Sit on a chair or bench with your back straight and feet flat on the ground. Place a resistance band around your thighs, just above your knees. Keep your knees bent at a 90-degree angle and your feet shoulder-width apart. Engage your glutes and slowly rotate your knees outward, pushing against the resistance of the band. Pause for a moment at the end of the movement, then slowly return to the starting position. Repeat for the desired number of repetitions.
