A Goodbye Gift That Changed Everything

In 2009, Cassey Ho was 22, teaching Pilates part-time at a studio in Southern California, and about to move across the country for a corporate job as a fashion buyer in Boston. She didn't want to leave her 40 students without workouts. So she filmed one Pilates video, uploaded it to YouTube, and told her class they could follow along after she left. That was the plan. One video. A nice goodbye. Then strangers started watching. The comments piled up—people asking for more workouts, requesting specific body parts, sharing their results. Cassey kept filming. She called the channel "Blogilates" and invented her own format: POP Pilates, which fused pop music with classical Pilates moves.

From Fashion Buyer to Full-Time Creator

The Boston job didn't go well. Cassey was miserable. "I was so miserable at work," she told Shopify in an interview. "I felt that this was a sign from the universe telling me 'you need to go all in on yourself.'" So she did. She moved back to California and went full-time on Blogilates. No safety net. No backup plan. Just a YouTube channel with a growing audience that loved her workouts. The growth was steady, then explosive. Blogilates became the #1 female fitness channel on YouTube. The numbers today: 7+ million YouTube subscribers, 3.7 million TikTok followers, 3+ million Instagram followers, and over 6 billion total video views across all platforms. What is POP Pilates? POP Pilates is a fitness format created by Cassey Ho that combines pop music with Pilates exercises. It's now the official Pilates format at all 24 Hour Fitness gyms in the United States, taught by certified instructors worldwide.

The Fashion Designer Who Was Told Not to Design

Here's the twist. Cassey didn't just want to be a fitness instructor. She wanted to be a fashion designer. Growing up as the daughter of Vietnamese immigrants, that dream was shut down early. Her family pushed her toward medicine. She studied Biology on a full-ride scholarship at Whittier College, far from the fashion world she actually wanted. But YouTube gave her a platform. And once she had an audience, she had something most aspiring designers don't: millions of potential customers who already trusted her taste. In 2016, she launched POPFLEX, an activewear brand designed for women who actually work out. Not athleisure for brunch. Functional workout clothes with real pockets, zero-camel-toe technology (she has patents on this), and designs that look good enough to wear outside the gym.

How POPFLEX Became an Inc. 5000 Company

POPFLEX didn't grow through paid ads. It grew through Cassey's content. Every workout video doubled as a product showcase. Cassey wore her own designs while filming, talked about the design process on social media, and brought her audience into every decision. She asked followers what they wanted. They told her. She made it. "It has to be like talking to a friend about something you just bought and love," she said. "Otherwise, people see right through you." The results:

Metric	Number
Sales Growth Since 2019	800%+
Inc. 5000 Status	Listed
Consecutive Years Doubling Sales	3
Monthly Website Visitors	1.5 million
Team Size	~30 people

And here's the part that gets interesting: a single POPFLEX product went viral when Taylor Swift wore it. In April 2024, Swift wore the patented Pirouette Skort in a YouTube Short. It sold out in 15 minutes.

The Target Deal That Doubled Everything

In January 2025, Cassey launched a second brand—Blogilates—exclusively at Target. This was a different play. POPFLEX sells premium activewear at premium prices through its own website. The Target line offers romantic, affordable activewear at $15-$40 price points, available in every Target store in America. Her team manufactured 1.1 million units. Half sold in less than a week. One video of Cassey standing in front of the Target display hit 40 million views across her social channels. Fans flooded stores, tried on pieces, and compared them to POPFLEX originals on TikTok. The fear was that a cheaper line would kill POPFLEX sales. The opposite happened. Popflex.com sales jumped 112% year-over-year after the Target launch. New customers found POPFLEX through Target and traded up.

The BODY by Blogilates App

Cassey didn't stop at physical products. She built BODY by Blogilates, a subscription fitness app that packages her workout content into structured programs.

What does the BODY by Blogilates app include?

The app offers hundreds of ad-free workout videos, monthly workout calendars, 30-day challenges like the "100 Ab Challenge," a 90 Day Journey tracker (goals, mood, food, sleep, energy), and a social community where users share progress and connect. App pricing:

Monthly: $3.99
All-Access Monthly: $6.99
Yearly: $39.99
Journey Yearly: $69.99
7-day free trial for new subscribers

The app holds a 4.7-star rating across 4,400+ reviews on the App Store. It's available on iOS and Android. The app matters because it's recurring revenue. YouTube ad rates change. Brand deals come and go. But a subscription app generates predictable income every month. At even a few hundred thousand subscribers, a fitness app at $3.99-$6.99/month adds up fast.

4 Lessons From Cassey Ho's Playbook

1. Start With What You Know, Scale With What They Want

Cassey started teaching Pilates because she loved it. She launched POPFLEX because her audience kept asking for better workout clothes. She built an app because they wanted structured programs. Every expansion was audience-driven, not ego-driven.

2. Your Content Is Your Marketing

POPFLEX spent zero on traditional advertising. Every workout video was a product demo. Every Instagram post was a showcase. When you build in public and share your process, your audience becomes your sales team. Other creators in the fitness space have done this too—Pamela Reif built her PAM app and Kayla Itsines sold Sweat for $400M using the same playbook.

3. Don't Pick Between Premium and Accessible—Do Both

The POPFLEX/Target split was smart. Premium products for core fans, affordable products for new customers. Each feeds the other. The Target launch didn't cannibalize POPFLEX. It grew the whole pie by 112%.

4. Own Everything You Can

Cassey owns POPFLEX (not a licensing deal—she designs every piece). She owns the Blogilates brand. She owns the app. She controls her YouTube channel. The Target deal is a partnership, but Cassey controls the creative. When you own the platform, you own the future. That's why 50K engaged followers beats 5M passive ones—it's not about reach, it's about control.
