The reason why people end up with a horse on the forehand, after they've created the back end energy - is because they are not supporting through the outside rein, and driving inside leg into outside rein.
Far too many overuse the reins. The reins do not control the face -the reins control the shoulder.
Your reins do nothing more - nothing less. You control tempo, flow, rhythm through your seat - not your hands. Yes, you must have supportive hands - but not forceful, over active hands.
You do not get a horse in a collected frame through your hands. You get a horse into a collected frame after consistant, persistant, continuous work through correct aids vai Seat To Legs To Hands.
Support through the outside rein - your outside rein prevents that energy gushing out the front end.
Nothing more, nothing less.
Incorrect riding is front to back.
If you get the wrong answer when you are asking for impulsion from the back end - you aren't asking the question correctly.
You must ride on the 3 points of your seat, always. There are times when you ride on crotch via 2 point over a fence, and there are times when you rock onto your seat bones...via top level movements in dressage horses. Aside from that - always on your 3 points.
You lighten your seat, via weight flowing through into your heels. Your heels take the brunt of all your energy, all your weight. By opening up your knees *because you never grip anyways* you allow the weight from your upper body to flow down into your seat, flow down through your legs and into your heels.
Ok - so you activate the back end by pulsating your seat bones. You ALWAYS use your seat bones.
*side note* people like to turn circles via reins....when it should come from inside seat bone, inside leg and outside rein
Use your seat bones to activate the back end by pulsating them in accordance to the back leg movement. Left, right, left, right.
You must be balanced, through your heels, to your seat, lower back, to your upper body.
Your lower back must never be roached, must never be hollow. You hollow your lower back - you've now lost your core and your balance gushes out your front end. You roach your lower back, you've over activated your core, and your balance gushes out your back.
Must be just right, like Goldie Locks and the 3 Bears - lol.
3 points, strait lower back, tall upper body balanced over horses center of gravity.
You do not deepen your seat - why? Because of a few reasons.
1) You must remain balanced over your horses center of gravity. Your upper body must not go behind or infront of the verticle. Never.
2) Over active seat, creates a horses sensative back to drop..and not activate...which is important on getting a horse to utalize their essential muscles to build a topline to get the reached goal of "on the bit"
3) You become too loud for the horses movements.
Once you've recieved the wanted movement...you lighten your seat thorugh your heels - and now your legs take place. Same pulsating...left, right, left, right......then your legs act in lifting the back and the ribs.
NOW - your horses back end is moving. Your horse is tracking up, and your horses back is lifted - now all the important muscles are being used...........
All the while, you are supporting via outside rein.
The MOMENT your horse gives to you, you give back. Release, praise. Releas thorugh fingers, not compromising your support.
Inside rein has very little function.
Outside rein, prevents energy from gushing forward. Outside rein keeps energy recycling. Inside leg keeps the impulsion, activate seat when needed.
Seat To Legs To Hands To Soften.
The headset comes last always.
