I worked out at the gym 3-4 months ago and now i stopped and i thought its ok to get stretch marks but couple of months ago I helped my friends to move some heavy things and strech marks turned red i thought thats ok but now after 3 months they are still turning red like dark red whenever i lift something heavy or use arm strength to do something.

Its kind of looks ok in the pic but it is not its dark red
