  The work presented in this paper aims to explore how, and to what extent, an
adaptive robotic coach has the potential to provide extra motivation to adhere
to long-term rehabilitation and help fill the coaching gap which occurs during
repetitive solo practice in high performance sport. Adapting the behavior of a
social robot to a specific user, using reinforcement learning (RL), could be a
way of increasing adherence to an exercise routine in both domains. The
requirements gathering phase is underway and is presented in this paper along
with the rationale of using RL in this context.
