Data collected from patients' calendar records of REST adherence and steps per day will be described in terms of proportions and means, respectively. An arbitrary threshold of 75% will be used to distinguish participants who did and did not adhere to the recommended 4 sessions per week. Participants who did not perform their REST program 4 times per week for at least 6 of the 8 weeks during the training phase will be considered non-adherent. Exploratory analyses of significant differences between participants that did and did not adhere will be performed with nonparametric testing.
