Kidney Transplant Donor

The goal of this clinical trial is to learn if a pre-operative outpatient exercise programme, monitored by a smart wearable device is acceptable to live kidney donor and recipient transplant patients. It will also look at the impact of prehabilitation on post operative outcomes. The main questions it aims to answer are: Is it feasible for renal transplant patients and live kidney donors to participate in a prehabilitation programme in combination with a piece of wearable technology? Are transplant outcomes improved by prehabilitation regimens delivered by video instruction? Are there discernible perioperative digital signatures provided by the wearable that link to surgical outcomes? Is the quality of perioperative sleep linked to surgical outcomes? Participants will: Wear a wrist or ring worn wearable device for a total of 14 weeks (2 week baseline, 6 week pre op and 6 week post op) Engage in a 6 week pre operative exercise programme at home/gym Keep a diary and answer surveys on their experience of the exercise regimen and wearable device
