Sometimes suggesting to these potential clients “can I show you something different?” can trigger their curiosity and if they like what they see, they will sign up. If you are offering training as anyone else around, then they will be more resistant in buying sessions. You asked this question a few days back and my answer is still the same: there are many interpretations of the term “fit”. You will need to define what “fit” means to you and then try to sell it to potential clients. I hope this helps.
