Great moves, song and especially filming, made in one take it seems, nice contre-jour there and amazing “gliding” dance near the end.
Some more details:
“Post hip-hop troubadour RJD2 teamed with dance and media artist Bill Shannon for the ‘Work It Out’ video. Shannon, born with a degenerative hip condition, developed a way to express himself through dance (and even skateboarding) on crutches. Director Joey Garfield took to the streets of New York and captured one continuous shot of Shannon, injecting RJD2 into random roles throughout the video.” (from Spinner, via Motionographer)
