Chest size??

[Orbit56]

So I’m just curious what is the average circumference of a 15 years old chest and how measure it... for some reason I feel like I have a big rib cage and big build. Anyways idk if that makes sense, will working out and push ups help? I

the average man has a 42in chest so take a little off of that since you haven't finished growing yet, but working out really will increase it depending on the workout because you'll gain more muscle mass in that area.
