How The BodyMedia for Exerspy Armband Works

Just tracking steps isn't enough.

To lose weight, it's important to have an accurate picture of your calorie burn. Using four sophisticated sensors, the Armband captures over 5,000 data points per minute — from heat and sweat to steps and calories burned — every minute of every day. If you take a walk, most body monitors (ours included) show a level of calorie burn. Take that same walk up Mt. McKinley or any incline and we'll show you a higher calorie burn. BodyMedia for Exerspy captures that important difference because our sensors measure more variables and give you the most accurate calorie burn.*

Data doesn't mean squat unless you can use it.

BodyMedia for Exerspy makes it easy. Just plug the unit into your computer's USB port each day to automatically upload info. Then simply log the food you ate via your computer or mobile device, and our exclusive Fitness Manager tool gives you a running report of progress toward your goals. This including steps taken, time spent in moderate and vigorous activity, nutritional analysis and sleep efficiency, as well as any personal bests.

The KARDIO Fitness Manager - a dashboard of your day

Upload your data to your computer where the online Fitness Manager analyzes raw data, allows you to log food and presents info in an easy-to-understand way so you can track your progress. The KARDIO Fitness Manager, our exclusive online tool, helps you learn about your individual calorie and sleep information, analyze that data, and manage and track fitness and weight loss progress. The system allows you to enter your personal body parameters, provides you with biometric feedback, and guides you to your goals. Then you will have a running report on progress toward goals, including calorie burn, steps taken, time spent in moderate and vigorous activity, nutritional analysis and sleep efficiency - all while tracking your personal bests.

Why We Use the Sensors We Do

Back in the day, when our founders were revolutionizing this entire category of body monitoring, they set some ground rules:

1. Create a device that could ACCURATELY measure calorie burn. "Sort of accurate" wasn't acceptable. "Kinda in the ballpark" wasn't good enough.
2. Don't over-engineer the device and throw in every sensor PLUS the kitchen sink.

So, they set to work to determine the minimum number of sensors that would provide the raw data needed to accurately predict calorie burn. They tried and rejected lots of sensors — some too big, some too expensive, some didn't give relevant data. After lots of engineering, analyzing and evaluating, they settled on the four sensors we now have — which together predict the most accurate calorie burn outside of a lab.

• 3 axis accelerometer
• Temperature sensor
• Galvanic skin response sensor
• Heat flux sensor

Using multiple sensors is what makes us different from other products in the market. For example the heat flux sensor measures the amount of heat given off by the body. This is energy that accelerometer-only products miss when calculating energy burn based solely on motion. BodyMedia uses four sensors to achieve our proven accuracy.
