You can start by checking out Facebook groups and subreddits just to see who’s using platforms and see if anything stands out. Try cold-calling trainers in the area, tell them you’re doing research and ask them about their experiences, struggles, and successes. If you can, go hang out where other trainers are working and observe them. Take notes and see if any patterns emerge. Also try looking for influencers on YouTube or TikTok and see who’s getting the most views and engagement then try to figure out why.
