All-new Body Composition and Weight trends: Insights that Lead to Progress

July 08, 2024

With WHOOP, you can now track your body composition and weight to get direct insights into muscle mass and body fat changes. These new metrics can help you make progress against your goals – and take control of your long-term health.

Weight is so much more than a number – and doesn’t always tell the whole story. You might still be making progress, even if a number on a scale isn’t changing. Understanding the composition of your body – meaning the muscle, bone, water, and fat your body contains – offers more than just aesthetic benefits. Metrics like HRV often increase as muscle mass increases, and as you decrease fat or reduce body size, there’s often a decrease in resting heart rate. Balanced body composition also has benefits like reduced risk of chronic diseases, cardiovascular disease, type 2 diabetes, and high blood pressure.

If you’re looking to change your body composition, whether that’s increasing muscle mass, decreasing fat, or maintaining where you are, understanding the components of your composition is essential. Lean body mass is defined as a combination of your muscle, bone, and water mass. Body fat refers to fat that functions as a source of stored energy, as well fat that plays an active role in body function. Changing your composition comes from adopting healthy habits, like consistent sleep, wake times, meal times, and exercise. A healthy balance of fat and muscle is key to improving your long-term health.

Body composition is unique to everyone, and there is a lot of variability. These are reported lean body mass averages in America by gender and age:

By incorporating body composition and weight data alongside WHOOP metrics, you’ll get a more comprehensive view of your health, and gain insights into how your body composition impacts your sleep, resting heart rate, heart rate variability, and more.
