So i’m 20 years old 180 pounds (82kg) and 6 feet tall(182cm) i have been lifting for 4 years but last 2 years have been serieus. I got my lifts up to 2 plates bench 3 plates squat and 3 plates deadlift which is also pathetic.

But now i can’t get stronger in any lifts or isolation, and when i do i get stronger, i get weaker again soon after.

I have been really consistent for like 2 years with my workouts and diet i eat around 4000kcal - 4500kcal a day and also been consistently gaining weight.

So i do everything in the book right, eat enough nutritious whole food with enough protein and calories, train 5x a week heavy compound focused workout routine and trying progessive overload every workout and sleep 7-9 hours a day with enough recovery.

What the fuck could it be that i dont get stronger, while a friend i train with that eats like shit sleeps 4-5 hours most days and doesnt take it seriously literally gets plates stronger?
