Purpose: In the first month following bariatric metabolic surgery, patients can expect approximately half of their weight loss to consist of lean body mass. In addressing this muscle loss, current guidelines encourage patients to maintain adequate protein intake but suggest that patients avoid or limit resistance training until recovering from surgery. This review aims to evaluate the level of evidence suggesting adverse outcomes associated with physical exercise in the immediate postoperative period following bariatric metabolic surgery. Methodology: We systematically searched the literature for evidence suggesting a relationship between postoperative complications and the level of exercise completed immediately following bariatric metabolic surgery. Results: Of the 39 included studies on postoperative exercise, none suggested postoperative exercise as a risk factor for complications following bariatric metabolic surgery. Conclusion: Following bariatric metabolic surgery, there may be substantial benefit to engaging in low-impact resistance training in addressing resultant sarcopenia. This review found no association between the level of postoperative exercise and the incidence of complications. Based on our analysis of the available literature, we suggest that low-impact resistance training is safe in the immediate postoperative period following bariatric metabolic surgery. Future clinical trials involving supervised low-impact resistance training will likely be safe and allow us to provide evidence-based recommendations on postoperative resistance training in this patient population.
