These are some muscle building weight training tips

1. Don't follow other people's routines. You do not know how their bodies work, what they take (supplements/ anabolic steroids), how much sleep they get or whether they are telling the truth about their training!
2. If you are a bodybuilding beginner, stick to the basic movements and do not worry about isolation exercises. You can not define a muscle that does not exist!
   Go with the Squat, Bench Press, Shoulder Press, Chins/Bent-Over Rows, Dead-lift and Barbell Curls. Later on, after you have developed some good muscle mass, you can concentrate on more isolation movements.
3. Train at most 3 times a week and no more than an hour at a time.
4. Studies have shown that Testosterone levels start to decline after about 45 minutes of exercising. So if you are training for longer than an hour, then anything you do will probably begin to be counter-productive.
5. Keep the reps in between 6-12.
6. Do NOT over-train! Keep it intense and try to "work the muscle", rather than just "lift the weights"! Get a pump and feel your muscles doing the work.
7. Big muscles take longer to recover than smaller ones.
8. Fast twitch muscles take longer to recover than slow twitch.
9. Male bodybuilders recover faster than female bodybuilders.
10. You recover faster from slow movements than from fast movements.
11. You recover faster from low intensity training than from high intensity training.
12. Young bodybuilders recover faster than older folks.
13. Recovery is speeded up considerably by eliminating (or reducing) the "negative" or "eccentric" portion of the lifting movement.
14. Sound nutrition and ample rest allow for more rapid recovery.

Three main factors are required to promote muscle growth:

• Eat breakfast Proven time and again, those who eat breakfast are more successful at controlling their weight than those that don't. Plus, when doing strength training exercises (and you know you should be), it's even more important to make certain you fuel those muscles after an overnight fast. The perfect time for burning fat because glycogen, blood glucose and insulin levels are all low. Unfortunately, it may also be perfect for burning muscle, because glycogen levels are low, and levels of the catabolic stress hormone cortisol are high. If you skip breakfast and eat lunch at noon, you are not only in a highly catabolic (muscle wasting) state, you are also sending an unmistakable starvation signal to your body.
  
• Eat less sugar Start reading labels! Sugar is hidden in almost every commercial food item. A single tablespoon of ketchup gets 3 of its 4 grams of carbs from sugar. A 12 oz can of cola has a staggering 40 grams of sugar, and ALL of the carbs in a cola are sugar! Why does that matter? Simple sugars are digested very quickly and cause a rapid spike in blood sugar. Your body then releases large amounts of insulin. Insulin quickly clears the glucose from the bloodstream leading to low blood sugar (hypoglycemia.) Low blood sugar causes cravings, hunger, weakness, mood swings and decreased energy. These cravings for sugar result in a vicious cycle of ups and downs in blood sugar levels throughout the day.
  
• Eat More Often Studies have shown that those who eat 4-6 smaller meals per day have less body fat than those eating 2-3 meals a day, even if both groups eat about the same number of calories. This is because of maintaining steady blood sugar levels. Too much insulin activates fat storage enzymes and forces fat in the bloodstream into fat cells for storage. High insulin levels also inhibit enzymes that promote the breakdown of existing stored body fat. You can manage your blood sugar and insulin levels by choosing fewer simple carbohydrates, more complex carbohydrates, eating fiber and having your carbohydrates with lean proteins approximately every three hours.
  
• Eat protein Be sure to include enough protein for your level of activity (you are exercising. Right?) Protein speeds up your metabolism because your body has to work harder to digest, process, and utilize it compared to fats or carbs. The "thermic" effect of protein is one of the reasons that a higher protein diet is more effective for fat loss than a diet high in fat or carbs. Too much of any food can be stored as body fat, but protein is less likely to be converted to fat than any other nutrient.
  
• Eat nothing from a box The closer your food is to nature the better off you are. Have you looked at the ingredients list in most packaged food these days? You need to be a scientist to figure out what half the ingredients are. Stick to real, wholesome foods, fruits, vegetables, whole grains, lean protein, etc. Eat your vegetables I don't mean fast food french fries. Try to get as many vegetable servings into your meals as you can. It's nearly impossible to over eat vegetables. They are full of fiber and will help keep you full between meals. They also contain loads of antioxidants. Raw is great, steamed is another good way to have them. Hold the heavy cheese sauces please!
  
• Eat protein and carbs together If you want to keep your blood sugar in check, then don't eat your carbs by themselves. Strive to always have balanced meals of protein, carbs and healthy fats. You'll feel better and your muscles will thank you.
  
• Prepare your own food Best for several reasons…It's cheaper than eating out, you know exactly what you are eating, and it saves time. It takes no more time to cook up 6 healthy chicken breasts than it does to cook one or two. Make things easy. Prepare them over the weekend and your lunches for the next few days are done. While you are at it, put on a pot of brown or wild rice, or bake up some sweet potatoes and you're good to go.
  
• Drink water LOTS! Most people are already dehydrated. Strive to drink a gallon a day. If you drink a lot of coffee, then you need an extra 8 oz for each cup of coffee. Exercise will put more demands on your fluid levels. You need water. Drink 50-75% of your body weight in ounces of water. Add an additional 16 oz for strenuous exercise. No complaining!
  
• Get more exercise Get some exercise on most days of the week, and alternate between strength training exercises and cardio training. If you are a beginner, shoot for two weight workouts a week and progress to 3 or more depending upon your goals. Get in as many cardio sessions as your schedule will allow, but aim for at least 3. Commit to adopting these nutrition program changes and you'll be well on your way to reaching your weight loss goal, whether it's ten pounds or many more. Sound nutrition and exercise will always succeed in the long run. Don't give into the temptation of fads.
