for the first photo i can see he sets up his offer as a physiologst who helps athletes reach high performance after injury or just recovering. he promises results like athletes returning to sports after ACL injuries and he posts reels showing IRL clients training etc. I can see he communicates thru posts and his linktree which leads to how to book and appointment with him online.
For my 2nd coach i found Coash Keren she seems to be a mental health or life coach she offers a coaching programe that offers peace and clarity. She seems to communicate through posting as well and she has link to her website as well as books in her bio
for my last one she is another fitness coach, she offers online sports coaching that helps people loose weight and overall become fitter, they all seem to promise the same result in the fitness industry, and all three of these coaches communicate thru reels, DMS and links leading to websites in their Bios
