When I first began training with clients, I knew rapport was important, but I did not realize how essential it was to keep clients coming back. There must be some kind of common ground, understanding of one another, or trust that you as the trainer, have their best intentions in mind. A client must view you as someone they can go to for not just exercise and nutrition advice, but also life advice. A client who feels disconnected from you, will not be able to fully commit to training with you because they may not be fully convinced you want to see them succeed or help them towards success.
