yo guys, ive started noticing some small stretch marks up near my butt on my hams, and a couple on the side of the ass...i havent gained or lost a lot of weight at all, so im not sure what this could be from. Ive went from about 170 to 185 in 5 months of training...any havent picked up barely any body fat...what should i do? i dont want any more...only possible thing i can think of is that i do very deep ass to the floor squats, could this be a prob?
