Posterior vs anterior pelvic position
Are there any benefits on being on anterior pelvic tilt in climbing?
I always had terrible APT and duck feet throughout life due to sitting all day (Software engineer + No-life gamer back in the younger days) and one problem I always had was with my posterior chain. Always felt like I could not engage my core on overhangs. and even during indoor coordis I would be in a weird position with my ass super out of the wall which I felt like hampered my climbing a bit. One key takeaway was I never understood what people meant by "squeeze your glute".
I had a short break due to some injuries and spend time doing rehab + gym and then realized I could squeeze my glute only when I tilt my pelvis in a posterior position. Before this the only thing I manage to do was squeeze my erector? So I'm wondering if this is the position that I should permanently be in while climbing so I can properly utilize my glute and maintain my posterior chain.
TLDR: Is this the right way to look at this, always stay in the posterior pelvic tilt position so I can squeeze glutes or it's not that simple and there are benefits of being in anterior pelvic positions? Or both is wrong?
