I'd like to pipe in on poise. In Rhythm dances and most notably to me, Cha Cha and Rumba, the man and woman should keep forward poise. That is, both should carry their weight on the balls of their feet at all times, helping to cause the connection between the partners to be positive, or a slight push against each other, almost all the time. I believe that only directional change from stepping forward (for the lead) to stopping or stepping backward should produce a momentary negative, or pulling, connection. And I emphasize the term "momentary". Even when the lead is stepping backward as in triple progressives, the couple should still maintain a positive, or pushing connection.
I have only been dancing about a year, so I could have some detail wrong in my explanation of poise here. Anyone wishing to add or correct what I have said is welcome to, I still have lots to learn.
