Six-pack

A six-pack refers to the visible abdominal muscles, specifically the rectus abdominis, that become pronounced when body fat is low and muscles are well-developed. These muscles are segmented, giving the appearance of six distinct sections. Achieving a six-pack typically involves a combination of regular exercise—especially core workouts—and reducing overall body fat through a balanced diet. It's a visual indicator of strong core muscles and low body fat percentage, but it doesn’t necessarily equate to overall fitness or health.
