Working out After Male Breast Reduction Surgery

There is probably no absolute consensus on this topic.  I prescribe patients avoid heavy or repetitive pectoralis muscle exercises until I am sure there is no problem with seromas, drains are removed and most of the swelling from surgery is resolved.   This varies from patient to patient, typically 2-3 weeks for minor gynecomastia reductions and up to 6-8 weeks for larger procedures.  

After male breast reduction or gynecomastia surgery, the
chest needs time to heal and for the tissues to fuse back together. As a
result, I usually recommend four weeks of no exercise, two more weeks after that of
light lower body non-impact exercise and then easing back into regular exercise
starting at six weeks. I would not pursue excessive chest exercise for the
first six weeks after surgery and after that time, I would ease into the
exercises slowly and carefully ensuring the chest is not particularly sore as
long as you are cautious, use your body as a guide and take care during that
first 4-6 week period not to injure the surgical sites.
