My friend told me that I was a good age to build muscle. I didn't know what he meant by that at first. He said you can't build muscle as fast when you are in your 30's. Is this true? I figured most people could build muscle until they were in their 50's or older. Anyone have any information this?
I think what your friend meant was that at your age your body is fully grown into your man body (vs. teenage body of a 17-24 man, some grow faster some not) anyway the thing about testosterone is true you have less testosterone than a 17 but this shouldn't stop you from having great workout and seeing great gains.
