I see, over and over again, people switching their programming up way too soon. Everyone wants to gain as much as they can as far as size, weights, etc... but no one wants to stick with a program for longer than a month. We live in a society where everything is instant and when we don't get instant results in the gym we throw a hissy fit and switch it up because, "Its a problem with the program". I say bollocks, you being a gigantic weenie is the reason you are not getting results.
For the past year I adhered to the Conjugate Method of training(Notice I didn't say Westside here). You read that right, I followed the same exact protocol for an entire year and saw continuous results. Traditional/Linear Periodization says that you have to switch up training styles every 4-6 weeks to see results and I'm calling shenanigans. Now here is where people who hold the certifying bodies up as the gold standard are going to get butt hurt.
Let me ask you one question, "If your goal is to gain strength, what happens to your strength when you switch back to an "Endurance" phase or even a "Hypertrophy" phase?" It is going to go to crap. Stick with your programming longer. Now I'm not saying stick with a 5x5 for the rest of your life. Give your programming some time, seek the advice of people that are bigger, faster, and stronger than you. Success leaves trails, so follow them. Which leads me to my next point...
When seeking the advice of someone that has written programming for you, take it as it is. I see people trying to change up protocols that are tried and true all the time. If you write your own programming, by all means change it up. Let us take Jim Wendler's 5/3/1 into account here. Jim gets bombarded every friggin' day about questions about changing up his programming. He has written the program a certain way for a reason, he knows what he is talking about. If you think you're such a training guru write your own damned program and sell it. Give the programming a chance, wait three months, then if you feel as if the programming is inadequate, or there is something you want to change about it, do it! Wait another three months and compare the results to the previous training cycle's. If they are not as good as before, then you know where you went wrong.
Find what works for you. There is no golden standard when it comes to one method being vastly superior to another. Some people get better results from the Westside Template, others do better on 5/3/1. Hell, Doug Hepburn used his Program A/Program B protocol for years before he switched it up. Every person is different. If you are built to be explosive, using the Conjugate Method might not do you all that much good, but if you are slow but strong, the Dynamic Effort Day will do you some good.
All in all, JUST BE PATIENT. It took Andy Bolton almost three years to put 5 lbs on his deadlift when going from 1003 to 1008. You keep that in mind and you'll do fine.
