Typically 1 week after #gynecomastia surgery you can begin taking moderate walks or ride a stationary bike. Strenuous #workouts or aerobic #exercise can begin around 4 weeks post-op. Please get approval from your doctor before you begin any workout regimen.
I have my patients wait 4 to 6 weeks before doing any exercise, try to be patient, you do not want to set your recovery back. You should check with your surgeon on this. Good luck.
My patients are instructed to refrain from upper body workouts for at least a full 4 weeks after gyno surgery
In my opinion I would not exercise your shoulder because that can activate your chest muscle and the chance for increased pain or fluid collections. I would seek counsel from your plastic surgeon.
