How many titles have you won sir?
Professional Bodybuilding is (mainly) about two things. Genetics and Steroids.
Some people grow like weed and some don’t.
I trained with a lot of people in my home-gym.
Everything was the same, but the muscle development was completely different.
How could Shawn Ray look like this with 22 Years of age?

I could do what i want, i would never look like him.
If a pro has a weak body-part it never gets better.
Think about Markus Ruhls Trizeps, why it did not get better?
There is no secret, it‘s genetics, and most of the time pointless to discuss with a pro.
(this is true not only for bodybuilding.)
You should always strive for the best. (like a lot of people here do, they are just missing the pro-genetics)
