Themes identified from written feedback
Enjoyable & worthwhile	Overall, participants experienced the programme as something that was very worthwhile. They considered there to be many benefits to engaging in the programme allowing them to experience further secondary benefits (e.g., reduction in pain, increase in mental health/well-being) which made the programme even more worthwhile. Generally, participants perceived the activities in the programme as enjoyable.
Practicalchallenges to engage with the programme	Practical challenges were experienced by participants which prevented them from engaging with the programme. This included challenges such as fitting the exercises around their daily tasks/schedules, and considering how to continue the programme when going on holiday and/or not being near a technical device.
Frustrations due to technical issues & capabilities	While the participants recognised the excellent support the team provided, they experienced technical difficulties which they mentioned were particularly frustrating. Furthermore, participants identified frustration when they were unable to use certain technical capabilities they might have expected (e.g., being able to skip the instructions of videos).
Concerns and challenges to perform the exercises	Overall, participants identified that certain physical health problems could prevent them from engaging in the programme. (e.g., illness such as flu, injuries, feeling exhausted, other health difficulties). They also identified that they were particularly concerned about performing exercises when experiencing physical issues or injuries (although the similarity of the exercises to NHS and physiotherapeutic exercises managed to reassure most people).
Timing of the programme	While most participants mentioned that they experienced a benefit from engaging in the programme, some participants were concerned about the benefit – particularly when the programme did not align with their surgery date. Furthermore, participants were concerned about losing out on the benefit when stopping the programme (e.g., due to still not having a date for their surgery when the programme had finished).
