Iformsupport offers training program with online support included. I am a physiotherapist and I have made the programs and I do the online support as well. Here: https://iformsupport.dk/sadan-foregar-det/ it is explained briefly how it works.
I also write a lot of articles related to exercise and training equipment. I compare treadmills, exercise bikes, rowing machines etc. so the reader can get an idea of which one to buy (affiliate).
