Standing hips circle exercises are perfect for stretching out the abductor muscles and core muscles. In theory they are very simple but to get the most out of a standing hip circle exercise you should do them as slowly as possible. This brings all of the muscles into play and helps to strengthen the hip and thighs. The exercise is straight forward, stand on one leg and lift your unsupported leg to 90° angle at the knee. This is the starting position for your standing hip circles and next you attempt to make as wide circles as possible by moving your knee away from your body and back to the starting position. Continue with this for as many repetitions as you feel comfortable and then change legs.
