Weekly engagement will be measured as the fraction of the following elements completed each week: exercise therapy-directed activities, daily entry of exercise data and rated perceived exertion (RPE); completed weekly phone call with exercise therapist; at least one communication with exercise therapist (outside weekly phone call); reviewing educational video/text (which will vary by week).

Competition will be assessed as a pseudo-continuous outcome, as the score can range from 0% (0 activities completed) to 100% (all activities completed) incorporating values for each activity.

Step count is measured on a continuous basis and data will be obtained from the wearable activity monitoring device.

The EQ-5D comprises five questions on mobility, self care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem). A summary index with a maximum score of 1 can be derived from these five dimensions by conversion with a table of scores. The maximum score of 1 indicates the best health state, by contrast with the scores of individual questions, where higher scores indicate more severe or frequent problems.
