Hypothesis: The PP exercises will be feasible (i.e., 4 of the 7 PP exercises will be completed by a majority of participants, and participants will have a mean score of at least 7 out of 10 on ratings of ease of completion for the exercises. The PP exercises will also have adequate immediate impact (i.e., mean ratings of 7/10 of exercise utility post-exercise and ratings of optimism post-exercise that are significantly higher than pre-exercise).
