Calm, forward, straight

Start with the relaxation of the mind
Then the relaxation of the jaw
Then the relaxation of the poll.
Only when you got that, can you expect to work with the horse back and not against it.
Work collected to keep the horse in a perfect balance and helding his back strongly.
Then let the horse give you his energy and use it well...
Bends, curves, a lot of small steps, some big strides and rein-back, everything has to be easy and flawless.
If your athlete is put in good condition of work, he can do miracles !
