The #1 female fitness channel on YouTube with POP Pilates workouts and POPFLEX activewear brand.
How Cassey acquired customers
Tools used to build Blogilates / POPFLEX
Cassey Ho posted one Pilates video for her 40 students before moving cross-country. It accidentally became the #1 female fitness channel on YouTube with 500M+ views.
"I actually didn't mean to!" That's how Cassey Ho describes the start of what would become a multi-million dollar fitness empire.
During college, Cassey started teaching Pilates. When she was moving from California to Boston in 2009, she posted a workout video on YouTube for her 40 students to follow while she was away. "It quickly caught fire, and people began requesting more videos!"
The magic began when Cassey started breaking the rules. Fusing pop music together with classical Pilates routines created something the industry had never seen before. Students craved her innovative choreography because it brought the fun back into working out. She called it POP Pilates®.
Today, Blogilates is the #1 female fitness channel on YouTube with over 500 million video views and 4 million subscribers. But Cassey didn't stop there.
Her audience asked for clothes and yoga mats, so she began dressing her community. POPFLEX, her performance activewear line, has become an eight-figure brand. When Taylor Swift wore a POPFLEX skort, it generated 16,000 preorders.
In a groundbreaking partnership, 24 Hour Fitness made POP Pilates® the official Pilates format of all their gyms in the United States, creating an internationally recognized instructor certification program.
