a reflection of how much body fat has changed. The best way to track body fat is to track Body Fat Mass in kilograms or pounds.

The largest margin of error can be seen by checking Total Body Water. Being a component of Lean Body Mass, this is where you can identify whether the scan result has been affected by a human factor that is influenced by something that has altered Total Body Water. This is why it is imperative to control the scanning conditions as much as possible.

This is also where it is most important to note anything that can have an effect on Total Body Water such as:

Inflammation from training load
Hormonal changes
Severe temperature changes
Medications prescribed i.e. blood pressure medication or non-prescribed ie marijuana, CBD
Supplements such as cell volumizing products i.e. creatine, beta alanine, pre workouts etc.
Dehydration (it is common for people to not want to drink water before a “weigh in”)
Evolt 360 Body Composition Scanner Report



Physiologically speaking there are a number of human variables that can attribute to a scan result not reflecting an expected result or change and this is why there is a significant emphasis on controlling scan conditions.

For initial scans, areas to check are:

Have you consumed any caffeine?
Have you recently trained or have a raised temperature?
Ensure you had full contact of the silver tactile points on the machine throughout the scan process (especially palms)
Have you taken any cell volumizing supplements or medications that alter hydration?
Ensure your height is correct

If you are female, where are you in your menstrual cycle? If you don’t know, always scan the same time of day in 4 weeks or 8 weeks.

Some people will have an expectation of their Body Fat Percentage which might not reflect on the scan result. The BIA device can only provide a result based on the impedance and reactance of tissue, and therefore the result is reflecting the state of the body at the time of scanning. The first scan result is only a baseline and the emphasis should be on the follow up scan results, not the initial scan. Furthermore, where body fat is concerned, the total Body Fat Mass (kg or lbs) is where the emphasis should lie rather than Body Fat Percentage.


From a hormonal perspective, there are significant fluid shifts within the menstrual cycle as you can see from the diagram depicting the controlling hormone changes. You can see where the hormones rise, this is where you will see significant fluid shifts. The first 5-7 days are the best days to scan, where the hormone levels are fairly stable. The levels of hormones estrogen and progesterone fluctuate throughout the cycle and can lead to water retention. Water retention is highest around the midpoint of the monthly cycle and the 1-2 weeks before a period.

It is important to note that this is a guide only and you will come across the odd client that typically holds fluid in different circumstances, but for the most part, use this is a general guide.

Similarly, women in peri, post or menopause can experience fluid shifts due to drops in estrogen and progesterone. The take home message is to scan at the same time of the day within 4 or 8 weeks from each other to try and keep standardized scanning conditions.

Body Scan Results



Significant training loads can produce inflammation and fluid retention. Sometimes you may experience a scan result where the results may not be reflecting your expectation.

It is not uncommon for some people to experience plateaus and sometimes increases during a fat loss phase. It is never a linear process and the human body is subject to a number of different processes to recover, replenish and normalise certain functions. In most cases, if the client is being compliant, they should re-scan again at another interval (under the same scanning conditions) to reassess. It is always important to encourage the client to stay on track and discuss the various factors that could potentially show a result that didn’t meet expectations.

From a nutrition perspective, reducing carbohydrate consumption will initially provide a substantial change as 1 gram of carbohydrate bonds with approximately 3 grams of water, so this is why there is often a decent change from the first to second scan result in a fat loss phase.

Carbohydrates are also required to replenish glycogen stores in the muscle (as well as the liver). Excess carbohydrates or a high carbohydrate meal can momentarily clause fluid shifts and alter a scan result, so keeping food choices similar in nature around scanning, is important.

Finally, remember that using the Evolt 360 scan gives you some important data about your body. It is a collection of data around your own individual circumstances. It gives you an opportunity to learn what variables effect your body composition.

Managing  expectations around scan results is key to keeping motivated. The scan is only one piece of information from the state of the body at the time of scanning. Other key indicators such as increased energy, increased strength, feeling and looking better in clothing, feeling confident etc. are all important factors.

Body Scan Results


Challenges are a great way to start your fitness journey. Done properly, not only do they allow you to establish a clear, time driven goal but they offer the necessary support, information and motivation to get you there.


Many facilities don’t offer their clients a way to effectively measuring their progress to ensure they are on track to reach their goals. From a recent survey conducted, over 68% of gyms, health businesses, and personal trainers did not know how effective their member’s training was or what they needed to do to keep their members on track.

The Evolt 360 makes it easy to measure incremental changes in your body composition, allowing your trainer to tailor advice and even programs to suit your individual requirements. With over 40 data points collected from each and every scan, you are able to access a wealth of information at your fingertips.

View your individual scan history and harness the power in the data to keep you engaged and successful in your wellness regime.

Ask your club how you can join their next Evolt 360 challenge.


Ensure your height is correct
Ensure you have full contact over the silver tactile points on the machine throughout the scan process (especially palms)
Remove anything from your pockets as well as any activity tracking devices and cell phones
Don’t move during the scanning process
Ensure you are well hydrated prior to scanning
Ensure you haven’t taken any cell volumizing supplements or medications prior to scanning
Ensure you haven’t consumed any caffeine or caffeinated products prior to scanning
Don’t scan directly after a training session or when you are overly heated with a raised body temperature.

Why might I not be getting the results I would expect?

Not tracking results using the Evolt scanner. If you are not tracking your progress, it is like trying to find a destination without a GPS. It is extremely hard to reach your goals without direction. Scanning every 4 weeks is recommended for tracking progress.
Not standardizing scanning conditions.
Not tracking nutrition or measuring food properly. Nutrition is the first question asked when looking at follow up scans, if someone has a massive fluctuation between scans we need to know what they have been eating in order to make changes to their calories. If someone knows what calories they have been eating (following suggested macros goal on Evolt active app) it also helps coaches understand why their results are that way. If someone isn’t tracking their food intake, their results will vary
Not training with enough intensity or following a progressive program
Overtraining, not getting enough rest or recovery or inadequate sleep

Are you Super Shredded?

  • In athletic populations, where varying glycogen stores are likely throughout a training week, it is therefore likely that this will lead to some variation in detection of changes of fat-free mass in athletes as glycogen levels are likely to be affected by both nutrition, as well as the intensity, frequency, duration and modality of previous training sessions – even if the pre-scan conditions are standardized.
  • Some individuals who look very lean (especially endurance athletes) can hold more body fat than you would expect. This is because sometimes they carry more visceral fat mass. Visceral fat is strongly correlated with stress and cortisol, so even though the client may be quite lean (low in subcutaneous fat) their visceral fat may be quite high due to stress from training load etc.
  • Do you have a bodybuilding background and have previously used skinfold testing to measure subcutaneous fat? Skinfold testing is very dependant on who is taking the measurements and only detects subcutaneous fat. The Evolt 360 however measures both subcutaneous and visceral fat tissue which provides a more accurate representation of your body fat mass. Having high visceral fat is a risk factor and can lead to health issues.

Common Queries

I look better and my clothing fits better but my scan result went backwards.

Sometimes you can still look better and perform better, so the emphasis should be celebrating those wins but also looking at the circumstances around the scanning conditions if the result is negative.

If the scanning conditions are adhered to from the check list, then further investigation of your personal circumstances need to be addressed. It is fairly easy for people to be compliant in the first 14-28 days of a transformation challenge but steadily revert back to old eating habits in the second half of the challenge (despite full training and activity compliance).

It is also very easy for individuals not to properly track their food, ie. weigh out portions and unknowingly over consume some foods. If you aren’t tracking your food at all, start tracking using a calorie/macro tracker such as MyFitnessPal or similar. Self-monitoring food intake has been shown to improve the success of fat loss attempts and maintaining dietary changes into the future.[1]

In any event, Fat Loss phases are never linear and there will always be plateaus along the way.  Don’t focus on the numbers if you are visibly doing well. Stay compliant and the numbers will change in the right direction eventually.

You will see in the graph below how variable the changes are, however, they still trend in the right direction towards the long-term goal.

The human body is primed to survive and restore homeostasis (the body fat set point at which your body is most comfortable and will often return to).  Physiologically speaking, your body has certain processes to keep you from starving and support vital organs and hormones.  When people are in a fat loss phase and reduce calories, initially there will be a substantial change. After some time, there will be a metabolic adaption process which is when the body reaches a plateau (the metabolic adaption process is to prevent you from starving to death).[2]  This is why nutrition and training protocols need to change at some point in time during a fat loss phase to keep progressing in the right direction.

My body fat percentage increased but I look better

We commonly see individuals who might lose 5-10 pounds in weight, hence the smaller frame and fitting better in clothing, however, because the member’s weight loss was due to loss of lean body mass and not body fat mass, hence the body fat percentage increases due to the loss of lean body mass.

This is why we always suggest to concentrate on body fat mass rather than body fat percentage as the “mass” component will give you a better gauge of the actual fat lost and provide you with some data to adjust components of your nutrition or training plan.

Again, this is an opportunity to engage with your trainer and ask for advice on how you can reach your end goal. It shouldn’t be perceived as a negative, but rather an opportunity to make some adjustments and improve the next result.

My body fat percentage isn’t what I expected it should be

Firstly, Body Fat Percentage is very unique for everybody and no two bodies should ever be compared.  Everyone stores body fat differently due to genetic structure, gender, hormonal status and the amount of skeletal muscle mass held.

Body Fat Percentage also includes visceral fat mass, which is not visible like subcutaneous body fat, so people often confuse body fat percentage as being a measure of subcutaneous fat only.  For example, some endurance athletes who are quite visibly lean, can carry higher visceral fat mass and lowered skeletal muscle mass which will show a higher body fat percentage than they perceive. Just because someone looks lean, doesn’t necessarily mean they will have a low body fat percentage.

Unfortunately, the perception and expectation of body fat percentage for some people determines whether they are satisfied with their body composition progress. There are a lot of women who expect that they should be in the low 20’s or even under 20%, however the reality is that women under 20% are conditioned athletes and compete in physique sports anywhere from 14-20%.  Generally speaking, the healthy range is 20-30%, however, some women can carry higher than 30% body fat and still be very healthy, fit and in good shape. Men typically are in the healthy range at 15-20% but again, a lot of men can carry a higher body fat percentage and still be healthy, fit and in good shape.

Nevertheless, a first scan showing a high body fat percentage is only a starting point and should be used to measure progress (ensuring that lean body mass is retained or increased, and body fat mass is reduced).

I used another machine and got a different result than I did on the Evolt 360

All forms of BIA have been established as being identical in terms of the method of operation and the utilization of impedance measures that incorporate an alternate electrical frequency to determine body composition.

The Evolt 360 stands on a platform of substantiated scientific methodology that is consistent with all current evidence-based practice and uses the proper 5-point method to establish a result. Some brands only use a 3-point method so obviously those brands will show variable results.

The take home message is to always be consistent around scanning and that means using the same device all the time.  Some people may use their bathroom scale to compare with the Evolt 360, but the measuring parameters and technology are completely different so cannot offer a reliable repeatable measure of progress.

Body Transformation Success Stories
Body Scan Results


  • The Evolt 360 uses a scientifically validated test known as Bioelectrical Impedance Analysis (BIA). It is considered the fastest, non-invasive method of screening total body composition.
  • Bioelectrical Impedance (BIA) works by passing a safe, low intensity electrical current through the body via the tactical points on the machine (feet and hands). In very basic terms, the resistance to flow of the current determines the difference between muscle mass, fat mass (including visceral and subcutaneous), water and mineral.
  • The Evolt 360 advanced measuring system uses a 5-compartment model, which essentially provides a more accurate measure than a 1 compartment system (ie. Such as a single scale that claims to use BIA technology).
  • BIA was the science that was originally developed for the use in monitoring hospital patients after surgery, as well as in other areas of medicine, from Nephrology to Oncology, in Sports Science, Fitness, and Medical wellness, in Nutrition, Weight Management, Diabetes and Lifestyle monitoring.
  • BIA has been used for many years in the medical field to assess lean tissue losses in oncology patients.  It is widely used and validated in science as a safe, reliable and repeatable measure of body composition

Setting up the Evolt Active App






A Starting Point. Because the number one reason members quit a gym is that they don’t use it enough, Evolt gets them motivated by providing a baseline measurement of the overall fitness. This motivates them to improve and provides an easy-to-understand measurement of their progress.


Better Nutrition. By using the free Evolt app, your clients can easily monitor the macronutrient breakdown that is updated with each scan. It takes the guesswork out of a nutrition plan.


Easy Reporting. Through Evolt Insights, our cloud-based reporting program, trainers have easy access to member profiles, allowing them to monitor their workouts and progress. It also facilitates automated Club Challenges.


Recurring Revenue. Evolt 360 actually creates a third revenue stream after membership dues and personal training fees. Do the math: If you add just $20 per month to your base membership for one scan a month, each client adds up to an additional $240 a year — $4800 a year for getting as few as 20 clients on the machine.


Unique Lead Generation. You can take your Evolt 360 out of the club to special events. Think health and wellness fairs, senior centers and recreation programs! The lead generation opportunities are limited only by your staff’s imagination.


Training for Trainers. We don’t just send you a box and leave you on your own. Evolt provides a proven on-boarding program for all new clients to make sure everyone understands the process and the science. Your success is our success.


Backed by Science. Evolt 360 is the exact opposite of a one-size-fits-all product. Its science accounts for the unique and personalized characteristics of every individual. Just like your club should!


And one more thing: Scientific literature has written time and time again that there is no such thing as a direct measure of body composition — except in a post-mortem dissection of a cadaver. Scientific validation of BIA technology has proven the use of specific algorithms that consider age and gender to improve the accuracy of body composition measurement. The Evolt 360 takes that even further by incorporating five specific personalized variables – height, weight, gender, age and impedance – to provide the most accurate body composition measurement for any individual.
