Intervention Overview. The intervention is provision of an individualized, 2-part, 3-tiered REST program which will include the exercises listed in Table 1 to all participants randomly assigned to the intervention arm. In addition, participants will receive a step pedometer and will be encouraged to remain as active as possible during the study period based on objective feedback from their pedometer readings. A PT specialized in cancer rehabilitation will instruct participants in REST and will adapt the program to accommodate for symptoms, co-morbidities, or other issues that may impede a participant's ability to perform the REST program. The PT will follow up with each participant by telephone at 1- and 2-weeks following REST instruction to encourage participants and to problem solve regarding any barriers which may be impeding their performance of REST. After the 2-week initiation phase, participants will perform REST independently during an 8 week training phase but will be encouraged to contact the PT with any questions or difficulty. Patient reported outcome (PROs) measures will be collected at baseline prior to REST instruction and after completion of the 2-month training phase, as outlined below.
