Not sure where this question fitted so I threw it in Off Topic. Lately been noticing some weird marks on my biceps that look like stretch marks, but I’m confused why they’re there because my arms definitely haven’t gotten that much bigger - it’s not like I’ve suddenly gotten (or ever been) super fat or super swole so I was surprised to see them.
Anyway that got me thinking about possible reasons. One idea that I had - is it possible to get stretch marks from the pump? Surely the fact that your skin is getting stretched out like that - your arms might get up to an inch bigger in some cases - could lead to stretch marks?
What are your thoughts? Have you ever had stretch marks from lifting?
