#BicepsData

A new national analysis clarifies the average midarm circumference for men, offering concrete benchmarks that go beyond aesthetics. The data, drawn from the U.S. Centers for Disease Control and Prevention through NHANES, helps Thai readers interpret muscle health in a practical, health-focused context and provides actionable steps to improve upper-body strength.

Across age groups, average midarm measurements are around 32.3 cm for ages 20-29, 33 cm for 30-39, 33.3 cm for 40-49, 33.2 cm for 50-59, 32.8 cm for 60-69, 31.8 cm for 70-79, and 30.7 cm for those over 80. At peak development, this translates to roughly 32–33 cm in circumference. For Thai practitioners, these figures anchor training goals in realistic, healthy ranges rather than idealized poses seen in media.

A recent analysis has given fitness enthusiasts and health-conscious individuals a clearer picture of the average male bicep size, sparking discussions about what these numbers mean for overall health and strength—and how anyone can go beyond them through effective training. The newly collated data, derived from the United States Centers for Disease Control and Prevention’s (CDC) National Health and Nutrition Examination Survey (NHANES), provides concrete benchmarks for men’s midarm circumference across age groups. For many Thais invested in personal fitness or those concerned about muscle health in the context of ageing, these findings hold practical significance and present actionable guidance.
