This energetic gym anthem is based on a snapchat message filmed by Lethal Bizzle in his Ferrari, in which he is seen fist-pumping in his car. The Grime artist overlaid the video with the words "Rari work out." He explained to The Sun: "I got on Snapchat, pumping my arm, pretending I was still in the gym and it caught on."
The song features guest verses from former member of the grime group Meridian Crew JME and East London Grime MC Tempa T.
