Damn, why so aggressive? I'm not ruling out the other stuff you wrote. I'm gonna make sure my bulk is cleaner. I just brought that up as an aside, because I was also working 6x a week for many months at a time, eating clean.
I would lift 3x a week fullbody, and do intense cardio or HIIT on off days. While cutting, and bulking.
I had some muscle, but even when cutting - whether a really low calorie cut, or a more reserved cut, I would always still have some flab with the muscle. I could never get that nice lean look. always something to grab on with a full hand
