Fitness industry summed up:
1. Jump on juice
2. start an insta, tiktok, youtube
3. generate views/base
4. copy some diet books and sell meal plans to people
5. sell workout plans
6. sponsors will start approaching and you have finally made it
Also, most importantly, claim natural and pretend you don't even know what steroids are, else those sponsors won't approach.

And if you want to ramp it to peak scummy levels, get into the supplement industry and start selling your own bunk supplements with poor quality control.
