The program I am following is stickied on the biggest bodybuilding site in the world. In the 15 months since it was created, it's had close to 500K views and 5K replies. If it was rubbish it would have been torn to shreds by now and forgotten. Instead it's the most recommended program on there for beginners by Mods and old timers who have been lifting for years (even over the usual Stronglifts and Starting Strength).
It's nothing ground-breaking, just a simple A,B,A,B... linear progression program using compound exercises the same way they have been used for decades. The only difference is he's added rotator cuff work and instead of the usual power cleans and squats on the B-day he put front squats and RDLs for quads and hamstring development, which would not otherwise develop as well doing just back squats.
It's acknowledged in the thread that this is the best version of the programming, and he just allowed the deadlift + leg curl substitution because every 5 posts someone asks if they can do conventional deadlifts instead of RDLs.
The creator has also made other programs for intermediate and advanced lifts, as well as to correct kyphosis and lordosis (all put together in this thread
"Fierce 5" Comprehensive Program List).
I'm not saying this is the greatest program every made, there are many ways to get strong, we just have to choose one that we will actually stick to. I don't want to sound like some know-it-all either, I am still a noob, I have only been lifting for 18 months and my lifts are pathetic. I'm sure most of the guys in this thread know way more about training than me, but after going through a bro-split, Starting Strength and AllPro, I've decided on this one being the one for me.
I just try to educate myself by reading articles posted by much more knowledgable people than I, since I don't want to do something like ruin my shoulders or my hips by doing a program which is unsound. Based on that, I believe this is a good program for me personally, so I am going to run it until I am intermediate and then I'll switch to 5/3/1.
