Somebody was asking for a few excercises to help understand dancing. I've lost them somewhere. Don't dance outside your circumference when stepping to the side. Stand feet together knees straightish. Point a toe to the front and draw a half circle to the rear. Now bend the supporting knee and draw a half circle again. It's bigger isn't it. Bend it some more,its bigger still. You must dance within that circumferance. When we watch tapes we only see what appears to be a large step to the side. What we need to do is take note on how much the supporting knee is bending and is being used..

I know this isn't on the 'circumference' topic, but it is on exercises to help understand dancing.
I think i have 2 good exercises to help develop good leg and foot action.
1)walk upstairs without your upper body/head moving up and down - keep it moving upwards in a straight line. Very tiring on the legs, but you have to develop good co-ordinated leg and foot action.
2)Walk backwards uphill (not too steep a hill at first) Doing this requires you to push hard with the standing leg, and this feeling is obvious doing this exercise. Explain to your neighbours that you're developing dancing skills!!
