Lean Body Mass Improvement

Meaning

Lean Body Mass Improvement is a physiological objective focused on increasing the mass of non-fat components of the body, which includes skeletal muscle, bone, and water, but is clinically centered on the accretion of metabolically active muscle tissue. This improvement is a critical metric for enhancing metabolic health, physical strength, functional independence, and overall longevity, as muscle tissue is a primary site for glucose disposal and energy expenditure. Achieving this state requires a coordinated strategy of resistance training, optimal protein intake, and the precise modulation of anabolic hormones such as testosterone, growth hormone, and insulin. It is a vital component of a comprehensive health and anti-aging protocol.
