I personally like being lean, because that's how I've always been. However I was dieting all summer and recently have been eating a lot of everything. Pie, ice cream, spagetti, hamburgers almost daily, chicken, hamburger helper and all that good bulky stuff.
I have completely lost my 6pack and I look pretty bulky now but thats okay. I plan to do one huge bulking cycle this winter then lean out and cut before my summer cycle which will be a lean bulk.
So Lean bulk for sure. Its nice to have your shirt fit tight so people know you workout, but It's also nice to have a 6-pack and striations in shoulders!!!
