I think that your are referring more towards supplement sales rather that the bodybuilding competion. The expo is all about supplements. And Jon Jones has the longest line at the Arnold/Olympia expo.
let's see here...
1. there's no shortage of money when it comes to bodybuilding. if there were they wouldnt be paying an all time high of us 400 000 dollars to phil heath.
2. there's no shortage of people wanting to see phil heath and the rest compete - otherwise there wouldnt be that kinda prize money.
3. there's more people than ever attending the show and the expo.
4. there's a bigger expo and more booths than ever.
5. there's a bigger general interest for muscle and bodybuilding than ever before, as proven by millions upon millions who follow the bodybuilders on social media, dorian yates coming onto one of the biggest podcasts in the world, documentaries etc, kai greene and others breaking new ground in india and other countries.
if youre denying that bodybuilding is at an all time high, you belong to the earth is flat-camp.
