For the most part no it's not. It's just that most people are too stupid notice that when they Google / yt something they're supporting / subscribing to bs. You wouldn't get your news from the first website / channel that pops up if it was from infowars, prison planet or Fox news. It's the.same, with fitness as legitimacy goes. I've been reading exercise science from legit sources for.years.That's nutrition and exercise in general.
