I have one male client who I train at his home. He has Parkinson’s and can not longer come to my studio because the process of getting here is just to much for him.
But I know that that is not the scenario you had in mind when asking this question. I would think twice before training a man at his home unless I know his family (wife), or under circumstances as described above.
It is not so much that I am afraid of an assault but than finding myself in a situation that may invite ‘misunderstandings’. In personal training, it can get close, and it is better to be in an enviroment that does not suggest anything but exercise.
