i've been training 5x5 past 4 months. I really loved this training since it's the only one which gave me noticable results. I did't pack much muscle mass but I've had incredible strength results. Now I'm stuck on 100kg bench, 150 DL and 120 squat for last 2 weeks. Squats keep slightly increasing but I'm frustrated from my bench and DL. I train rows, overhead presses, chins, pullups and barbell curls which stopped progressing too. Is it possible that I plateaued that soon? I'm 24 yrs old. Problem is I eat shitton of food already (~3500 kcal) and there is not really time to add another meal (work + school). I have much stress from university recently but that won't stop anytime soon. I sleep 7-8 hours.
So could any advanced lifter give me advice, please?
a) Should I eat more and continue 5x5?
b) Should I move to some crazyass bodybuilding training with 10+ reps to pack on mass, and then move back to 5x5?
c) Other options?
