a. they have more muscle fibers than men
b. they have thicker muscle fibers than men
c. they have lower testosterone levels than men
d. all of the above

Respuesta :

Females who lift weights are not going to develop large, bulky muscles because  they have lower testosterone levels than men . Correct answer: C

Testosterone is a sex hormone that regulates sexual development, muscle mass, and red blood cell production. It supports muscle, strength, and energy. Women produce testosterone too but their level is lower than men.
