My boyfriend is very in to working out and lifting weights. But he stopped after he realized that because he was pushing himself and that his skin is a little weak that he was getting stretch marks near his arms on his chest and back. He's asked me to help him to find some possible methods to either lessen the look of the ones he has or to help prevent new ones from appearing because he wants to weight lift again. If any one knows of any good products or methods than please let me know! Thank you!
