Just thought I'd post this photo my father in law took of me. So many CHL newbies are so overly concerned that everyone can tell they're carrying, especially if they're bending, reaching, or otherwise placing their bodies in a strange position in which their cover garment might ride up to reveal their handgun. I thought this might help put your minds at ease.
That's me, completely prone, taking photos of my 10-month old son at a local playground. See any guns? Even any printing?
On my right side, about 3:30, still completely concealed by my cover shirt, is my fully loaded Glock 23 in a Crossbreed Supertuck IWB holster.
I didn't even think about dropping down into this position to get the photo. Do this kind of thing all the time while carrying. Didn't think about it until my father in law - who knows I have CHL but probably had NO IDEA I was carrying that day (he thinks I just leave the gun in the car) - said "maybe you should consider being a combat photographer" ... I thought "oops, did my shirt slide up to reveal my Glock?" .... no, he just saw me laying prone like that and said that's what war photographers do.
Anyway, all you noobs out there you'll get more comfortable with carrying soon enough. Just remember, the vast majority of the population is completely clueless what you have under your shirt.
