LBM includes your muscles, bones, organs, and water. A higher LBM often correlates with a higher metabolic rate.

  • Crucial for tracking muscle growth in athletes.
  • More lean mass helps burn more calories at rest.
  • Strength training is the best way to increase LBM.
  • Helps differentiate between fat loss and muscle loss.
