Ok so im not talking about raw denim thats going to naturally stretch with wear. im talking pre-washed jeans. solid denim, with not much give to it. (in my particular case its a pair of diors that i slightly grew out of) the jeans fit but they could be a little more comfortable. whats the best way to get these to loosen up? people say to just put them on and do lunges and squats lol, any other techniques?
