Defining “Ideal Abs” Through a Crowdsourcing-Based Assessment

Abstract Background There were almost 12 million nonsurgical cosmetic procedures performed in the United States in 2016, which represented a 12% increase from the previous year, and popularity is expected to continue rising. Furthermore, nonsurgical fat reduction and body contouring have experienced a dramatic increase in popularity among both men and women. However, there has been very little work focused on the public’s perception of the ideal abdominal muscles. Objectives The authors sought to analyze patient perspectives on ideal abdominal contours and attitudes towards methods of improving the appearance of the abdomen. Methods A prospective cross-sectional study of 718 random volunteers recruited through Amazon Mechanical Turk was conducted. A survey instrument was administered to all study participants to assess the importance of ab symmetry, pec muscle definition, serratus muscle definition, and natural feel. Results Study participants across all ages, gender, ethnicity, and marital status indicated that a 6-pack was the ideal abdominal muscle count. They also rated the symmetry (61.06 ± 1.87) and natural feel of abs (60.72 ± 1.75) as the 2 most important aesthetic features in consideration of ideal abs. Study participants who reported exercising more than twice a week expressed a greater interest in nonsurgical procedures to achieve ideal abs (P = 0.007). Conclusions “Ideal abs” are 6 in number, symmetric, and feel natural. Millennials are much more willing to consider nonsurgical options to achieve ideal abs instead of surgery. Individuals who maintain a high level of fitness are, interestingly, more likely to want ideal abs and nonsurgical methods to achieve them.
