For example, your elbows and knees are hinge-joints. They bend back and forth in the same direction. They don't allow much rotational movement. If you do over-rotate those joints you'll often incur a sprain or more severe injury.
The hip joint is different from the knee in that it is a ball and socket joint that allows your hips to move both rotationally and as a hinge joint. Here's what you need to know: Your hips are designed to move best as a rotational joint. If you walk, hike or run and don't rotate your hips adequately, your hips move like a hinge joint. Too much of this type of movement in the hip joint causes over-use injuries/damage.
To practice what a rotational movement of the hip feels like, do the Hula. Really!
- Stand with feet shoulder width apart and knees gently bent.
- Rotate your hips in circles, first clockwise, then reverse directions.
- Now, walk backwards slowly and notice how the hips automatically rotate, taking the leg back.
- Slowly walk forwards, seeking to maintain the sensation of hip movement. Remember to keep your knees slightly bent.
