Lie on your side with your head and shoulders along the same line, i.e., straight body alignment.
1. Lift your top leg to an angle of about 70 degrees away from the floor, i.e., upward. Keep the knee almost locked so your leg remains straight. Hold the contraction at the top of the movement for about 2 seconds.
2. Lower your leg to the starting position and repeat next repetition.
Notes: This exercise primarily works the gluteus medius and the gluteus minimus. You can raise your leg in either of three positions: slightly forward, slightly backward, or vertically with the latter being most common. You can increase resistance strapping a weight to a cuff around your ankle or you can use the low pulley as you do when performing cable kickbacks.
