In my opinion, I think I can be 16 years old, because I graduated from junior high school. At this time, the body is at the peak of development, and both bones and muscles grow faster. Doing more body-building exercises is beneficial to development, but we should pay attention to supplementing nutrition to lay a good foundation for the body.

I just graduated from high school and my body is not fully developed. I suggest not going to the gym!

Even if you go, don't do muscle exercise. Now, focus on practicing your explosiveness, flexibility and coordination! Let's talk about this muscle mass when the body is well developed!
