Do what he says but don't do the same exercises for more then 5/6 weeks or your body will adapt and it won't get any bigger.
35 kg in bench press it's good because you skinny and don't have that much strength, but it's only good if you are doing right, if not low the weights, first thing in any exercise it's doing the technique right, weight come after.
If you wanna get bigger you have to count the calories you eat (good calories btw), it's pretty simple if you eat more then you spend you grow if you have a deficit calories you lose weight, you can use some app for 2/3 weeks that will help you take some knowledge of what you eat and how many you need, I recommend myfitnesspal, it helped me and I don't need it anymore because after a while you get some sense about portions and calories.
You need to pay attention on macro nutrients too and that app help you with that too.
And remember that any person who lifts hard started somewhere, take your time and your path with patience, it's not the same for everyone but do it right and the results will come, don't rush it or you may have some kind of injury that can cost a lot of days of training
