Understanding the Skeletal Muscle Mass Index (SMMI)

**Skeletal Muscle Mass Index (SMMI)** measures the density of active locomotor muscles relative to height. Unlike body fat trackers, tracking your SMMI points directly to anabolic hypertrophy success, ensuring you are building actual functional tissue rather than retaining water or fat during bulk phases.

For men, a skeletal muscle mass index (SMMI) between 8.5 and 10.5 kg/m² is standard. Values above 11.5 indicate advanced muscularity.

Skeletal muscles act as the primary glucose sink in the body, directly lowering insulin resistance.
