How to Measure and Track Bone Weight, Lean Body Mass, and Other Body Composition Metrics

You can track a variety of body composition metrics—including bone weight, lean body mass, muscle mass, and more. While tracking these is optional, doing so can offer valuable insights into your health and fitness progress over time.

How to Measure These Metrics: To obtain these values, you’ll need a specialized smart scale, typically one that uses Bioelectrical Impedance Analysis (BIA) technology. These types of scales are often found in gyms, doctor’s offices, or can be purchased for personal use.

For example, certain Tanita scales can provide the following data:

• Body Weight
• Body fat percentage
• Muscle mass
• Physique rating
• Bone mass

Other smart scales may also measure:

Resting heart rate

Hydration levels

Visceral fat

Metabolic age (varies by model)

Syncing with Tracking Platforms: Many of these measurements can be automatically synced to your tracking tools through integration with popular health devices, including:

Fitbit

Garmin

Withings

In addition, third-party apps can share this data via indirect integration with health platforms such as:

• Samsung Health (Android)
• Health Connect (Android)
• Apple Health (iOS)

Once connected, your device data will sync seamlessly, allowing you to track advanced body composition metrics without manual entry. This helps ensure more accurate insights and saves time.
