During preschool years, boys often exhibit larger muscle mass compared to girls, which contributes to their physical development. This characteristic arises from biological differences in growth patterns, with boys typically experiencing a greater increase in muscle bulk and overall strength as they grow. This muscle development can lead to boys being more capable of engaging in activities that require strength and power.

It's important to consider that while boys may have bigger muscles, this does not necessarily correlate with advances in fine motor skills, physical maturity, or specific balance and hopping abilities. Fine motor skills often develop more distinctly in girls, and physical maturity involves various factors beyond just muscle size. Additionally, balance and hopping can vary among individuals regardless of gender. Therefore, recognizing that boys generally display larger muscle sizes is crucial in understanding their motor development characteristics during the preschool stage.
