Change the reign?

Question

i have a dressage test tomorrow....and i was wondering - when it says "K X M, change the reign " what does that mean?

Answer 1

means change to the other side, if you were riding on the left side, change the rein to the right side, its kinda hard to explain. but change the side you were to the wall?  you can do this by going down the center lin in any gait,  then turn to the left, go right around the school, the go down the senter line again, but this time turn right.

hope this helps!!
