How to Break Up With Your Personal Trainer Be honest. Even if it might hurt to hear, personal trainers want to know why you're ending the relationship. A compliment or two can't hurt. As a customer, be in control.
Show a little respect for us as well. To make it as painless as possible, avoid playing the blame game. Just tell your coach that you don't think they're a good match. If they insist on knowing the reason, use decorum.
State the facts concisely and, if possible, give specific dates and a series of events. Don't let them pressure you to change your mind. Obviously you want to be a decent person who is respectful to your PT. And on top of that, if you annoy your PT, you'll end up feeling uncomfortable if you continue to attend the gym where he works.
So, in general, it's best to be mature and polite about it.
