- What is a bodybugg? What does it do?
The bodybugg® is the most accurate device on the market today for measuring calorie expenditure outside of a clinical setting.
It utilizes a patented process for interpreting calorie burn called "sensor fusion" developed by BodyMedia, Inc. This process involves collecting a range of body-data using multiple physiological sensors instead of a single sensor, which is what other calorie estimation devices such as pedometers and heart rate monitors rely on. It's this multi-sensor approach that enables bodybugg® to "see" the wearer's context (whether they are sitting, sleeping, jogging, walking, etc.) that makes bodybugg® such a reliably accurate device for calorie expenditure estimation.
The Physiological Sensors
Here is a list of the sensors in the bodybugg® followed by a short description of how they contribute to energy expenditure estimation.
Accelerometer - The accelerometer in bodybugg® is a tri-axis micro-electro-mechanical sensor (MEMS) device that measures motion. This motion can be mapped to forces (g-force) exerted on the body. By taking gravity and motion into account along with the other sensor data, the wearer's body context and true level of physical exertion can be accurately predicted.
Heat Flux - The bodybugg® also contains a proprietary heat flux sensor located on the side that measures the amount of heat being dissipated by the body via a thermally resistant material. In short, this sensor measures how much heat the wearer's body is giving off. Heat flux is an important parameter because the body tends to heat up the faster it burns calories.
Galvanic Skin Response - Better known as GSR, this sensor is comprised of two "hypo-allergenic" stainless steel electrodes on the back of the armband that measure skin conductivity. Skin conductivity is how much an electrical current can pass between two points on the surface of the skin and is affected by sweat due to physical exertion as well as emotional stimuli such as psychological stress.
Skin Temperature - Skin temperature is measured by using a highly accurate thermistor-based sensor located on the back of the bodybugg®. Looking at continuous measurement of skin temperature in conjunction with data collected from the other sensors can reveal the body's core temperature trends which are affected by the level of a person's physical exertion or lack thereof.
The data these 4 sensors collect, in conjunction with the wearer's specific body parameters (age, gender, height, weight) enable the most accurate estimation of energy expenditure on the market today outside of a clinical setting.
- A friend gave me their old bodybugg. What do I do now?
You will need to purchase a web-only program. With this you'll receive 2 bodybugg coaching sessions to help you learn how to use the program as well as a 3-month web subscription. During your first session, you'll just need to tell your bodybugg coach that you have an armband and he/she will make any necessary adjustments to your account.
- Is there a warranty that comes with thearmband?
Yes, the armband comes with a one-year warranty which begins the day you activate your armband. Please note: water damage is not covered by the warranty. The elastic strap is intended to last at least 90 days from purchase date, provided it is hand-washed and allowed to air-dry (do not tumble dry).
- Can I use the bodybugg system online without the bodybugg armband?
Yes. Actually the online program is the foundation of the bodybugg system. Based on your measurement changes, the system will determine your actual daily calorie deficit (or surplus) according to your one-week average. To help you stay on track without the bodybugg armband, there's an easy-to-use food logging function so you can keep track of calories consumed. There's also an exercise calculator with hundreds of activities to choose from to determine how many calories you've burned. Through the bodybugg online interface, you can customize and print menus as well as view and print your exercise programs. There are also several informative knowledge builders, tutorials, newsletters, and daily questions and answers to help you stay on track. Check out www.myapex.com
- How accurate is the bodybugg?
The Armband has been clinically validated to be over 90% accurate when determining calorie burn through the entire day. More specifically, a recent independent study tested the Armband in real-life situations. Participants engaged in "free living" activities, including brisk walking, running, bicycling, sedentary activities, home activities, home repair, occupational activities, strength training, and ball games. The study compared the Armband to a $40,000 "portable oxygen analyzer", the gold standard for measuring calories.
Total Calories for free living activities: mean error <10%.>
Total Minutes of exercise: mean error <5%.

- What is calorie balance, deficit, surplus?
Calorie balance is the difference between calories consumed and calories burned. Your caloric burn value is determined by the data from the Armband, off-body estimates and any manual activities that have been logged. The caloric consumption value is determined by either the logged meals or body mass changes. Calorie deficit = when you have burned more calories than consumed. Maintaining a calorie deficit over time is a key ingredient to weight loss.Calorie surplus = when you have consumed more calories than burned. Maintaining a caloric surplus over time is a key ingredient to weight gain.
- Can one bodybugg be used by multiple people?
No, we do not recommend multiple users on one bodybugg® armband. Each armband is linked to a particular bodybugg® online program. Having multiple users wearing the same device simultaneously would negate the accuracy and effectiveness of the overall bodybugg® program.
- Do I have to wear the bodybugg device 24 hours a day?
We recommend wearing the armband as much as possible during waking hours. The more you wear your bodybugg® , the more accurate and effective you will be at maintaining your calorie deficit goal. During times of low activity (such as sleeping), the program will estimate your calorie burn at rest, based on your body parameters, so it is not 100% necessary to wear to sleep. We advise removing the device for at least an hour during the day to allow your skin to breath.
- Why is the bodybugg more accurate than a pedometer?
The bodybugg® is more accurate than a pedometer for calculating calories burned because it is "watching" your body from four different perspectives. A pedometer only measures steps. In addition to measuring motion and steps, the bodybugg® is able to see how much you are sweating, your skin temperature and the rate at which heat is being dissipated from your body. These additional physiological parameters give the bodybugg® a more complete picture of what your body is doing and its level of exertion, all of which means a much more accurate estimation of your calories burned.
- Does the bodybugg measure my heart rate?
Not at this time. While heart rate information can be useful, it is not necessary to accurately measure total calorie burn. In fact, there are many factors, such as prescription drugs, cardiovascular disease and abnormalities, which can affect heart rate, making it more difficult to obtain an accurate overall assessment of calories burned.
- Can I get it wet? Can I wear it swimming?
The bodybugg® should be protected from water and should be removed before showering, bathing or swimming. The armband should not be worn in saunas or steam rooms.
- Does the bodybugg armband track what I eat?
- Will the display work without the armband? What does the display do?
No. The Display provides a visual output for your Armband. It is not a monitor in itself. It will only update and present your Armband data when the Armband is on your arm and "on-body" (sensing). It shows calories burned, time, steps, calorie goal, what you did yesterday, and trip. Also has a light on it. Note: You can still use the Display as a time piece when the Display says "not in sync".
- How much does it cost?
That depends on if they're running a sale. They are regularly $249 but right now they are on sale for $199. The optional watch display is $99 and worth getting. The online subscription has various plans (3 mth, 6 mth, monthly, yearly). The monthly is usually $14.95/month but right now is on special for $9.95/month. I got my 1 year subscription for $99 but the renewal for the year is $79.95.
Elizabeth Sherman also leases them for with the online program for $25/week. Kind of a try before you buy type thing.
Yes, I love my bodybugg. :)
