Professional dunker Jordan Kilganon recently posted a Vine of himself nailing a box jump of 75 inches.

According to his Instagram bio, Kilganon is 6’1.” For the math challenged among us, that means Kilganon jumps three inches higher than his entire height! That’s quite a feat of fitness. Check it out (and note the awesome muscle flex from his friends after the jump): It looks like there is somewhat of a box jump craze at the moment. Remember J.J. Watt’s 61 inch box jump last week? Check out NFL star’s effort, and notice how he started from a standing position.
