I disagree on that. If you wanna get big you have to eat and gain weight and that's not debatable. Progress in the gym means only a fraction of progress regarding bodybuilding.
I've hit 270kg deadlift, 240kg squat and 180kg bench as a natty and since i got on gear i'm nowhere near that strong because i don't chase strength anymore. My physique has changed drastically though.. To be clear, from the moment i started gear and up to this day yes i'm a litle stronger, but this wasn't my goal. It just happened inevitably.
If you are obsessed with strength and progression while bodybuilding you'll end up tearing muscles and destroying your joints. I'm 37yo and doing this for 21 years, i have already a good number of injuries and i'm not planning to increase them. Not everyone has to train like jordan peters to progress. IMO strength progression is mandatory only in the first years being on the game, then when you reach a good level of strength i guess it's time to incorporate a different and smarter approach.
A 1000kcal surplas that was increased steadily, so that amount was my peak for the last weeks and not from the start obviously. My protein and fats remained the same and i just added carbs. Started with 400gr and ended up at 720. This is like 1300kcal more but i was backing off at non training days and my weekly net surplas including my one cheat meal was something like 7000kcal.
Then my guy i don't have to say anything else, if you did what you're saying and with extra calories you accrued enough fat just find another way to progress and if that's going with small surplas then by all means, obviously it's the best thing for you. This is unfortunate but we all have to find what works individually.
