For the life of me I just cannot squat.
Below I compare my squats with a photo I found on the Internet.
I can squat lower with a wider stance, but I can only sit upright if I'm holding something. If I let go, I fall backwards. This is wide stance from front:

Ankle mobility is often said to be the culprit. If this is the case, how come the girl can squat with hardly any angle in her ankles? Nevertheless, I've worked on ankle mobility. Do I still need to improve?
I'm working on hip mobility now. I have good flexibility with lunges, but there does seem to be some tightness in the groin (sorry, not great with anatomy), e.g. with frog stretch. Could this be the problem?
I'm concerned that I can't reach anything like the girl's squat even when I'm holding something. I can't get my head around where my squat is going wrong or how I can ever get into the same position.
Will I ever be able to squat?!
