This drill helps in getting past the push/pull movement and into moving ourselves as one unit. Continuous attention to this practice will give you more fluidity in motion and thought.
Sit and start moving from one side of the area to the other with no contact with the ground with either your feet or hands. Keep your breathing continuous and and your eyes relaxed from focusing on one direction or object.
Repeat the previous drill but have a partner walk through where you are and avoid impact. Continue to work as your partner or partners try to push you and pull you with their arms and hands as you move about and then add the lower limbs in the fun.
The more you pay attention the more it pays forward afterwards.
