I don't really mind the editing. It's easier to crit some weird editing rather than a video that looks like it was recorded with a calculator
In addition to everything said above, (your hands are really flying everywhere, as well as your body, and leaning into turns)...
It looks like you're really riding 'loudly' (I don't really know how else to call it). Pay attention to trying to stay in rythm with your horse, not just bumping around in the saddle. Use your hips to absorb the canter a little bit... Idk how else to explain it.. Not only is bumping around uncomfortable for the horse, I can't imagine it feels too good on your own backside either!!
Another thing I see in some
clips, is that you're really leaning back a lot, which throws your legs into a chair seat. Sit so your ears, hips, and ankles are all in a straight line
. (sorry, equitation nazi here...)
Your lead changes look good!
Like the others said, barrel training isn't just running around aimlessly and turning in circles. What you should be doing (and I'm no expert, but I barrel race sometimes) to get your horse ''ready'' for barrels, is some flexing to soften him up, and getting him in good shape (hills, trot poles, conditioning). Then once you get the actual barrels, you can start WALKING the pattern... For weeks... until you have it down pat. Then trot it, then lope it, then you can try it full out once you've got the pattern down really well (just be sure not to do it too
much, then your horse will get arena/barrel sour.) Also do some drills, and mix up the pattern a little bit so your horse doesn't get to where he thinks he knows it better than you do; so he's still listening to you.
Hope I helped a little
