When does muscle grow during puberty?

Question

For most boys, at what point do their muscles start to develop during puberty(I'm not looking for a specific stage....moreso like what else is growing/changing at this point).

Answer 1

You are not going to gain muscle by getting older or going through puberty. You need to lift weights and eat right in order to gain muscle.

Answer 2

everything is growing and changing all thru puberty, 24/7.
