as trainers, we have to respect the goals of the client as long as they are not detrimental to their health. It sounds to me that this client recognizes the value of exercise but also the fact that he or she will not do it unless somebody stands over her. In her view, she is meeting her goal by doing just that.
But that does not mean that you have to do the same things over and over. You can progress her even without her knowledge. There are many variables you can throw into the mix to keep a workout interesting and engaging. Adding balance challenges for example as you keep the resistance the same is a progression.
I am sure that this can be the beginning of a beautiful relationship 🙂
