Adequate hip mobility, indicated by the ability to squat with the hip crease below the knee, stand on one leg and pull the knee past 90 degrees, and perform a sit-to-stand maneuver without assistance, is associated with better health and potentially longer lifespan.

“According to Dr. Kelly Starrett (@thereadystate), you should be able to squat with your hip crease below your knee, stand on one leg and pull the other knee up past 90 degrees, and lower yourself to the floor and stand back up without using your hands or dropping a knee.”
