In this study a personalized, multi modal prehabilitation intervention will be offered to n = 64 patients on the kidney transplant waiting-list. The control group (n = 64) will receive care as usual. Based on a screening, comprised of questionnaires and physical test, eligible kidney transplant candidates who have modifiable problems on the domains of physical capacity, nutritional status or psychological well-being, will be randomly assigned to either the intervention or control group. The intervention will consist of a 12-week prehabilitation program followed by a 12 week consolidation program. Primary outcome will be frailty status as an indicator of overall health status and will be measured at screening (T0), 13 weeks (T1) and 26 weeks (T2)
