Difficult clients being those clients who don’t enjoy physical activity. Suggested exercises should be able to be performed in a gym setting with common equipment (medicine balls, body bars, dumbbells, kettlebells, stability balls, free weights, smith machine, and the like). Suggested exercises should also be engaging and aimed at helping clients to see working out as an enjoyable and positive experience.
I would do some deeper client interviewing. What does the client want to be able to do in their daily life?
They may never see the gym as “fun” or an exercise as “fun.” But they may be sold on program adherence if you can connect it to a deeper desire for a specific lifestyle activity. For one of my clients, it was the embarrassment of not being able to get out of a kayak and being lifted out by her son and husband. Every time we did triceps dips, we knew they were her “kayak muscles.”
