Prehabilitation is a strategy to increase reserve in anticipation of an upcoming stressor. Patients with poor baseline functional capacity are at increased risk of complications and prolonged recovery (1,2). Emerging evidence suggests that a 4-week period of prehabilitation can increase walking capacity in colorectal cancer patients, and deconditioned patients in general make the biggest gains. However, no impact on complications has been seen in the available small studies. Exercise programs should include aerobic and resistance exercise and should not be too intense. Patients start with minimum 30 minutes of aerobic activity (walking/biking) 3 times per week at moderate intensity, with the pace gradually increased over time. Optimization of nutrition and stress management strategy improves the effect of the exercise intervention (3,4). Patients who begin the exercise program preoperatively tend to continue exercising postoperatively, making it an attractive strategy to support functional recovery (3).
