Animal: I have three major periodization cycles in my yearly training. Each will last from 6-8 weeks. Six if I feel gains are slowing down and are not what they should be for what ever reason (bored). Eight weeks is the cut off period, as a max effort, even if I'm still making some progress. After each cycle is done, I will take a week or two off of training.
One cycle is GVT. Next is Power Rack training, including true (not breaks or burns like in BB'ing) partials, dead stops, lockouts, holds,etc (my favorite way to train). The third is general BB'ing/lifting. Rep's are usually higher, like 12 to 15 and as high high as 20 with Squats, BB Hacks, DL's, Hi-Pulls, etc. This is volume training but not in the usual sense. More designed towards the PL'ing/Olympic lifting workout style. Trying to increase total weight (LBs/ton's) lifted each workout. I keep an exercise log and try to beat the last workout in total ton's lifted.
When beginning to work into each new cycle I may be a little sore after the first workout or two, but nothing outstanding. When increasing the focus and weight during each workout I really don't feel any discomfort from training. I actually feel very hyped and on top of the world. Good Luck.
