We all wear the logos and do the workouts. But how often do we stop to ask where the names actually came from? Behind nearly every fitness brand is a moment of inspiration, a family blow up, or a name stitched together so awkwardly it sounds like alcohol was involved.
Some sound like slick marketing inventions cooked up in a boardroom. Others were pure accidents, personal feuds, or phrases dragged out of ancient languages and somehow turned into billion dollar businesses. Once you know the stories, you start seeing these brands very differently. Fair warning, a few of them might even put you off wearing the logo again. So here’s where some of the biggest names in fitness actually came from and why they stuck.
Adidas/Puma
Adidas isn’t a word. It’s a name. The brand comes from its founder Adolf Dassler. Everyone called him Adi. Combine Adi and Das and you get Adidas.
The story gets better. Adi’s brother Rudolf had a falling out with him after World War II. Rudolf left, started his own company and named it Puma after the cat. Two global sportswear giants born from one family argument in a small German town of Herzogenaurach in Bavaria, still the home to the HQs of both global brands. Every time you pick Adidas or Puma, you’re unknowingly choosing sides in a brotherly feud that never really ended.
Reebok
Reebok comes from the Afrikaans word rhebok, a type of African antelope known for speed and agility (below). The founders, Brothers Joe and Jeff Foster, wanted a name that implied quickness and movement rather than brute force. That’s why Reebok’s early branding focused heavily on running and aerobics before it ever leaned into strength training.
ASICS
ASICS is an acronym pulled straight from Latin. Anima Sana In Corpore Sano means “A sound mind in a sound body.” It’s one of the rare fitness brands whose name actually reflects a philosophy rather than a product. The idea was that physical training supports mental health and discipline, not just appearance. Quietly one of the smartest brand names in sport.
HYROX
HYROX was founded in 2017 by Christian Toetzke and Moritz Fürste, with the name originating as a portmanteau of “hybrid” and “rockstar”. Yes, seriously. It was created to represent a “hybrid” competition (combining running with functional, station-based fitness) and to make participants feel like a “rockstar”. No wonder these people cop so much shit.
Nike
Nike is named after the Greek goddess of victory. The famous swoosh is not just a tick. It represents the wing of the goddess as she moved at speed. The logo was designed by a Carolyn Davidson, university student in 1971 and she was paid just $35 for it. The brand itself was chosen because it symbolised winning. Simple idea. Perfect execution. Nike didn’t sell shoes. It sold victory.
Under Armour
Under Armour was originally meant to be spelled Under Armor, the American spelling The problem was the domain name was already taken. So they added the U, the English spelling. That small spelling change gave the brand a wider appeal look and helped it stand out globally.
It started with sweat wicking compression shirts for American football players who were sick of heavy cotton gear. Function first. Branding second. The name followed the attitude.
Gymshark
Gymshark was founded by a teenager in the UK. The name came from the idea that sharks must keep moving or they die. The message was obvious. Keep training. Keep progressing. Stop and you fade. It’s simple, slightly dramatic and perfect for social media culture. Gymshark didn’t grow through retail. It grew through identity.
CrossFit
CrossFit isn’t a workout. It’s a name built around the idea of crossing training styles. Greg Glassman used the term to describe fitness that sat at the intersection of multiple disciplines. Athletes did weightlifting crossed with gymnastics. Strength crossed with endurance. Barbell work crossed with running, rowing and bodyweight movements. Instead of training in a single lane, the method deliberately crossed them. Hence CrossFit.
F45 Training
F45 stands for 45 minute functional training. That’s it. No mythology. No ancient language. And somehow it became one of the most successful fitness franchises on the planet. Proof that clarity often beats creativity. You know exactly what you’re walking into before you walk in.
Les Mills
Les Mills was a real person. He was an Olympic athlete from New Zealand who opened a gym in Auckland. His family turned his training philosophy into a global group fitness empire. BodyPump. BodyCombat. RPM. These programs weren’t accidents. They were engineered systems designed to scale motivation across thousands of gyms worldwide.
