I know the type of guy this GR-WTF is, total attitude in the gym and 75% of reason young guys trying to start out with lil knowledge need guidance NOT insults, even if he doesn't understand anatomy and your correct or SUPER CORRECT I understood what he meant I've been lifting for 10 in military and 10 power lifting while in law enforcement,
The young man wonder why his cut of his pec is not as defined as the next guy, couple of reasons
When a young man is in puberty amount of estrogen is being released and counterbalanced by testosterone, the more estrogen even with out working out results in a more defined lower line, if you will, then as the male body increases testosterone the pec developement, lower line stops.thats the genetic angle..
After that if a young man starts to work out at an early age all this can be enhanced either direction, but specifically the decline and cable fly will assist u in the form you have asked for in your question
Don't worry about what guys like this say they are typical gym rats usually well built but no greater than 5-9 in height and foresight
