Nope. There is very little money in true exercise. The profits come from unhealthy things such as protein supplements, harmful body building, gyms that promote unhealthy exercise routine, etc.

Protein powder is just protein - it's a specialized food source. Are there bad supplements? Totally - but dodgy salad will give you salmonella.

Bodybuilders actually use intermittent fasting - the unhealthy bits is the supplement abuse, but that's the sort of thing that happens with any extreme lifestyle. That's also a super limited view of the strength world.

What's an "unhealthy exercise routine"? Literally anything is better than doing nothing. Is it optimal? No, but if it gets you moving it helps. Are you talking injury or things that actively make you less "healthy"? I could see an argument from injury, but I'd rather someone have a ruptured ACL now than heart disease later.

I feel like we're about to enter "No True Scotsman" territory here.
