Hey guys, I've been doing triple jump for two seasons ( I'm a sophomore) and my PR is still a depressing 37'7". I don't know what I'm doing wrong. I feel like my form is at least decent but I still don't jump far... Is it just because of no strength? Btw this video is not a full run up to the board, just a few steps. I don't have any clear videos of jumps from meets.
How can my form improve and how can i get better? (like hopefully 39? 40?)
