1 Leg Dead Lift

Start by balancing on a slightly bent right leg. Create wings of an airplane with the arms and turn the thumbs to the sky. Hinge on the right hip while keeping the knee angle the same. The torso will bow forward while the left leg acts like a teeter-totter and raises as the torso lowers. Keep the head and eyes up to keep a flat back. Try to keep the hips as square as possible when hinging. Once the body is parallel to the ground (should look like gliding airplane), hinge the body back to the original position and lower the arms. Repeat all reps on one side before switching legs.
