So I thought it'd be a good idea to get a thread going that's a safe place to admit those things you strongly believe but would get you seriously flamed if you ever admitted them in a forum.
I'll get the ball rolling with a few:
I think your training for a cut should absolutely be different than training for gains. Different goals require different focus.
I actually believe there's merit to training small muscle groups after a bigger one in terms of optimal growth, i.e. delts after quads, bis after back, tris after chest, etc. v. arms day or delt day
I fully endorse IIFYM.
I'll probably have more to add later, but wanted to hear some of yours. And as the title indicates, let's keep this place free of flames.
