Exercise after breast augmentation like cardio or chest exercises is something you should care about and need to know about.For the early period of recovery, that means two - three weeks post op, light exercise like walking outdoors is the best. I usually permit moderate exercise, if done with big caution after 4 weeks. Heavy exercise should be completely avoided for 8 weeks following a breast augmentation. I ask my patients to postpone all phisical activities at least until the pain and inflammation from surgery are fully resolved.Even after two months post op it is best to focus on lower body workouts. Any exercise that focuses on the chest, rotates the chest, or involves in working the pectorial muscles, as push-ups and weight training, should be avoided for at least 8 weeks, as they can significantly interfire with healing.I hope this helps, best of luck!
