Your plastic surgeon will be your best resource when it comes to returning to your specific line of work. He/she will know how you are progressing and whether or not you have experienced any complications. Generally, most patients are able to return to a “desk job” within 5 to 7 days. More strenuous work, for example involving lifting or extensive upper body movement, will require more time off. In my practice, most personal trainers are able to return to work one week after breast augmentation surgery, assuming that they are mainly supervising, not demonstrating the planned work out etc. I ask patients to avoid heavy lifting for 4 to 6 weeks after surgery and avoid pectoralis major specific exercise (push-ups, bench press, flies…) for several months. I hope this helps.Best wishes.
