As a beginner, you need very little stimulus to create an adaptation. Doing more isn't going to make you grow any faster; it's just going to slow your progress. You must be patient and let the body grow.
After your warm-up sets, three working sets of five reps on the bench, squat, and lat pulldowns are all you need to stimulate the body enough to grow. It's boring, but enjoy it. You'll wish gains came this easy when you're older and stronger. Below is an example of this training method:
Repeat this model from week to week. It's seriously this simple. Lift, eat, sleep, and grow.
You might not even need to spend an hour in the gym at this point. And it might not feel like you're getting shredded or putting in hard work. Why? Because you just aren't strong enough to make it hard. Benching 95 pounds for 3 sets of 5 is going to take about 10 minutes, warm-up included. Same with a 135-pound squat.
All the more reason you should focus on this and get away from being weak. This can be the hardest stage of training. It's bland, it's boring, and you don't feel like you're doing a lot. Just focus on your numbers for motivation and watch them go up because this is the quickest way to escape weakness.
Deadlifts and overhead pressing should eventually be added after a couple of months of this basic beginner stage. They simply just aren't that important right now.
