Who thinks they show hard work?

they show shrinkage or growth..not a great determinant of work though (some people get stretch markers faster than others)

I don't think they do TBH. I've made amazing progress and I don't have any stretch marks anywhere.

i agree..i think it depends on the person...i have gained ~40lbs and i'm only starting to get them where my biceps meet my shoulder

Definitely. My weight has fluctuated from 150 down to 135 and back up to 160.

Ive got no stretch marks and have lost 25 lbs + of fat. and packed on lean muscle.

then you have probably maintained your body volume, hence no stretching of skin to cause stretch marks haha

Depends upon the situation.

But yes, they very possibly could be a result of hard work.

They are from growing... not hard work.

Edit: if your growth is due to hard work, i suppose in turn you are having them from hard work.

I don't think so
i got ALOTTT bigger from like may to now and i just had little ones on each lat(right near the armpit) for about 2 days and i have like 2 reallly tiny ones on my right shoulder now
the only people i see with them are usually fat people(srs)
