Anyways, I did find some quick searching and I found a verse in Scripture that does suggest that Samson was not a muscle type man like Arnold Schwarzenegger.
There hath not come a rasor upon mine head; for I have been a Nazarite unto God from my mother's womb: if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man. (Judges 16:17).
Now, if Samson did look like a body builder and or he was super huge and stuff, then how could he be weak like any other man? The short answer is that he couldn't be weak like any other man if in fact he was all muscular and looked like a big ole hercules type guy.
Does it say weak like any other "skinny man"?
No.
Does it say weak like any other "scrawny anemic man" ?
No.
WHO gets lumped into this general group of men?
ALL MEN.
The skinny ones are lumped in.
The fat ones are lumped in.
The BiG HUGE MUSCULAR ones are also lumped in.
ALL MEN are lumped into this phrase, "like any other man".
The phrase "weak, like any other man" is lumping ALL MEN TOGETHER, into one group.
God is saying ALL MEN, big and small, are the same.
It is saying, as far as God is concerned, ALL MEN ARE WEAK...
both the weak men, and the strong men... ALL ARE WEAK.
Since ALL MEN are lumped into this phrase, "like any other man",
then we have NO IDEA if SAMSON was skinny, fat, short, tall, or muscular.
We have no idea.
YOU CANNOT DRAW ANY CONCLUSION ABOUT HIS SIZE OR APPEARANCE FROM THIS VERSE.
THIS VERSE TELLS US NOTHING.
Even Arnold schwarzeneggerr, in his best days, was still "weak, like any other man"...
he had no divine super powers.
By God's standards, Arnold schwarzeneggerr was "weak, like any other man".
Samson, whether muscular, or scrawny, was still "weak, like any other man".
So, we still have NO IDEA what Samson looked like.
The phrase "weak, like any other man" applies to ALL MEN,
so it can't tell us what Samson looked like.
No matter how you slice it,
this verse TELLS US NOTHING about Samson's appearance.
We still have no idea if he was skinny, or muscular, or roly poly... we have no idea.
