Justin Darlington World Record
I was wondering, have you seen the video of TFB member Justin Darlington, doing a 68.5 inches box jump? This video is incredible, and he is a good example to demonstrate that sometimes, impressive box jumps does translate into impressive vertical jump.
VerticalJumping.com Response: It is an impressive display, and yes, Justin has huge hops. People with impressive jumping ability will always be able to produce big box jumps, but it isn;t always the case where people who can do big box jumps will be able to produce big regular jumps.
