For many of us, being fit offers a personal high which is borderline spiritual. Being thankful for your body and its ability to perform is also spiritual. Do you ever engage in the spirit of fitness with your clients in addition to the technique? What do they think of it? (not so much a question for yoga or similar practices. more generalized fitness).
I only go as far as a mind/body connection. Yes, there have been times when a client – despondent for whatever reason – needed more of a shoulder to lean on than a dumbbell to lift. I may then go the ‘we have so much to be thankful for’ route, if applicable, but I certainly avoid any religious over- or undertones.
