RECRUITMENT: This study will be conducted at Mayo Clinic in Rochester, MN. Patients over 18 who were approved for kidney transplant and identified as frail or pre-frail during their kidney transplant evaluation will be approached for recruitment. Interested patients will go through the informed consent process and, if frailty testing was not completed within the two weeks prior to consent, patients will complete frailty testing. If patients are considered frail or pre-frail, they will be enrolled in the study.
FRAILTY TESTING: Participants will complete the Short Physical Performance Battery (SPPB) and other frailty testing at the beginning of the study, 4 weeks after beginning the intervention, and 8 weeks after beginning the intervention. Frailty testing will include a hand grip strength test, a gait speed test over 15 feet, repeated chair stands, balance testing, and a body composition scan. Participants will also be asked to wear an activity monitor for 5-7 days at each testing point and to complete a set of questionnaires.
INTERVENTION: Participants will be asked to complete 2 1-hour exercise sessions per week for 8 weeks (16 total sessions) under the supervision of a licensed respiratory therapist in Rochester, MN on non-dialysis days. The exercise sessions will be based on pulmonary rehabilitation and will follow guidelines established by the American Thoracic Society. Exercise sessions will include endurance, strength, and flexibility training and will be tailored to individual participants.

Experimental: Exercise Program
All participants will attend a 16-session exercise program based on pulmonary rehabilitation and will complete questionnaires and frailty testing.
Behavioral: Exercise Program
Participants will be asked to complete 2 1-hour exercise sessions per week for 8 weeks (16 total sessions) under the supervision of a licensed respiratory therapist on non-dialysis days. The exercise program will be based on pulmonary rehabilitation and will follow guidelines established by the American Thoracic Society. Exercise sessions will include endurance (treadmill or cycle ergometer), strength (weight resistance), and flexibility training. Exercise sessions will be tailored to individual participants, and participant safety will be monitored during each session.
- Change in Frailty Status [ Time Frame: 2 Months ]Frailty will be determined by Frailty Phenotype (FP) or Short Physical Performance Battery (SPPB) scores. FP is determined by the presence of 3 or more of the following: slowness (measured by gait speed), exhaustion (measured with the CES-D), weakness (measured by hand grip strength), low physical activity level (measured with the MLTPAQ and activity monitoring), and wasting (measured through self-report or by tracking changes in weight). The SPPB consists of a gait speed test, balance testing, and repeated chair stands. A score less than or equal to 10 will be considered frail.
- Change in Grip Strength [ Time Frame: 2 Months ]Hand grip strength will be measured using a hand-held dynamometer. Frailty is characterized as the lowest 20% by gender and body mass index.
- Change in Gait Speed [ Time Frame: 2 Months ]Gait speed will be measured over a distance of 15 feet at the patient's self-selected walking speed. Frailty is characterized as the slowest 20% by gender and height. Results will be prorated for 4 meters for the SPPB score.
- Change in Exhaustion [ Time Frame: 2 Months ]Patients will self-report their level of exhaustion using the Center for Epidemiologic Studies Depression Scale (CES-D) which consists of a 4-point scale. Items on the CES-D are scored from minimum to maximum values (1 point to 4 points) which are indicated on the CES-D as "rarely or none of the time," "some or a little of the time," "occasionally or a moderate amount of time," "most or all of the time," respectively. A higher number of points indicates a worse outcome.
- Change in Activity [ Time Frame: 2 Months ]Energy expenditure will be measured using an activity monitor worn on the wrist for 5-7 days. Low activity is defined as activity in the lowest 20% (<383 Kcals/week for men or <270 Kcals/week for women). Patients will also self-report their activity level using the MLTPAQ.
- Wasting [ Time Frame: 2 Months ]Wasting is defined as a decrease in lean body mass or unintentional weight loss of 10 or more pounds in one year.
- Change in SPPB Score [ Time Frame: 2 Months ]The SPPB consists of a gait speed test, repeated chair stands, and balance testing. Lower scores indicate decreased physical function.
- Change in Quality of Life [ Time Frame: 2 Months ]Health-related quality of life will be measured using the KDQOL-SF.
- Post-Transplant Outcomes [ Time Frame: 1 Year ]The relationship between exercise, frailty status, and post-transplant outcomes will be examined for patients who receive a transplant within 1 year of enrolling in this study. The various outcome measures will be aggregated to indicate mortality rate up to one year post-transplant.
