Every major celebrity in the fitness bubble is hiding a secret from the entire world and it's taken YouTube gamer PewDiePie to expose it. The Swedish superstar made an uncharacteristic video on the lack of transparency of steroid use in the movie industry, specifically calling out actors who have gained impossible amounts of muscle to play superheroes in the Marvel cinematic universe.

On episode 110 of Just The Fitness Tip we ask, is the fitness industry lying to you about how celebrities achieve ungodly physiques and if so, is it immoral for them to profit from products or services they claim to provide results without that transparency?

Chris Hemsworth sells his Centr app, inferring it is how he manage to pack on 40lbs of muscle in under a year.

Kumail Nanjiani transformed his physique aged 40, apparently with nothing more than beetroot juice and electric shocks to his muscles.

Dwayne "The Rock" Johnson has a lucrative partnership with Under Armour and a highly profitable energy drink based on his philosophy of "blood, sweat and respect" but is it really just tenacity and 3am workouts that resulted in the musclebound 50 year olds unbelievable gains?

Most importantly, PewDiePie has the largest YouTube audience in the world, largely made up of young boys who may know little about fitness but certainly know of these celebrities. We talk about the responsibility the media has not to spoon feed beginners with misinformation that could potentially result in long term damage, both physically and psychologically.
