Our coach regularly makes a point of walking around, deliberately trying to get in our way. In that situation, as with any comp situation, I am highly tuned to what DP is doing. Half the time he forgets the routines, and I never really learnt them properly. I just follow him wherever he goes.
We have this neat little following exercise. We stand in ballroom hold, and DP will have his weight on one foot. My job is to sense what foot he's on. Then he will move in a random direction. I follow (or at least, I'm meant to). If he has his weight properly placed and compresses, it is nearly impossible to not follow. We practise it lots, in the hope that it will transfer into a competition scenario. There is no communication beyond body language.
thats a great excecize - wonder if I can get DP to do it...
