The hip joint itself is inherently very stable but its alignment during movement is influenced by a range of structures in the leg, pelvis and lower back.

Ideally your hip, knee and ankle will maintain a stable vertical alignment throughout the pedal stroke. Often the first indication of a deficit in hip stability or mobility is a visible deviation or tilting of your knee alignment during pedalling or a sideways rocking of your pelvis. Massage therapy and corrective exercises tend to have a major role in improving hip function for cycling but seat position and crank length changes can also be a critical factor.
