How's it going Laucy? Is your jive feeling better? I only asked the quickstep hop question to see if it was your core. Latingal's hit it on the head there with activating your core. So much movement in dancing comes from the core, from controlling our posture and balance to creating energy for fast movements. Unfortunately, I think it's something we have to get in touch with ourselves; fortunately the more we dance, the more we strengthen our cores and will hopefully achieve that look of effortless movement. In terms of tricks, I don't think there are any, but it's nothing that a little hard work and going back to basics won't fix. I usually stand facing a wall and lightly press my fingertips against it, arms outstretched in a double hand hold. Then I just work on the feel of the basic, connecting the feelings of the movement with the muscles being used. You'll feel an alternating compression and extension on opposite sides of your obliques as you're generating the movement for the rock and chassé, and should feel as you switch your centre of balance across a chassé that there's a slight inwards "pull" in one arm and an outwards "push" in the other and this switches around as your centre moves. You'll get the feel of it, and keep correcting as you go. If you're feeling unbalanced when dancing a basic in hold, perhaps your connection with your partner isn't quite in sync. To me it feels like I'm aiming for perfect balance, catching myself at the end of a swing, without too much weight that switching the other way will take more time and energy, which would result in a heavy feel, but not off balance, which would look uncontrolled. Don't know if that helps, but I hope it's going well!
