Summary Obesity and physical inactivity are major health problems. Roux‐en‐Y gastric bypass (RYGB) surgery results in significant weight loss and reduces obesity‐related morbidity and mortality. Physical activity lowers the risk of cardiovascular disease and premature death. The aims of this study were to elucidate the effects of RYGB followed by 6 months of supervised physical training on physical capacity. In a randomized controlled trial, 60 participants eligible for RYGB were randomized 6 months post‐surgery to either two weekly physical training sessions for 26 weeks (INT) or a control group (CON). Aerobic capacity (VO 2 max), muscle strength (MS) of the shoulder and hip and physical function were measured pre‐surgery and 6, 12 and 24 months post‐surgery. RYGB per se decreased MS in all tested muscle groups, had no effects on VO 2 max but improved physical function. After the intervention, INT had a significant 0.33 L min −1 increase in VO 2 max compared to CON (95% CI: 0.07–0.57, P = 0.013). Furthermore, MS in the hip adductor increased significantly with 13 N (95% CI: 3.6–22.4, P = 0.007) and a between‐group difference was found in the Stair Climb Test (0.46 repetitions [95% CI: 0.02–0.91, P = 0.042]). The effects were not maintained at follow‐up. Supervised physical training following RYGB improved VO 2 max, hip MS and physical function, but the positive effects were not maintained at follow‐up. While activities of daily life may become easier as a result of RYGB, the observed extensive post‐operative loss of MS requires more attention to increase the patient's physical capacity prospectively.
