It was released on January 4, 2019, by Atlantic Records as the lead single from her third and debut major-label studio album, Cuz I Love You.

[4] The single was written by Lizzo, Theron Thomas, Sam Sumser, Sean Small and Ricky Reed; the latter also handled the song's production.

Lollie King of Bustle wrote that the song "is sure to give you that much-needed confidence boost when you're feeling low.

"[14] Christian Hoard, writing for Rolling Stone, praised the song as the singer's "finest" single to date, and called it "a near-perfect retro-funk nugget that would have felt just right on a mirror-balled dance floor in 1982.

"[10] Joshua Bote, writing for NPR, stated that the song "continues [Lizzo's] winning streak of sing-songy, funk-heavy rap".

[11] Michael Roffman of Consequence of Sound wrote that the song "doubles as a jam and one of those dusty workout tapes you've got lying around your house.

The video, directed by Quinn Wilson, features the singer in an '80s-style workout program, late-night talk show, and selling products on an infomercial.

It features Lizzo with RuPaul's Drag Race alumni A'keria C. Davenport, Silky Nutmeg Ganache, Soju, Mayhem Miller, Asia O'Hara, Mariah Paris Balenciaga, Detox Icunt, Morgan McMichaels and Sonique.

[citation needed] On October 18, 2019, singer CeCe Peniston accused Lizzo of plagiarizing the song's "Yeah-yeah" ad-lib from her 1990s single "Finally".
