In the back row, Sarah, who usually hid during gym classes, found herself grinning. There was something about the bubbly production and Britney’s breathy vocals that made the mountain climbers feel less like a chore and more like a music video rehearsal.

Coach Maya stood at the front, wearing a Santa hat tilted at a defiant, pop-star angle. This wasn't your typical slow-burn yoga class; this was , where the goal was to burn off the gingerbread lattes while channeling 2000s energy.

The class moved in a wave of neon leggings and glittery sweatbands. During the bridge, where Britney pleads for her "only wish" to come true, the choreography shifted into high-intensity . Every time the chorus hit— "He's all I want, just for me" —the room erupted into a synchronized sequence of high-kick pivots and shimmy-shakes that worked the core and the spirit in equal measure.

The studio mirrors were already fogged with the heat of twenty bodies as the opening bells of Britney Spears’ chimed through the speakers.

As the final "Yeah, yeah" faded out, the class collapsed into a fit of breathless laughter, hearts racing and faces flushed. They hadn't just finished a workout; they’d captured a little bit of that early-aughts magic.
