Attach a resistance band to a door anchor. Place the door anchor at the bottom of the door. Connect the other end of the band to a D-ring on an ankle strap. Step away from the door and put your hands on the door for support or balance. Step back on the other foot and tuck your hands in at waist. The attached leg is straight and foot is slightly off floor.
Pull the attached leg back by extending hip. Return the leg to the original position. Repeat. Continue with the opposite leg.
This exercise can also be performed bending over by stepping further back.
