Eric Horst's books detail out a macro-cycle system thats weeks endurance building (takes the longest to build up but lasts the longest), 3 weeks of Power, 2 weeks Power Endurance, and then a week off, following by crushing everything. Can't say I've had the patience for it, but he and his kids are wicked strong so.....

That one also has a bunch of additional stuff on diet, etc. That said, you ask 10 people, you'll get 10 answers.
I have the Falcon Guides "Training for Climbing" and it's really helped me to create a systematic approach to getting stronger. Lots of exercises and stuff, would definitely recommend it
What are you trying to get out of your training? Overall, I've found this book very helpful in getting better at climbing. But you might be more interested in other Horst books, like Conditioning for Climbing depending on what your goals and/or focus is.
this one is my favorite
