Turn on the Forehand
[As additional resources, links to book reviews and book purchasing information can be found beneath the quotations when this information is available.]
In the turn on the forehand, "The aids should be relaxed slightly after each step, to reward the horse."
"The horse's first natural evasion is to walk forward. Your hands must immediately say 'No.' Having achieved that, they must return to normal contact or your horse will make another evasion by backing up."
"Don't let him [your horse] give you more than you want. When you ask for several consecutive strides, the timing of your leg aids is what he should obey."
"...it [your leg cue] becomes push, ease, push, ease, synchronized with the movement of the crossing...leg. On the horse, you do not remove your leg between pushes, just soften it for easing, and then push again."
"A horse with a blocked back...tends to move backward when asked to turn-on-the-forehand. Executing the turn while moving diminishes this tendency and significantly increases the benefit. Moreover, crossing of the front legs significantly loosens the shoulder region."
