Ok, so I go to the gym and work out on a trainer, then do a bunch of exercises (on the mat, and in the gym). I'd like gym shorts where there is padding (or at least chamois and smooth seams) without looking like I have a potato in the back of my pants. Maybe this is just a specific brand of shorts. I'm using my old-school chamois shorts. I'd like regular gym shorts that have a liner and smooth seams. Any makes or models that are better than the other?
