Just visit the classifieds section:

http://www.warriorforum.com/warrior-...lassified-ads/

Of course it`s possible and it`s the best idea to get it from known warriors

Just do a search for the forum. Enter solo ad or solo ad + fitness. That will narrow the search down for you.

Good question, I am looking for Solo ads myself in some niches I cannot find, like acne cure niche.

Safe-swaps have a lot of good solo ads but they have a category of health however I want it to be more targeted.
