Every young woman wants to look and feel her best. To achieve that goal, many work on toning their bodies and building muscle mass. But when is the right time to start working out to build muscles? Here's the answer:
When kids reach puberty, they start making the hormones that build muscles. Until then, exercise only tones their bodies.
If young women want to build muscle mass, they'll have to wait until after puberty. In the meantime, they should eat healthy foods and stay active. That will keep them strong and ready to start building muscle mass when their bodies are ready.
