Long term training cycle

I've been doing some reading and it seems that periodization is one of the most effective ways to increase power,strength,size and endurance. Reverse linear periodization seems to me to be a good idea, but exactly how much time should be spent on each stage is something I'm unsure of.

For those of you who do periodization, or any kind of long term training, what would you recommend? Keeping in mind I'm not looking to enter any competitions, are there any good annual plans available online for both strength and muscle size?
