Roughly, where is the axis of rotation for the action of returning from a forward bend ?
L3
The axis of rotation for the action of returning from a forward bend can be described as a posterior tilt of the pelvis in the sagittal plane. As you come up from the forward bend, your pelvis rotates back towards its neutral position, with the tailbone lifting and the pubic bone lowering. This movement occurs around the hip joints, which act as the axis of rotation for this motion. Additionally, the lumbar spine also extends as you come up from the forward bend, adding to the movement of the pelvis and the axis of rotation.
