(Note that multiplying your bodyweight by 20 results in a high calorie estimate specific to building mass. Many maintenance calorie estimates are closer to body weight multiplied by 15. If the result of multiplying your bodyweight by 20 seems incredibly high given what you know about your body, you can err on the conservative side and multiply by 16-18.)
Of course, no one was born pressing 500 pounds or squatting 700 pounds – it takes time to build this kind of strength. Assuming your form/technique is in place, you'll want to incorporate some low reps and heavy weights into your program. For example, do 10 sets of squats for 3-4 reps each, or 8 sets of 5. In other words, in order to build strength, keep your weight heavy and use low reps for a high number of sets. Squatting your bodyweight is a bare-minimum requirement for a beginner (or twice your bodyweight for an intermediate-level lifter).
22. The muscle building topics and guides you read today are not written in black and white. You should learn how to balance what you read by sticking to what the pro lifters are reading and using in their workouts. Also, you should remember that although there’s a lot of science in bodybuilding, most of it is still an art because it’s not always black and white.
Protein provides the amino acids used to build muscle. Shoot for 1–1.5g of protein per pound of body weight, or 180–270g a day for a 180-pounder. Top protein picks include dairy, eggs, poultry, red meat, and seafood. These foods offer a wealth of complete protein, providing your muscles with the aminos necessary for recovery and growth. You may supplement with whey, casein, and soy protein powders as well. And don’t overlook plant-based protein sources such as quinoa, beans, and hemp seeds.

When lifting it is essential to focus your mind completely on the muscle group you are attempting to work on. This makes sure that you are actually using the target muscle to lift the weight rather than accessory muscles or even momentum. This skill will develop with time, and as you progress in making that mind to muscle connection, your workouts will become much more productive and efficient.
