You mean dehydration is good for looking strong/ripped? Having to do a water cut with 2 hour weigh-ins is the bane of my powerlifting existence. It's hard to rehydrate enough before squats start and not be bloated. But that said trying to walk around always looking your best is going to be fucking tough. Not having glycogen to run off of like you said is going to hinder any sort of strength you have but damn you'll probably look good doing it. I think this is where a pretty good distinction between instagrammer and athlete can come in. Look at Sadik right now. He's big, puffy, definitely not looking his best but he's showing there is a process to get to where he is going. (The new classic physique division) Now the guy in the article if he wants to get stronger and keep the same body composition its going to take a long time. Not having a calorie surplus makes it near impossible. And if you want them to help move a couch they'll be so drained they won't be any better help than a normal person.

Hopefully my point came across there between the vanity instagrammers and athletes who can seem similar.

But that is Zydrunas Savickas one of the better strongmen around right now next to Brian Shaw and Hafthor Bjornsson (The Mountain in GoT). I lift with a strongman at my gym and it is so much fun when I do some of their workouts. If you need someone to help you move they're the ones, if they can lift a few hundred pound atlas stone, they can lift an armchair for you!
