"Lightness, whose characteristic lies in the elastic and springy flexibility of all joints and muscles, can only be acquired after all resistances have completely disappeared, that is, with the disappearance of all inopportune contractions." ~ Alexis François L’Hotte
An exercise to check if you are sitting straight and putting your weight equally down into both stirrups is to stand straight up for a few strides (at all three gaits), and notice which stirrup you have to consciously put more weight into to keep yourself balanced.
To help your horse make a softer, more balanced canter depart - set him up for it, and then think of allowing him to canter, rather than asking strongly. If you push too strongly, your horse is more likely to push hard with his hind legs into the canter, and begin the transition on the forehand.
Excessive bend in the neck, whether lateral (usually to the inside), or longitudinal (behind the vertical) disconnects the haunches from the rein aids and allows the horse to remain locked up in other parts of the body, such as the poll and hips.
Horses that have a smooth and naturally balanced gallop stride often have longer careers in this sport. Keep that in mind when looking for an Eventing prospect.
The use of "half steps" in your training can be very beneficial, as it can help the horse to understand the idea of engagement without increasing speed.
Position your horse in a very slight shoulder fore before every movement or transition, to help him engage his inside hind leg and really step through from behind.
"Many riders in the name of impulsion, put too much tension in their horses. Others in the name of lightness, have their horse 'abandoned' (without a sufficient connection). The truth of equitation is in between those two extremes." ~ Nuno Oliveira
The quality of the contact that the horse will give you is largely dictated by the amount of hind leg activity at that moment, and how much the energy from that activity is able to flow in an uninterrupted way through the horse's supple and permeable body into your hands.
The old masters learned early on that riding accurate arena patterns is the key for improving a horse's balance and straightness. Always keep this in mind in your training.
"Through the energy of impulsion mobilized from within himself, the horse is now prepared, in his physique and emotional attentiveness, to respond instantly to the slightest indications to change his tempo, posture, direction or gait." ~ Waldemar Seunig
From Facebook fan Sarah Feathers ~ "When your horse likes to run and/or buck before and after jumps, it is much better to 'hold' with your core than snatch your reins."
"Whenever a horse has learned a new movement or a new aid in its basic form, the rider should give him a break and deliberately ride something else for a few days or weeks. When he returns to the movement, he will notice how much more easily the training will proceed." ~ Reiner Klimke
"Every horse is different, but you learn to compare, what to do in this moment with this particular horse, and that takes time. Dressage doesn’t go fast, this is the difference between our young riders and our more experienced riders." ~ Reiner Klimke
"If the leg is required at every stride to maintain the impulsion then it is necessary to return to the basic priorities again in order to teach the horse to remain active and forward thinking without constant use of the leg." ~ Chris Bartle
A word about the double bridle: The curb bit is a tool for refining the aids, not for applying more force. If the double bridle is used because otherwise the rider can’t ride his horse on the bit or because he can’t control it, neither the horse nor the rider is ready for the double bridle.
"Working-in is one of the most important aspects of dressage. You want your horse to be long, round and stretching before you start more taxing work, to get the muscles in front of and behind the saddle soft and working – gymnasts don’t hop straight onto the top bar! Ideally, walk for 10 minutes to start with, but if your horse is fresh, it is best to trot on to settle him down." ~ Carl Hester
"The inside leg assures that he is consistently looking for the outside rein. Come on, get him sensitive. If you’re too busy with your inside rein, it takes the focus off the inside leg. Try to get rid of the thinking that everything will fall part if you give the inside rein." ~ Stefan Wolff
From Facebook fan Gabby Ballin ~ "Just because something went bad once doesn't mean it'll go bad again. If you anticipate a problem, your horse will too."
"Only use the spur to correct. The spur is not intended to ride a movement. It cannot just support the gait or the movement. Make a clear correction with the spur. If you are constantly giving your horse an aid, he will get numb to it. " ~ Steffen Peters
"Horses have taught us that progress in learning takes place in an environment of contentment. Fear and tension block success. Boundaries must exist, be clear, and be consistent. Within those boundaries our horses are encouraged to express themselves." ~ Steuart Pittman
"It is not dressage that is difficult, it is making it look easy that is difficult. Some horses are born with presence, while others you can train presence. Either way, dressage is about improving the paces." ~ Carl Hester
"It is so important that you do a proper warmup and make sure everything is loose and supple, then give a walk break – and then you can start sitting." ~ Ingrid Klimke
"The difference between an incorrectly compressed horse and a collected horse is that the collected horse can put his nose toward the ground (stretch) while staying round." ~ Nuno Oliveira
When training a young horse you should be fairly single minded. Your main goal should be to build your horse's confidence in you, so that they think of you as a fair but strong leader.
Your ability to develop following hands and arms depends on the quality of your independent seat, which is required to allow you to give precise aids while following your horse's movement.
When doing lateral work, every time your horse steps nicely under his body with his inside hind leg, you should feel him stepping up into the connection of your outside rein. Be sure to make good use of that opportunity to soften your inside rein. Every single time.
