Yes boys do have more muscles than girls, and as a result of that an individual boy is much more often than not physically stronger than an individual girl, and that is why boys are physically stronger than girls. You see when boys & girls go through puberty, the boys will naturally have much more testosterone in their bodies than girls, and due to all the extra testosterone the boys will as a result of that naturally develop more & stronger muscles than girls during puberty so by the time that boys & girls have finished going through puberty the boys will end up being physically stronger than girls, with bigger and stronger muscles than Girls.
