Moving the thigh backward is the particular move in pulsing hip extensor exercise. This backward movement that stresses hips is called hip extension. Hip extension is an important move to perform in order to live a healthy life as the strength of gluteus, core, leg and lower body muscles help prevent injuries and discomforts. Hip extension exercise can be done by standing, kneeling or lying down. But perform hip exercises while laying down helps you more to concentrate the main gluteus muscles. Pulsing hip extensor exercise maintains and improves your body posture and decrease the muscle tension.
