Classical dressage purist Daniel Pevsner was a fellow of the British Horse Society and a former pupil of the Spanish Riding School of Vienna.
He also studied the Alexander Technique extensively and observed many parallels.
When a horse is broken in, then ridden awkwardly or forced, it develops patterns of muslcular tension, much in the same way as humans do from years of sitting at school desks etc.
Mr Pevsner's approach to dressage was sympathetic - horses weren't forced - they enjoyed being trained, it was a treat!
If dressage is used sympathetically, just like Alexander lessons for people, habits of tension are elimianated so natural 'good use' re-emerges.
It's an uplifting process and when both are combined the results are wonderful.
