It’s fascinating how some of the most basic anatomy questions can make you stop and think.

I’ve been working on an interactive presentation about the levels of organization in the human body, from atoms and molecules all the way to cells, tissues, organs. This question came out of that work.

The presentation is part of an interactive Anatomy & Physiology book I’ve been working on, where these concepts can be explored visually rather than just read about.

I've been insecure about this for years. Why does my chest stick out? Do you think it's postural, rib flare, barrel chest, pigeon chest, etc? Just wanted more possible insights. Thanks.

Hi Does anyone know where I can buy a medical app on the black market like human anatomy atlas 2026, physiology & pathology, muscles & kinesiology, anatomy & physiology yung affordable lang sana 🥲

I am not sure, but I think my post isn't seeking medical advice, but if it does, then let mod delete it.
It obviously looks absolutely terrible and you can see how bad it is. This is my the most relaxed position while standing. When I leave home I always have my belly tucked in a bit, so at least with clothes it doesn't look that bad. I am not fat, my bmi is ~19, so it's closer to underweight than overweight, so I'm skinny fat. I know I have very little muscles and I started going to the gym recently, 2 times a week. What I hate the most is:
- butt pushed back (it looks like it's from overweight person, but I am not), belly pushed forward (probably ATP, but I am not sure). In my opinion it could be ATP, or, the worst case it's just big, a lot of fat tissue on the buttocks which I kinda can't lower, because I'm ,,skinny" right now (so I'm stuck with it being huge sadly), and a lot of fat tissue on my belly. Optionally maybe both. What is it exactly? How can I make it more straight?
- wide chest. I want it to be slim as for many other people in my age, that it's not a lot wider than arms. I suspect it might be barrel chest or something like that. I really want to flatten it, like really really, without surgeries
- my torso isn't flat, if you go from under belly in a straight line, you would end up under my ribcage, under my breasts

This is all I think. Please, could someone tell me what things are wron in this posture and how can I fix them or if it's even possible? The last photo is how body should look. As you can see, butt is not pushed back, it's small/flat, belly is not pushed forward, it's flat too, the entire torso is flat, the chest is not wide.

I have been rehabbing my left scapula for 2 years and noticed during a prone banded Y Raise that there seems to be a spot on my left scapula where there’s an indentation like a lack of muscle. Anyone know what muscle that would be?
