Hey Brandon, great comeback story!
And great vid!
That was a very smooth vault over 14-3! Your swing and extension are both excellent, especially given your lack of training (and confidence) over the past couple years. You have some very good vaults ahead of you - much higher than this. Just keep working on your run/plant/takeoff. Your swing and extension are already very good - just make it more explosive by hitting your takeoff at top speed. Drive up and into the pole on takeoff - don't let the pole pick you off. Jump UP and INTO it.
I see you're on a 14-180 now. What's your grip? Do you have a good series of poles ready to move into when you get into the 15-foot range? You'll need them.
Change your PR on your profile to 14-3. Then change it again when you break the valley record!
But don't get too far ahead of yourself. Your next barrier to break is 15-0, then 16-0, and THEN 16-3!
I'm not going to say it's impossible, but most vaulters don't up their PR by much more than a foot per meet - at the most. So you'll probably need at least 2-3 good meets under your belt to hit 16-3.
Keep training hard and smart - and safe! Good luck!
