Thanks to her perpetually chill personality and laidback strut, you might think it hard to picture Yvonne beasting it out in the bike room. However, you only need to take one class to see that intensity and strength are actually second nature for her. Inspired by her diverse background as a ballerina, competitive cheerleader, and hip-hop dancer, Yvonne gets into character as a PERIGON instructor pretty seamlessly. Although she spends most of her days as an architect, houses aren’t the only thing she builds. Every class follows a thoughtfully-designed blueprint meant to provide a satisfying burn—and you’ll hardly even notice, since you’ll likely be climbing to the beat of a Kanye track or some catchy jazz fusion.
