Well, i can see what you mean but...
I think a lot of the time when people are on here talking about needing to take a cutting cycle it's because their last cycle or two was all mass oriented...Even if that isn't it, I really think some people are more predisposed to gain wait and therefore losing it is hard! I wouldn't know because I can eat whatever I want and stay at around 11%!!! I feel lucky as hell but at the same time it is harder for me to bulk up. I guess its a trade off, with people in the middle of the road being the lucky ones. Again, you are right that anyone can lose bf %, it's just harder for some than others.
