Hips are one of the strongest joint structures in the body and are part of the pelvic girdle, which connects the lower and upper body. Known as a ‘ball and socket’ joint, the femur comprises the ‘ball’ and the hip is the socket in which it rests. As powerful weight-bearing joints, your hips enable your body to move forwards, backwards, inwards, outwards and twist in a full range of motions, all while fully supporting the weight of your upper body.
