I have two clients who would be considered ‘morbidly obese’. I have worked with them now for a good number of years.
The number one issue for me was psychological, not physical: making a client feel comfortable and accepted and developing mutual trust. I try to instill a respect for their own bodies who – rightly oor wrongly – they have come to despise.
Fortunately, I have my own studio which I only share with my husband who is also a trainer. More often then not, I am alone with my client. This degree of privacy has helped tremendously because there are awkward situations at times when it is difficult for the client to move in certain ways or even try something new.
