Rigify rotation limits on bounding box to small

So I’m trying to make a backflip animation on a rigify rig so we the model to full fk and tried to rotate it the problem is it only rotates 180 degrees in either direction plz help

It’s been a while since I animated a rigify rig but I have some experience; what bone are you trying to rotate 360 degrees? There could be a “Limit Rotation” constraint on the main body bone but I don’t remember rigify rigs having that.

EDIT: It could also be that the rotation mode of the bone is set to the default for bones, which is Quaternion. Change it to something like XYZ Euler and it will be MUCH easier to flip.
