Fosbury, who was born in Portland, Oregon, first started experimenting with a new high jumping technique at age 16, while attending Medford High School.
Fosbury had difficulty competing using the dominant high jumping techniques of the period.
In his sophomore year, he failed to complete jumps of 5 feet (1.5 m), the qualifying height for many high school track meets.
This dominant technique, the straddle method, was a complex motion where an athlete went over the high jump bar facing down, and lifted his legs individually over the bar.
Fosbury found it difficult to coordinate all the motions involved in the straddle method, and began to experiment with other ways of doing the high jump.

Fosbury later recalled, "I knew I had to change my body position and that's what started first the revolution, and over the next two years, the evolution."
At first, he tried to use a technique known as the upright scissors method.
In this method, a jumper runs upright towards the bar, facing forward, and during his jump lifts his straight legs one at a time over the bar.
High jump rules stipulate only that competitors must jump off one foot at takeoff; there is no rule governing how a competitor crosses the bar, so long as he or she goes over it.

As he began to experiment with this technique, he gradually adapted it to make himself more comfortable and to get more height out of it.
Nonetheless, it was nowhere near as coordinated as a well-performed straddle method jump, and one historian has referred to Fosbury's early attempts as an "airborne seizure", but during the latter part of his sophomore year and the beginning of his junior year, it began to produce results, and he gradually was able to clear higher jumps.

Gradually, Fosbury shifted his positioning during the jump, such that by his senior year he had begun to go over the bar backwards, head-first, curving his body over the bar and kicking his legs up in the air at the end of the jump.
This required him to land on his back, but prior to his junior year, his high school had replaced its wood chip landing pit with a softer material, so he was able to land safely.

Luckily for Fosbury, replacement of landing surfaces with foam rubber was becoming common across the United States in the early 1960s.
Sawdust, sand, or wood chip surfaces had been usable previously because jumpers using the scissors technique were able to clear the bar while upright and then land on their feet, while those using the Western Roll or Straddle made a three-point landing on their hands and lead leg.
In the late 1950s, American colleges began to use bundles of soft foam rubber, usually held together by a mesh net.
These bundles were not only much softer, but were also elevated about 3 ft (0.91 m) off the ground.
By the early 1960s, American high schools were following the lead of the colleges in acquiring foam rubber landing pits.
With the new, softer, elevated landing surface, Fosbury was able to land safely.

Fosbury did, however, compress a couple of vertebrae in the mid-1960s because not all high schools felt they could afford the new foam material.
 Fosbury recovered from this injury.

Fosbury's coaches at first encouraged him to continue practicing the straddle method, but abandoned that when his marks continued to improve.
In his junior year, he broke his high school record with a 6 ft 3 in (1.91 m) jump, and the next year took second place in the state with a 6 ft 5.5 in (1.969 m) jump.

The technique gained the name the "Fosbury Flop" when in 1964 the Medford Mail-Tribune ran a photo captioned "Fosbury Flops Over Bar," while in an accompanying article a reporter wrote that he looked like "a fish flopping in a boat."
Others were even less kind, with one newspaper captioning Fosbury's photograph, "World's Laziest High Jumper".
