If you can't afford a gym membership, you can use your own city as a playground to get fit. That's certainly one of the reasons behind the world's growing Urban Movement, where people vault, climb, leap or somersault over walls, fences and other pieces of infrastructure.
Not just enjoyed by those who love Parkour, people who dance, do yoga or gymnastics are also getting involved, and American photographer Keith Reid is on a mission to document them.
The Tampa-based creative has a degree in Digital Audio Production, but has since developed as a photographer and digital artist, taking to the streets to find compelling stories to tell: "As a lifestyle photographer, I not only document the events around me, but also develop them into timeless pieces of art."
