I checked your pics from your log (the DC thing) and your upper body looks completely untrained while your legs look semi-trained; I don’t mean this as an insult, youre a taller dude and obviously not posing properly. But yeah you look kinda like Artem (find his thread on this site) after his bulk – and guess what? He didn’t gain a commensurate amount of strength with the added weight either.
Not everyone is cut out to become “huge”. To get “huge” you should aim to have somewhat shocking lifts (free weight or machine) but not everyone has the ability to “get super strong”. PERMAbulkers get impressively strong while theyre adding all kinds of tissue, DREAMER bulkers end up benching well under 3 plates while weighing close to 300 pounds.
Basically you’re a grown man who’s BB shoulder pressing 150 pounds at 260 pounds??? I’m afraid the whole “powerbuilding” thing with a gallon of milk isn’t designed for you. Youre basically a 170-180 pound man walking around in a 260 pound body based off your pics and lifts. The good news is you’ll look great ripped at 180 or thereabouts.
Just continue lifting and follow a sensible diet plan with one caveat : pick one that does NOT include crap loading or all out bingeing or carbing up for an entire day. Heck do the AD, it will work as long as you limit yourself to a carb up for a SINGLE night (around 4 hours)
