Stand in front of your partner nad have him place his hands on your shoulders. Now start to raise your feet off the ground one by one (not much, just off the ground) and your partner will feel the imbalance and guide you with the direction you have already given. Minimize the movement in the upper body so you can stay upright and your partner will learn to blend with the motion and become more aware. Change roles and use different placeholds and learn how you move.
