The absolute number one most important factor to building muscle is to have the correct bodybuilding diet plan.
It does not matter if you are now a 98 pounder just starting out, or an experienced, ripped expert - your diet contributes is at least 60% to your success or failure when building a lean body.
You may think you understand nutrition the way you should, and you may think that a bodybuilding diet plan should be radically different that a plan that a normal person would use- nothing could be further from the truth.
Good nutrition is good nutrition, no matter what your level of physical activity.
Don't fall into the trap that many who are working at building muscle fall into - you need a balanced diet and slow, steady progress regardless if you are working at building muscle or not.
Over use of supplements can be hard on your kidneys and liver - also be careful about your protein intake as a percentage of your total calories.
You need carbs, protein and fats in the right balance to build healthy muscle tissue.
The right bodybuilding diet plan is really the same as any good diet plan - balanced, safe and focused on long-term, steady progress.
Follow this common-sense advice and you'll see the ultimate results you are looking for.
