How long have you been vaulting? If you're just starting, that's awesome. I know a couple of high schoolers that struggle to clear 7' 6''... If you've been vaulting for a few years, that's still pretty good. Put up some video!
I say that's pretty good considering youre a sixth grader because not that many 6th graders even get the chance to vault. You're a step ahead for high school. Good job and good luck!
for half a year of vaulting thats pretty good. and vaulting 3 days a week is a geat oppurtunity. its really good that you are focusing on the technique. as you get older and you grow and are able to build alot more muscle, the heights you can reach will increase dramatically. the key to reaching good heights in polevault is a strong, fast run and a good plant. so keep it up, youre off to an awesome start
