So what you are saying is, you dont do traditional "workouts" like cycling, running, weightlifting? I started bodybuilding when I was in my early 20's in the Air Force. I was I also in Tae Kwon Do for about 3 years in my early 20's. I played sports throughout school as well. I converted to crossfit from normal body building back in 2012... I'm no little guy either, deadlift 505, bench 350, squat 405, strict press 245 overhead, ***** 205, and I'm a decent runner (not my strength). Point is I'm no rookie myself. I've been around the gym for a long time and have watched people that workout, especially only cardio, and they dont develop musculature in their legs for the most part. Olympic marathon runners look like frail weaklings and they arguably work their legs, so to say, more than anyone. On top of all this, not everyone's body will react to stress the same. Some people are toned without doing jack, some workout and workout and dont get it.
