It is generally safe to resume light walking immediately following breast augmentation surgery. Short walks are recommended as walking helps to prevent blood clots post-surgery. However, any heavy, strenuous exercise should be avoided for four to six weeks until your doctor gives you the green light. Following aftercare instructions is important to have a smooth recovery and ensure optimal results. On average, patients are fully healed and can resume all forms of exercise, including cardio, within six weeks of breast augmentation. Breast implants should not prevent you from having an active lifestyle. There is no need to stop running, lifting weights, or other forms of exercise after a breast augmentation.
