What they did
Once interviews give a medium-confidence pattern (e.g. non-converters couldn't find a workout format or exercise), form a hypothesis and test it as cheaply as possible: an automated survey after the first three workouts ('How did your three workouts go? Was there an exercise or format you couldn't find?'), or better, an intervention on the one or two surfaces where users would look, asking 'Could you not find this, yes or no?' to size the problem before building.
