Actually it's quite simple, it's best to start skinny as f***, like all bones at 11% bodyfat so you can bulk for 1.5-2 years before you need to cut.

Second, if you fat or chubby... maybe got tummy abit and at 18%-25% bodyfat, but malas to do an initial cut before training, you can eat at maintenance (keep weight constant, it's called a recomp) and train for 1.5 years until your bodyfat % reaches 11%.

Third, you can cut and become a super skinny faggot skeleton before start training, so you can do the great 2 year bulk.
