I work out with a trainer and "foam roll" as well, as you describe. I am seeing improvement, but my case was pretty mild to begin with . . . I wanted to head it off before it got too bad. I truly believe in weight training and yoga/stretching/pilates combined. I work out with a trainer with heavy weights (squats with a 20 lbs dumbell in each hand or 50 lb bar or leg presses with 75 lbs) and have never gotten bulky, just very nicely shaped muscles. After lifting, I foam roll. Then I do a "yogalates" class once a week. I dont know whether there is any scientific data, but I am convinced that weight training and deep stretching is the way to go. Not sure you could ever get rid of all of it, just create a more toned and tight appearance.
