Study Arms:
- Prehabilitation (Type: EXPERIMENTAL): The patients will undergo an exercise test on a cycle ergometer (VO2 max), a grip strength test (Jamar dynamometer), a Time Up and Go (TUG) test and a 6 Minutes Walking Test (6-MWT), before and after prehabilitation. Intervention involves 3 training sessions per week during 3 weeks preoperatively, according to the high intensity interval training model, wich consists of:~* 5 minute warm-up (50% of Cardiopulmonary exercise testing, CPET)~* Two 10 minute series of 15 sec sprint intervals (100%) interspersed by 15 sec pauses and a 4 min rest between the two series~* Cool down with a 5 min active recovery period (30%) The grip strength test (Jamar dynamometer), TUG-test and 6-MWT will be repeated between 4 and 6 weeks and 8 and 10 week postoperatively.
- Controls (Type: NO_INTERVENTION): The patients will also undergo an exercise test on a cycle ergometer, a grip strength test (Jamar dynamometer), a TUG-test and a 6-MWT, but only once preoperatively, and between 4 and 6 weeks and 8 and 10 week postoperatively.

Based on this trial design, predict the completion outcome and termination type (if applicable).
