LL Cool J works with a trainer very extensively, he also has chicken legs.
I think the excuse to not count your calories is an excuse. And I doubt that working out 3 times a day is necessary to achieve results except in extreme situations (heavy dieting/cardio).
I laughed when I heard that trainer tell Usher that, he's an idiot, but he got results. Better than a smart guy who gets none.
Some of the celeb trainers have good advice, my nutrition plan I basically took directly from an interview in Self: 5 x 500-700 calories, increase or decrease in increments of 50-100 per meal.
The problem is some of their advice is terrible. Since there is no advisory board shutting down the crappy stuff, they also end up disseminating worthless info e.g., balancing stuff.
