Genetics are a powerful factor in the success or failure of a bodybuilder. That fact is undeniable. But to a degree, less than ideal genetics can be overcome via hard work, perseverance and having the correct information on effective strategies for training, nutrition and muscle building supplementation. Again, if you're a heavyweight with 14-inch arms, hard work probably still won't be enough to make you a star. Seeing many genetic specimens who don't want to work as hard as others do, or who won't do so without the constant presence of a "babysitter". In short, they are lazy.
THE LAZY BODYBUILDER: Lazy could include such behavior as not doing scheduled cardio sessions, or not doing them at the intensity level prescribed. It could be skipping meals, cheating on your diet, failing to prepare your meals or substituting inferior food sources for better quality foods, either for the sake of cost or convenience. There is a world of difference between the nutritional value of a grilled chicken breast you cooked yourself versus a one-piece box of McNuggets---but the lazy bodybuilder would rater hit the drive-thru than take the time to cook.

In the gym, the lazy bodybuilder will use mostly machines and just a few favorite free weight exercises (most likely benches and curls), while avoiding the toughest and most productive movements like muscle enhancer squats, deadlifts and barbell rows. He may skip leg day to do an easier, more fun body part like arms. Before, during and after the workout, the lazy bodybuilder may drink a supplement loaded with sugar that they have been instructed to avoid, because they got it cheaper or for free. Basically, all of this comes down to a lack of detail, lack of planning and avoidance of effort.
The worst part is that a person like this will often hire a trainer or nutritionist and expect them to pull some magic fairy dust out to make them look phenomenal over the course of the last week leading up to the contest. It simply doesn't work that way. A truly great physique on the day of the contest is the end result of many great mass gainer workouts, great bodybuilding meals and weight lifting supplements and astute attention to detail. Genetic factors aside, these "little things" add up and can often make the difference between first and 10th place.
