Is this an OK way to flatten my chest?

[Tyler90210]

Is it OK to use the back of my arms, to push on my chest to try and make it flat? It seems to work at least a little. I have a pretty small chest. Small enough that I don't need to bind and look completely flat in a button down shirt. And I need to wear a men's undershirt to look flat in a T-shirt. And the pushing seems to make it look smaller after I do it.

Lately my chest seems a little bigger. I think I am retaining water because of the Depo Provera shot. And that's why my chest is looking bigger. I think the pushing helps maybe move the retention somewhere else? Or maybe it just flattens me in general? I don't know. It just seems to work.

So is it OK to do that? I usually do it for like three minutes at a time a couple of times a day. That can't cause any problems with my lungs right? I don't think it can, but I just want to make sure. And I'm like 99.9% percent sure it won't cause any problems pushing somewhat hard right above my heart, right?

If there's no problem with doing it how I do it, could I also up my time per day?

For what it's worth, I used to do this when I was younger, like 12, and never had any problems then.

Thanks guys.

P.S. Anyone else do this?

You're totally fine--the lung problems come with wearing very tight compression shirts day after day, hours at a time, for years.  However, if you're looking for long-term chest size reduction I don't think this method will do it--the reduction you see afterwards is probably just a temporary compression of the tissue there that will expand back to normal size afterwards.  Think about when you wrap something really tightly around your finger and then unwrap it--you may still see the indentation of the string, but after a little bit it returns to normal size.  However if you're having good luck with this, that would be awesome!  Full speed ahead!
