Fat, including the much-maligned saturated fat, is necessary for building a rock-solid physique. It revs up testosterone production, provides necessary calories, and helps your joints endure the heavy lifting needed to spur muscle gains. Aim for at least 0.5g of fat per pound of body weight (90g for a 180-pound man), or 30% of your total daily calories. Divide that into equal thirds from saturated fats found in beef, coconut products, and dairy; monounsaturated fats from almonds, avocado, olive oil, and peanut butter; and fat-burning polyunsaturated fats found in fatty fish, flaxseeds, hemp seeds, and walnuts. Avoid the trans-fatty acids found in fried foods.
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.
