Hi Mangomelon, you are very brave posing on the net and asking for critique. :) I have picked up a few things that will help you. I find it helpful to watch what riders better than me are doing and using video people have taken of me to allow me to see faults in my riding. (eg, looking down, toes up, leg too far back, leg too far forward, duck feet, duck butt, and the list goes on :) haha)
I have added a few videos and screenshots from both your video and some pro's on youtube. I hope you find them helpful. If I haven't explained it well enough for you, feel free to ask for clarification. :)
You need to shorten your reins and have more trot coming into the jump. These will be important as you start jumping larger jumps. You must be able to keep the contact with your horse as you are helping them over the jump not just pointing at the jump and expecting your horse to figure things out itself.
Here is Caroline Powell on Lenamore. I know she is jumping a lot bigger than you are at the moment, but the basics are still the same. Look at how much rein she gives him. She keeps the contact even over the jump. She releases with her arms to avoid hitting Lenamore in the mouth as he is jumping, but she is there with him all the time.
You can also see it here on the 2009 Badminton highlights.
Here is a screenshot from the olympic coverage, same thing. More contact but releasing over the jump. olympics.jpg
Have everything sorted before you approach the jump. You should not be adjusting your reins on the approach. loose rein.jpg
- Have your reins at the correct length, a decent trot (or canter) - not too fast, not too slow before you start the approach.
- Keep your leg on to encourage your horse over the jump and also to help keep it on a straight line.
- Just sit there, wait and be paitent. Don't beat your horse to the jump, let the jump come to you. To try and get that to make more sense... Just sit like you would if you weren't jumping, tall in the saddle and don't lean forward. Leaning forward messes up your centre of gravity and makes it harder for your horse to get it's front legs over the jump. It also increases the likelihood you you stacking it should your horse decide to slam on the brakes.
- Look up and over the jump, not at it... again, looking down masses with your balance, center of gravity and makes you tip forward.
I have taken a screen shot of the time stamp when I was looking at in your video of the last few tips, so you should be able to see what I was picking up on. :) infront of horse.jpg
In lessons I know they tend to tell you to get into 2 point early while you are getting the hang of things, but IMO it can create bad habits as well as allowing you to feel what 2 point should feel like. Don't get into 2 point too early. It can become a hard habit to fix. Just sit still and rise into it as your horse rises to take the jump.
I also find having a neck strap (or in my case and old stirrup leather) around my horses neck to hang on to just incase helps a heap. You can see it in this pic of me and one of my boys... I even have a hold of it as we were approaching a jump that I knew he was going to get deep into. :) GKharvey.jpg
Good luck with your jumping and again, if you want any clarification... just ask :)
