Online fitness coach? Yay or nay?

[Namesnamesnames13]

Curious, would anyone have an online fitness coach? It seems a bit market these days, but who actually does it?

I have a male friend that is a pt on line coach.

I dont know how much he charges but he seems to succeed at it and isn't changing his career any time soon He specialises in Triathlon training and writes individual nutrition, lifestyle and training plans and monitors progress by highlighting and working on weaknesses in technique and stamina.
He is a Triathlon as competes in Ironmans so has expierence as well as being knowledgeable. Some of his clients have been with him a long time so he must be doing something right.
He us at full capacity and has a waiting list which i didn't realise until recently was a thing!
