Oh and you really need to learn how to perform these exercises properly, or you might as well stay home. If you don't you might even get injured.
Remember don't rest that long (1-2 min, and sometimes 2-3 min).
You should also get at least 8:30 hours of sleep. And learn how to control the negative portion of the rep(the way down), it is half the rep, remember that.
I'll give you some basics: I use a 3-4 month bulking cycle, more than that and you'll burnout, trust me I know from experience. The first thing you need to understand is that what works for some people will not work for everyone. However, there are only a few ways to do things right. You need to experiment and find out what works best for you.
The trick to gaining muscle is quite simple, your workouts should not exceed 60 mins. It is better to train 45 min, 4 times a week then 1h30min, 3 times a week. But here's the catch, you shouldn't rest that long between sets, 1-2 mins.
You might think that you don't rest that much between sets, but you really need to time it, you'll be surprised.
These are things that people never do or take for granted that would make or break a physique.
Warm-up: do 7-10 min low intensity before each workout, just enough to break a light sweat.
Strech: The entire body before working out, and the muscle trained in between sets.
Mind-Muscle connection: lifting your couch will build any muscle. Why? because you are not thinking of using those muscle.
Drink Water: you need to drink at least 1 gallon a day, and especially before and after working out. Pre-exhaust: For larger muscles (Chest, Back, Legs), you need to pre-exhaust. It means that you would do a couple of sets (20-25 reps) before your workout making sure you don't go to failure.
Pre exhausting:
Let's take bench pressing for example. The bench works the chest, shoulders, and tris. The problem is that your shoulders and tris will fail before your chest, and you will end up not working your chest to failure.
Examples: for chest: 2 sets of flat flyes, for back: 2sets of pulldowns, for legs 2-3 sets of leg extensions.
Post workout meal: Right after working out: 60-80g of simple carbs, 30-40g of fast absorbing protein(whey). 30-60 min later a full high protein, high carb meal."
