People with training ADD typically understand what goal they have in mind initially but for what ever reason become unhappy with their situation and decide to change midway through. Since making changes in body composition and performance are relatively slow processes people with Training ADD never reach the level they set out for.
A common example of this is a trainee who decides they want to gain muscle. After researching the best program and diet to gain weight they set out on an effort to become huge. They realize after two months of bulking up that they are starting to lose definition in their abs. Regardless of the fact that the rest of their body is growing well and their strength is through the roof they panic and decide that they need to cut back, and make a 180 degree shift dropping calories and focusing more on cardio. After a few weeks of this they are back to square one because they didn't put on any appreciable muscle mass, and the muscle they did put on was lost in their reactive effort to cut back down in a short time. And this leaves the trainee exactly at square one.
Training A.D.D. does not just have to be applied to body composition changes but we can also see this in performance measurements when a person tries to train for to many different things at once. They want to be good at long distance running, and powerlifting, all while being fast. Their training tries to resemble this by switching between mutually exclusive goals all at once. And in the end they get no where because they don't pick with one goal and focus on it!
People with great physiques or great speed or great power all or all of the above have gotten that way over a long period of time. Whatever their goal was they stuck with tried and true methods and were CONSISTENT! This does not mean consistency for a month or two. Consistency means dedicating yourself to a diet and fitness regimen for years.
So far all those with training ADD set a goal and stick with it for at least three months before re evaluating.
