Strategy (Behavior change technique)	Example
Goal setting	Agree on attending 2 sessions of exercise therapy/weekly with the person and reach agreement about the goal
Behavioural contract	Sign a contract with the person e.g., specifying that they will attend the exercise therapy sessions as planned
Self-monitoring of behaviour	Give patient a pedometer and a form for recording daily total number of steps
Unspecified social support	Advise the person to call a ‘buddy’ when they do not feel to have the motivation to attend the exercise therapy sessions
Non-specific reward	A reward was given to the patient if PA goals were met
