1. Alternating Lateral Lunges
This will work your outer hips, which are the glutes, and the outer sides of your thighs.
Start by standing with your feet together. Take a large step out to the side with your right foot. Both feet should be facing forward. Stick your butt back and lean to the right. Squat down as low as you can with your right leg, keeping your left leg straight. Then return to center and repeat on the left side. Continue alternating for 10 repetitions on each side.
