Resting blood samples will be collected at the Clinical Translational Science Institute (CTSI) facility by a trained phlebotomist and total GSH and redox status analyzed by a co-investigator. Biomechanical assessment and survey data will be collected in the Konczak laboratory by a trained graduate research assistant. All data will be collected at baseline and 12 weeks from both treatment and wait-list control groups. The 12 weeks data from the wait-list participants will serve as their second baseline before they began the intervention program. Their post intervention data will be collected at 24 weeks post randomization to increase power.
