Is a lack of natural muscularity and size compared to others

Yes

>>42581970
No

>>42581970
Maybe

>>42581970
probably due to lack of overall development, as in, you never fucking played or did any actual physical activity.

its due to being a lazy weak willed sack of shit.

I dont think people realize how much being active throughout your childhood and teens translates to building muscle and strength later on. GIves you a huge headstart

i dont think it's genetic cause my family are pretty fit dudes whereas i'm 5'9 and like 100 pounds at 20
I blame my shutin lifestyle and my constant naps

born on a farm so i helped around all the time plus very active childhood. still 5'8 with girly wrists and small frame

Did you drink that estrogen infested cow milk?

Beyond testosterone, myostatin and frame, are there any other significant genetic factors that determine muscularity?

really no clue what happened. my dad is 6'4 and mom is 5'10. looked promising early on because i was already 5'8 at 13 and taller than majority of my peers by at least a head but that was it. haven't grown an inch since
