- Less than 1% of my audience are PL.
- I am not a PL.
PL is not about "full body" or whatever - the ONLY thing that matters is increasing the 3 lifts; nothing else. If one does care about increasing the squat, bench and deadlift, he would PL. If one wants to increase other areas of his training, then he can do it any number of ways, but he wouldn't be a PL. Because then it wouldn't coalesce with his goals. I think this is where so many people go wrong: they aren't willing to give up anything to get their goals. It's a form of self-sabotage. But this goes well beyond this forum.
Just like training for sports isn't about benching X and squatting Y - it's about doing the things that needs to be done to be better at the sport.
Like everything in fitness/strength, things come/go and if you stay in this business long enough, you see the same ideas recycled and people screaming "THIS IS THE BEST!" Full body training has been around for a long time, fell out of favor and now is in vogue. 10 years from now, it will change. 20 years from now, it will be back in style.
In general, stuff like this doesn't matter that much: full body, splits, etc. You work hard, be consistent and have solid principles, none of the static matters. This happens with EVERYTHING -so all one does is stay the common sense course and evolve.
