Hip flexor exercises strengthen the muscles in front of your hip. The hip flexor muscle attaches from the hip and also to the vertebrae in the lower back. Strength training for this muscle is important because it is used daily for standing, walking and other movements that involve the legs. Keeping the hip flexor muscle strong improves balance and posture. The seated leg raise is a simple effective exercise that targets the hip flexor muscle group, also called iliopsoas. To do this exercise, sit on the edge of a bench with your legs extended to the floor. Grasp the edge of the bench with both hands and lean your torso back. Balance your weight on the edge then raise legs by flexing your hips and knees inward while pulling your torso a bit forward for balance. Extend hips and knees outward and lean your upper body back to counter balance.

Seems like my favor for strengthening hip has a good reason after all.
