Share This:

The Apple Watch is a revolutionary piece of technology that has changed the way we interact with our devices. For years, it has been a great tool to track your fitness and health goals, but now it can do even more. With the help of the AURA Strap 2, the Apple Watch Series 3 through Series 7 can now measure body composition with Bioelectrical Impedance Analysis (BIA) sensors. This means that you can use your watch to calculate your body fat percentage as well as other important metrics such as skeletal muscle, fat mass, body water, and Basal Metabolic Rate (BMR).

For years, Body Mass Index (BMI) has been used as an indicator of overall health and fitness levels. While BMI is still a valid metric for monitoring one’s health, it does not provide an in-depth analysis of a person’s body composition. With BIA technology incorporated into the Apple Watch Series 3 through Series 7 via the AURA Strap 2, users can now gain insight into their overall body composition and monitor changes over time.

Using BIA sensors on your Apple Watch enables you to measure your body fat percentage with accuracy similar to that of a traditional caliper test or hydrostatic weighing. The process is simple – just attach your AURA Strap 2 to your watch, place both feet on the sensors at the same time for 10 seconds wile maintaining contact pressure firmly against each sensor pad. Once complete, you will be presented with detailed information on your body composition including lean mass and fat mass percentages in addition to total weight measurements.

The AURA Strap 2 also provides additional features such as sleep tracking and heart rate monitoring which further allows users to track their progress towrds their fitness goals while providing valuable insights into their overall health.

Overall, the incorporation of BIA technology into Apple Watches is a great addition that povides users more comprehensive data about their body composition than traditional BMI calculations alone. With this feature now available on select models of Apple Watches via the AURA Strap 2 accessory, users have yet another tool at their disposal to help them reach their personal fitness goals!
