I did notice they're all slim and tall. BBW may have failure to launch.
Most long, high and triple jumpers tend to be tall and lithe and limber. Slim I suppose, as they're not linebackers, but not skinny. Very strong too. As a sportswriter I covered all levels of track and field for decades--yes, including international T&F and multiple Olympians and world WR holders. You'd be amazed at how much physical effort is expended and how many different parts of the body are called upon to complete a jump. Looks simple, but when you layer on speed, technique, and torque, well, it ain't so simple and it's exhausting. And for all of youse tongue-waggers, I'll grant you that jumpers are damn good-lookng top to bottom, especially bottom. Just my type (got suggestions for similar SPs anyone?). But 800/1500 runners are MCOT. My tongue hits the floor. I hear they're "fast" girls, too.
