Gaining muscle weight is not as difficult as some people want to see, in fact, is rather more simple than many believe. (Similarly see: Avi Mandel Jerusalem). I sincerely believe that overcoming the genetic differences that exist between us and the natural ability of each one to build muscle., There are some basic rules apply to everyone. There is no doubt that those who ignore the importance of these rules fail in their conquest to get the proportions muscle they want. Common errors when trying to gain mass: Work with the exercises wrong isolation exercises only work the small muscle origins and insertions. These exercises will give way to the muscle only, ie, will give shape to what you do not have, incongruous not?. You should use compound exercises, Basic and Heavy are those who build the Bell Muscular or Central Zone. Typically Feed Most do not understand the importance of nutrition when it comes to gaining weight, in fact have no idea what they should eat or terms and believe that the solution to your problem is to ask for a better workout routine, when in the bottom of the solution lies in the way of eating, ignorance in this respect is unbelievable. If you were to examine their diets usually do not eat more than 50 grams of protein and 2000 calories a day, and also include processed and packaged foods. Unfortunately those who are concerned about calorie intake does not tell the difference between those from pizzas, burgers, sausages and candy than they can be obtained from foods such as egg whites, chicken breasts or turkey, tuna , oatmeal, rice or a good steak without fat.
