There is no one-size-fits-all answer to this question, as preferences vary widely from person to person. However, research and surveys suggest that women tend to find men with fit, athletic bodies the most attractive.
These men are typically in better shape than average but not as lean and strong as bodybuilders. A "dad bod" can also be appealing to some women. Additionally, women are often attracted to specific physical features, such as arms and abs, as well as overall health and fitness.
Ultimately, the most important factor for a woman is finding someone who is confident and comfortable in their own skin.
