How do you lower a pigeon chest?

Hey, you know i may not be the answer your looking for, but i have Pigeon Chest as well. I have talked to a few doctors about it and from what i can muster its that Pigeon Chest in Some Cases will normalize as you get older.( To me i find it highly unlikely) Although if your looking to hide it sooner i recommend Pushups or benchpressing to work on your muscles. As Pigeon Chest normally develops in tall skinny people you probably dont have much muscle mass to begin with so i would recommend running first till your endurance peaks up then moving to the push ups.

Other Options include Several Painful Surgerys... an Exterior Brace that takes 2 years to completely do the job etc mostly expensive stuff

In the long run, it really shouldn't matter if you do or don't. Most people care too much about there issues and looks to really care about yours... As you get older you'll see.

Well hope i have been even a little help.
