When I started as a personal trainer, my club had a system where we gave each new member two “free” sessions. On the first session, we took them through a traditional exercise routine with the “boring blue card” where we marched them from one machine to the next, wrote down the seat adjustment, weight and suggested sets and reps.
Then, on our second session - which we called the “wow” session - we used non-traditional equipment, applied more “functional training” movements, and tried to impress the member with all the cool exercise combinations we knew.
