It was the height of the American jogging craze, a cultural phenomenon that swept through neighborhoods, parks, and city streets during the late 1970s. Millions of everyday citizens laced up their sneakers, lured by the promise of cardiovascular health, mental clarity, and an accessible way to keep fit. The movement was captured brilliantly by the zeitgeist when Jim Fixx published The Complete Book of Running in 1977, transforming a niche pastime into a national bestseller and a massive commercial wave. Even the highest levels of political power felt the shift; President Jimmy Carter famously caught the jogging bug, cementing the activity’s status as the ultimate modern exercise.
Amidst this sweeping cultural transformation, millions of ordinary joggers took to the pavement day after day, quietly pushing through minor discomforts and inconveniences in the pursuit of wellness. But for one of these runners, a simple routine workout would spark a brain wave that would ultimately produce a now-ubiquitous symbol of female athleticism and independence: the modern sports bra.
Lisa Lindahl had never been particularly athletic during her youth. In fact, she was the quintessential kid who would find any excuse to skip gym class, often hanging back with her best friend rather than participating in team sports or track events. However, working at the University of Vermont in 1977, she found herself swept up in the broader cultural momentum and decided to take up jogging as a way to lose weight. To her surprise, she discovered that running was deeply empowering, offering a sense of freedom and physical autonomy she had never experienced before.
Yet, this newfound passion came with an unexpected physical toll. During a phone call with her sister one day, Lindahl found herself venting and complaining about the severe discomfort of running with a traditional, everyday bra. The design was simply never meant for high-impact aerobic activity. Underwire dug painfully into her skin, causing chafing and bruises, while her breasts bounced with every stride, resulting in persistent physical pain. Listening to the frustrating predicament, her sister jokingly wondered aloud why someone hadn’t invented a jockstrap for women.
The casual remark struck a chord. Lindahl set out to solve the problem that millions of women had silently endured, turning a frustrating personal obstacle into an engineering and design challenge.
Realizing that she could not tackle the project alone, Lindahl recruited her friend Polly Smith. Smith was her erstwhile fellow gym class truant from their school days, but she had since carved out a professional path as a skilled costume designer. Recognizing that costume design required a deep understanding of textiles, movement, and body shaping, Smith quickly brought in Hinda Miller, another talented fellow designer. Together, the trio formed an informal collective and set out to develop a prototype that would meet the rigorous demands of female runners. They envisioned something revolutionary for the era: a garment that would be seamless, breathable, and capable of providing effective compression without the hardware of traditional undergarments.
Weeks of intense frustration followed as the trio experimented with various materials, cuts, and configurations. Designing a garment that could restrict vertical bounce while remaining comfortable enough for long-distance running proved remarkably difficult given the limitations of late-1970s athletic apparel.
In an effort to lighten the mood during a particularly frustrating design session, Lindahl’s then-husband pulled a men’s athletic jockstrap over his head and joked that he had successfully solved the design puzzle. That lighthearted moment provided the exact spark they needed. Looking at the athletic supporter, Smith experienced a sudden light bulb moment. Seizing the elastic bands and supportive pouch structure of the men’s undergarments, she began sewing two jockstraps together, manipulating the fabric to create a radically different configuration that hugged the female torso securely. Miraculously, it worked, serving as the first truly workable design for breast support during exercise.
Recognizing the immense commercial potential and societal need for their invention, Lindahl and Miller patented the design and co-founded Jogbra Inc. in 1979. To get the enterprise off the ground, Miller secured a modest $5,000 loan from her father, supplemented by additional early investor funding and essential manufacturing partners who were willing to take a chance on a completely new category of women’s apparel.
Operating out of early makeshift setups, the co-founders pitched their novel product directly to boutique athletic shops and trade shows. At the time, they figured the venture might simply operate as a modest side gig, filling a specific local need rather than launching a global industry. Yet, the overwhelming response from women eager to run in comfort quickly proved that the invention had tapped into an immense, unserved market, forever changing the landscape of women’s sports and activewear.
