When I lifted. I got up to 190ish last year. I haven't lifted in quite some time exctept for a few times here and there So I lost almost 10lbs of muscle. Hence why Im around 180. I still get decent workouts in because of having a manual labor intensive job but its not like hitting the gym I need to start back up asap. I didn't lose too much size that I had. Just a little in all spots. So no, it wasn't fat. I have such a high metabolism I've never really stored fat at all. I've had abs since Highschool 10yrs ago.
