She's ridden in a double bridle. Although I'd ride her in a snaffle if I could, it's not my choice as she belongs to the riding school. I don't really know how the double bridle works, I'm pretty ashamed to say that all I do is pull back as I would on normal reins so some tips on this would be apprecciated, just don't murder me. ;)
Thanks for your help guys. :3
This worried me to no end!! Actually in the video it looks like a pelham, NOT a double bridle. Still a concern though. You should feel free to ask such questions of your instructor and your instructor should be making sure that you know how to use all your tack and equipment, as well as the differences between each.
I have my own concerns about a rider starting out using a pelham but for the moment I'll leave it
Now, was that you riding the horse in the video? If so here are a few considerations for you:
1.) Give with your hands a little! You are literally attempting to brace the reins (both of them I might add) in an effort to keep her at an even pace. This causes your horse to brace against the pressure. Whilst it may work for a few strides, once she braces against the pressure and stiffens her jaw/neck muscles she is free free free to take off. You need to ride with soft hands. Get her working FOR you, not IN SPITE of you.
When she canters, your hands should gently rock with her natural motion to allow her to relax onto the bit and the contact to be even and consistent. Use the snaffle rein to keep a nice rhythym and get her flexing a little more to the inside. I think you should be doing plenty of walk and trot serpentines to encourage her to relax her neck and back muscles and encourage her to flex in each direction before you even ask for a canter. Set yourself up for success!
Have a look at the video of her trotting at 1:26 - your hands are stiff, low and there is an incredible amount of pressure on both reins as you struggle to get her to lower her head. She is resisting heavily - have a look at her neck and the way her mouth is open. Not a happy camper at all. Work on having her supple in the bridle before you do too much more.
And get off that lower rein!
2.) Your position needs some adjusting. Have a look at the video from 2:41 - your lower leg has slipped quite far forward putting you in a chair seat. The distributes your weight to the back of the saddle allowing your legs to slip forwards. When you look at a photo of yourself you should be able to draw an invisible line from your eye to your knee to your toe and another line from your shoulder to your hip to your heel. This puts your leg neatly under you, just at or behind the girth and sits you up tall in the saddle, much more able to use your seat effectively.
Good luck and talk to your instructor about the correct usage of your tack, it is very important to your education and also to your horses happiness under saddle!
