Hi there :)
What an absolutely beautiful mare! What an honor and priveledge to beable to be with her eh? You both look great together and I can see how proud you are of not only yourself, but of her. The first thing I noticed, is that it does appear that your saddle is too small for you. This will effect your form while in the saddle, your balance and your centeredness. 1)
Lets start with your leathers - do you see your feet? See how your toes are lower at an angle, than your heels are?
That is beacuse you are reaching for your toes for balance, when in reality - it should be your heels doing their job.
Your leather length is a good length for you - but somewhere along the line from your upper thighs to your calf, you are gripping somewhere - blocking this flow of natural weight from your upper body to your heels.......which is not allowing your heels and ankles to do their jobs.
Your heels must beable to sink and absorb all your bodies weight so that they can anchor you in your tack, so you can get that feeling of balance. Your ankles, but be allowed to be shock absorbers - your heels and ankles must be allowed to work together.
So - lets re-establish your lower legs, and teach them to do their job accordingly. Open your legs up, allow your bodies weight to flow down into your heels. Allow your heels to sink.
Your inner calf should be on your horses side - not the back of your calf.
Work on lengthening your legs. Open them up, stretch them down - allow your heels and ankles to do their jobs.
Secondly, I notice that you are not using your core at all. You must establish a strong core, to be an effective rider. I notice in a few of your pictures, that you have a hollowed out lower back - which you must work on correcting.
Imagine a bowl of water the center of your belly. As Sally Swift would say - that bowl of water is your balance and effectiveness. The moment you hollow out your lower back, you've now allowed that bowl of balance to gush out the front of you. The moment you roach your lower back, you've now allowed that bowl of balance to gush out your back.
We want balance. Work on straitening your lower back, pulling your tummy inwards and start using it! Work on your belly, allow it to strengthen and support you - through that, you will gain a more effective seat, stabillity and balance.
Thirdly - due to your lack of strength in your center, this has effected your upper body.
See how low your hands are carried? See how open your elbow angle is? See how sloppy your shoulders are? See how you are always looking down?
All this is effected due to the links in the chain being disrupted. Your body parts, are all links in a chain. Each one must be working to aid the others surrounding it. Same with your body parts - each one must be working properly, to aid your other body parts.
Without one, the other cannot do its job properly.
You know - like the tune "the leg bone is connected to the thigh bone. The thigh bone is connected to the knee bone...etc, etc." Same idea here -
Sit up tall, bring those shoulders back, CARRY your hands, close that elbow angle.
You MUST have an effective hand carraige to aid yourself and your horse. When we carry our hands low...the rest of our body follows or vice versa.
You drop you hands, you elbows open and tighten. Your elbows open and your shoulders drop. Your shoulders drop, your head follows - again, or vice versa.
When we carry our hands low like that, we have no where to give. No where to take. We cannot lift, aid, support, soften, be softened. We cannot ask, be asked.
We must learn proper hand carraige to aid our horses.
Bring those elbows to your sides.
Right now - your hands are dropped near your horses withers. You pull them down into your crotch - and they are very ineffective.
- So lets work on opening your legs. Re-establsihing your inner calf, and allowing your heels to deepen and your ankles to absorb.
- Start using your core. Strengthen and use your belly muscles.
- Straiten that lower back.
- Sit up tall, lift your shoulders, close those elbow angles and carry your hands.
- And look up
I hope that helps :) Enjoy! And have fun!
