I have a 50(ish)k followers on IG and used to do bikini fitness competition and got an IFBB pro card - a relatively okay supplement company sends me stuff monthly and pays me a minimum amount of money. Also run posing classes, which I charge for.
Whilst not strictly money I also get sent meat hampers monthly from a fairly well known hamper company and gym clothes every couple of months from another.
I have at anyone times 4 clients that make training plans for as well as diets - these go down to macros. Could do more but would take up alot of my spare time.
I have designs on red bubble, zazzle, society6, and cafe press which sell a small amount each month with no effort from my self.
I am signed up to a few sites like upwork where I do freelancing work, but am generally to lazy to compete for jobs on there. Last couple of years also unfortunately they have now become an open markets and people from countries that have a way lower cost of living can also bid to do the work for a much lower cost than I'd think reasonable.
I have a blog which gets semi okay readers and have affiliate links on there, so earn per click through.
If I was more proactive I could earn more,
