Use boundary

Calculation path

The selected Boer population equation applies different weight, height, and constant coefficients to estimate lean mass.

Calculation path

LBM = 0.252W + 0.473H - 48.3.

What you provide

What you provide

  • Equation sex option: Choose the published coefficient set used by the selected population equation.

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

This is not DEXA, air displacement, bioimpedance, or a diagnosis; body composition and equation fit vary substantially.

Planning and fitness outputs are estimates. Confirm measurements, product specifications, site conditions, health context, and professional requirements before making purchasing, training, medication, or care decisions.
