Can Gynecomastia Be Corrected with Chest Exercises?

Gynecomastia will not go away with any chest or "pec" exercises.  Most patients that have "gynecomastia" have some "component" of fatty tissue as well as "glandular" gynecomastic tissue that causes the chest fullness.  Chest exercises and push-ups can reduce some of the fatty tissue to the chest (in general) and also help develop the pectoralis muscles of the chest which can add muscular shape and volume to the overall chest appearance; however, that does not alleviate the gynecomastic / glandular tissue that is usually behind the nipple.  I do believe chest fitness is an important component to "maintenance" of chest fitness in patients to prevent fat accumulation along the chest; however, the exercise will not alleviate gynecomastic glandular tissue.  I hope this is helpful. 

Unfortunately, by the time most men finally have their consultation with a plastic surgeon, they have realized that exercise, and to some extent, diet, have not improved their gynecomastia. While upper body workouts may improve your overall appearance, the protuberant appearance caused by the glandular tissue remains unchanged. 

If the gynecomastia is due to glandular growth, exercise will not improve this.  If is mostly fat,  that can reduce some with exercise but not the gland.  This is best treated with excision. Hope this helps.
