| Summary: | <i>Background:</i> Choreographic group-based fitness classes are the most common type of physical activity practiced by women, being a viable and sustainable strategy to improve general health. Thus, the aim of this study was to analyze the effect of a 16-week healthy lifestyle program, based on choreographic fitness classes, on cardiometabolic health-related anthropometric indices and metabolic blood profile among overweight sedentary women. <i>Methods:</i> A total of 50 overweight (Body Mass Index = 27.68 ± 1.19 kg/m<sup>2</sup>) middle-aged women (39.73 ± 7.41 years) were randomly assigned to an experimental exercise group based on structured choreographic fitness classes (CFC) with the Zumba Fitness program (3 days/week; 60 min/session) (CFC = 30) or a non-exercise control group (CG = 20). The anthropometric indices (waist circumference, waist-to-height ratio, a body shape index, conicity index, abdominal volume index, and body adiposity index), blood pressure, glycemia, and blood lipid profile [triglycerides (TG), total cholesterol, Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL)] were evaluated pre- and post-intervention. <i>Results:</i> 40 participants competed the pre/post measures. Post-intervention, the CFC group (n = 25) presented a significant improvement in all anthropometric indices as well as in TG, HDL, and LDL as compared with the CG (n = 15). <i>Conclusion:</i> A 16-week healthy lifestyle program based on structured choreographic fitness classes with the Zumba Fitness program (3 days/week; 60 min/session) could significantly improve cardiometabolic health-related anthropometric indices and the blood lipid profile in overweight sedentary middle-aged women.
