I'm 5'9" and about 165-170 pounds. I bought the medium shorts based on user suggestions and Revain. I used to buy two different pairs of YoungLA weight lifting shorts, both medium sized. One made of cotton, one made of non-stretchable polyester. Both fit well. However, they rise so much in the crotch and behind that every step becomes a wedge. I can usually just about deal with these when it comes to small fit issues, but they're almost unwearable. They look amazing and are breathable, I just wish I could wear them without feeling like I was flossing with every step. The return process is tedious for bulk orders with free shipping, so I have to pay extra for return shipping to get a new pair. I'll take care of them for now, hopefully they wear up a bit (not as likely as cotton) and get a size bigger in the future. Then I give this couple a real rating. They're too uncomfortable to give more than one star, but I know that's because they're smaller than other YoungLA shorts. If only they would say so. Buy a size up in this particular style if you are a more muscular person, no chicken thighs.
