Training and eating, over a long period of time has to have a "completeness" to it.
If you get trapped into a particular mindset, or dogma, then you're going to eventually sell yourself short somehow.
For powerlifters, they often shun "bodybuilding" because it's "stupid" and "no one cares how big my biceps are when I lift X amount".
Bodybuilders will often say shit like "no one cares how much I lift when I'm on stage."
Technically, that's true. However understanding how all training methodologies can help you is a trait we should all learn how to develop.
I spent the first decade of my training mainly doing bodybuilding style work. And while my absolute level of strength was never developed, one of the reasons I feel like I am just hitting my peak in terms of strength is because of all the years I put in to build muscle mass. So the last 8+ years have really been spent training more for absolute strength, and developing my technique.
As a result of that, when I go back to doing big compound movements for reps, I move more weight for more reps. I also train "bodyparts".
This is not an ugly word.
People need to get out of this mindset that bodypart training is a bad thing. When Dan Green decided his squat sucked, he realized it sucked because his quads weren't big enough. So he grew his quads using hacks and front squats, and guess what? His squat grew with them.
A smart lifter knows that powerlifting and bodybuilding can indeed compliment each other.
Train for strength AND muscular development. This means not persecuting a training style or method. Bodybuilders have this whole "mass" thing figured out. Powerfliters and strongmen have this whole "strength" thing figured out. Instead of being close minded or dogmatic about one because you think it's "silly", take what is useful from it to get better.
Just because you decide to do some bodybuilding doesn't mean you have to slather salad dressing all over yourself and pose in a banana hammock. Just because you decide to do some powerlifting doesn't mean you have to wear a beanie and get fat.
Focus on the paradigm that makes up those training methods and how they would benefit you in the long run. Then if you decide to slather on the Italian dressing or sport the beanie, you'll be ready.
