does anyone think this could help the hopeless spinner? the spin and turn lesson last month was great......... i'm practicing. is ballet a practical way to get help/

My "smirk" got deleted in that crotch joke.... Is this some kind of a joke??

I would'nt dismiss the "barre" exercises entirely. Those exercises build balance and muscle strength, which is what the ballroom dancer requires as well. It may be a little boring and hard work initially but when the ballroom dancers sees results on the floor. They will be more than happy to spend time there.

The modifications I would make to a barre routine are:
1.Amount of turnout of the feet.
2.Dancers should be allowed to wear their ballroom dance shoes.
3.Lines and shapes should be borrowed from ballroom.
4.Exercises that enable couples to work together (with a ballroom flavour).

Other useful techniques would be:
Spinning (all types include partnership spins)
Spotting while spinning.

I agree, standing at the barre can be boring, mainly if the barre-tender is busy elsewhere..

Thanks to everyone for your advice, even the joke was good. Keep the comments coming. ;-p

show them how to stand straight with a long back and how to relax the muscles of the back while stretching.
we do simple ballet routines before each training and its good.
ballet arm movement is different from latin arm movement (the source of latin arm movement is hip/upper body), also spins are done by a different way (done not so "classical style" as ballet).

May I suggest something that every latin dancer could use - body isolation. Perhaps you could teach them how to isolate the ribcage whilst doing the latin action..?

Then there is the spinning and pirouttes, chene turns (pardon my spelling of course), and spotting..

Oh, and you can tell them what those male ballet dancers wear to enhance their crotches. Surely they cannot all be that well endowed..
