Some fitness advice?

i am a male and is training to become big. they say if you want to become big, you should lift as heavy as you can? but the downside is if i do that, i feel extremely tired after that. For example, when i do barbell bench press, maybe i do around 12.5kg on each side (10 reps for 3 sets). i dont feel too tired and i can still feel my muscle sore. However, if i really want to, i can still lift up to 15 kg on both side (same 10 reps for 3 sets). That will make me feel really tired for the rest of the day and very sore muscle.

which is the correct weight that i should take? thankyou.

More weight, less reps for size; less weight, more reps for endurance. You need both.

And by the way, sore is fine if you're still starting out but if you're lifting routinely, you shouldn't ever be sore again. Just remember to give muscle groups 48 hours to rest so if you plan to lift every day, alternate excercises.

Work on a level which isn't to hard, so stay with the 12.5 kg but do more reps I'd go for about 10 sets of 10

Hell do it, you should lift as heavy as you can with good form, yea? It only means you aren't fueling yourself through meals as hard its required , Buy pre workout or add carbs in your diet
