Study design: The investigators will use a pre-post pilot study design. The assessments will be held at either the Dartmouth-Hitchcock Medical Center (One Medical Center Drive, Lebanon NH 03756), or The Dartmouth Centers for Health and Aging (46 Centerra Parkway, Lebanon, NH 03766). Assessments will be conducted by the principal investigator (PI), and/or a research assistant (RA). Consent and approval of the Committee for the Protections of Human Subjects of Dartmouth College will be obtained prior to starting the study. Volunteer non-exercising and under-exercising participants aged 50-85 will be recruited through flyers and provider referral. Recruitment will continue until 10 participants answer "yes" to the exercise question on PDx. Written informed consent will be obtained for all participants.
