found some solutions which kinda pinpoints you suck at it
1: implement it??? if you want it to then make it do it theres littealy no framed in the body parts
2: not sure what you mean by that but you can disable or remove that behaviour entirely
3: the limbs are too slowed diwn even the torso too so put it to at most 1
4: to disable fairy function make the legs have 6-7.5 grav
I know youre too laxy to do it but with the solutions you can atleast minimize the struggle???
