Environment often dictates the quality of a workout. A mix of familiarity, anticipation, and the right community (lifting partners/demographic/coaches) can create an overall feeling of eustress (as opposed to distress) respective to the session. This often impacts your experience much more than your program design and available equipment selection, and these are things that everyone recognizes (often subconsciously) and inherently appreciates.
This is service, creating an environment that drives engagement and perpetuates adherence. THIS is what creates a platform for your message to be heard.
As a trainer you should be trying to recreate those variables respective to each clients needs.
Ask yourself, how do you set the environment to create eustress rather than distress?
How do you communicate with them?
Do you care?
Would you train with you?
