Adherence

Prescribed moderate-intensity exercise does not increase the risk of injury or illness in overweight and obese adults compared to sedentary controls; injury risk is driven by BMI, not exercise volume.

If you are overweight or obese, starting a moderate walking program (150-300 minutes/week) will not increase your risk of injury compared to staying sedentary. Your body weight (BMI) is a stronger predictor of injury than the exercise itself. Focus on gradual progression and weight loss to reduce injury risk.

GoodRefutesHIGH confidence
Overweight and obese adults who were prescribed exercise as part of weight loss or weight gain prevention intervention were not at increased risk of injury compared to overweight adults randomized not to participate in prescribed exercise.
