Spinning is something that can only be learnt over time, and the best way it to build up slowly, start with single turns feet together, step to the left, prep body left then turn right finish with feet together, then do the opposite to turn left, concentrate on turing shoulders first and let body catch up, obviously you need to work on your head to learn to spot correctly, keep arms out in front shoulder level first, this is the easiest way to keep your balance. Once you can do that perfect single turn, whitch will take time you can move on.
Then move on with a 1 1/2 turn this will improve your spotting and control, use the same technique and spin only on 1 foot, your head should spot the half turn first then the complete turn, most people can learn to turn in a short time frame, the hard thing is stopping in the right place, your head will control this. Always turn one way then the other so you don't learn to only spin one way.
Once you have done this keep going, same technique for 2 then 21/2, 3, 31/2 you can keep going. Once you can learn to control your centre you can learn any type of spin that much easier.
Hands on your hips or arms above the head, are harder to execute, because you will need them to generate power as you are learning to turn, eventually you can use your core and your head to generate the power.
One of the biggest misconceptions is to lower your body and bend your knees while turning, you can bend your knees during the prep but lift your self up during the turn, keep your head up, shoulders back and relaxed and generally good posture, without locking your knees, this will help to keep you centre.
Most artists will give you different answers of how they create there power in turns but it will generally be shoulders, core or head, not legs or hips. For me it is just spotting quicker.
Most of them learn't using this excersise, as it is a sure way of teaching you to turn. I built up to being able to do around 4 turns consistantly just by doing the excersises for 5 minutes a day for about 4 months, before this I coulde barely do 2 turns without falling over.
Obviously there is alot more technique for actually leading and following with a partner but if you can spin on your own, being led is not hard to learn.
Now do I get a prize for the longest first post in the forum, or has some one posted longer
