In the magazine there's a picture of him doing weighted dips, so there's some proof that he kept up with some form of regular lifting...it just might not have been what the Saints' strength coach recommended.
I thought it was a good article, though. The workout definitely looks like it has some sport-specific carryover but like anything else, it's not the end-all, be-all of exercise.
I could do that workout and it still wouldn't make me the athlete Reggie Bush is. You can't train God-given abilities, but you can make those abilites better through training.
Being different is in these days, especially in the fitness world. You take an existing idea, but your creative spin on it, market it as an orignial idea, get some celebrity and/or athlete to back it and boom, you've got yourself a thriving business.
