Flexing (Bone Breaking / Bruk Up)
Also known as: FlexN, Flex Dance, Bone Breaking, Bruk Up
History & Cultural Context
Flexing is Brooklyn's contortionist street dance, and the one major New York street form whose musical parent is not hip-hop but Jamaican reggae and dancehall. It descends from bruk up, a Jamaican street style found in Brooklyn's dancehall and reggae clubs — Stefan 'Mr. Wiggles' Clemente described it as 'a reggae style of animation,' distinct from popping. The scene consolidated around Flex N Brooklyn, a talent show and local cable television programme started in 1992 out of Rocky and Sandra Cummings' home, and later around the borough's Battlefest battle circuit. Practitioners recognise roughly eight modes that dancers braid together: bone-breaking, the rhythmic disarticulation of joints; bruk up, simulating broken limbs; connecting or k'nect'n, tutting-like hand animation; get lo, floor-level work; grooving, the dancehall-derived rhythmic base; gliding, air-walking illusions; hat tricks; and pausing or pauzn, frame-by-frame stutter movement. Producers call the accompanying music Flex Dance Music, built on chopped riddims such as the 'Volume' riddim. Reggie 'Regg Roc' Gray became the form's chief organiser, and in March 2015 he and director Peter Sellars premiered FLEXN at the Park Avenue Armory with twenty-one dancers choreographing their own material.
Cultural Significance
Flexing belongs to Brooklyn's Caribbean-American communities and carries dancehall's social codes as much as hip-hop's. It has repeatedly been used as protest and testimony — the 2015 FLEXN production was made in the aftermath of the Michael Brown and Eric Garner decisions.
Characteristic Movement & Technique
Joints hyperextended and rotated past normal range in rhythm, arms and shoulders dislocating on beat, gliding footwork, hat tricks, and pauzn — movement broken into discrete frames as if the dancer were being scrubbed through video.
Partnering Dynamics
Solo in the ring, though flexers frequently stage two- and three-person narrative scenes — confrontations, arrests, deaths — that make the dance closer to physical theatre than to a display battle.
Competitive Context
Battlefest is the long-running Brooklyn battle circuit, with dancers judged on originality, storytelling and command of the eight modes. Reputation is also built through filmed street pieces and, since 2015, through theatrical productions.
Regional Variations
Bruk up in its Jamaican and older Brooklyn dancehall form remains distinct from the more theatrical, narrative FlexN developed in the battle and stage circuit; a heavier bone-breaking strand runs parallel to a gliding, animation-forward one.
Common Misconceptions
Flexing is not a subset of popping or animation, and it is not a hip-hop dance by descent — it comes from Jamaican bruk up and moves to reggae- and dancehall-derived Flex Dance Music. 'Bone breaking' also does not involve injury: it is trained joint hypermobility, not damage.
