I've noticed a lot peoples rib cage aligns perfectly with their pelvis, chest to junk making a perfect straight line provided they aren't fat.

My chest definitely bulges out past my pelvis a bit, is this because I have no muscle or do I have bad skeleton genes?

I am lifting now, hoping some muscle helps me. Still losing fat too.

Got 20 more pounds to lose to reach 150 pounds at 5'10.

No loose skin yet, but I've lost 96 pounds so far, can I still gain significant loose skin for these last 20 pounds you think?

Am I probably gonna be fine with no surgery as long as I build muscle?
