I would suggest the fact that they can safely have a lower body-fat than girls can. Boys can acheive about a 9 or so percentage, whereas it is unsafe for girls to go under 10 percent. Also, muscle in boys is different from muscle composition in girls. Girls normally have smooth muscle, and boys will have rougher muscle. Another fact that you may or may not take for real, is the fact that God made man to be the leader and protector of his household... So, as the protector, he would probably be the more physically fit of the pair (Man and woman). God Bless!
