I just wanted to update where I am today and thank Kirk for his help again. ... Thank you again for you help, and thank you Pole Vault Power!
You're welcome, Monica.
You have made very noticeable improvement!
One thing I'd like you to try ...
Once you jump to the split, try landing on your takeoff foot instead of your lead knee foot. I think that will give you a better body posture throughout the drill. At least that's how I did it, so it worked for me. The other thing is that you should try to jump harder off the ground. I don't mean to plant your foot like a highjumper would to jump harder. I mean more like a long jumper (keeping the forward momentum - without braking).
What is your longjump PR? Whatever it is, I recommend that you work on some pure longjumping (if you don't already do that event). The reason I ask for your PR is so that you know what it is today; then every month or two try to break your PR. With the hard training you've been doing (which I assume you'll continue to do), it will be a good boost to your ego when you see your LJ PR go up. And with that, I would expect that your PV PR would go up too.
