The person behind the standard
GYM RHINO was designed by Shawn Swearingen — a U.S. Air Force Air Traffic Controller, certified personal trainer and nutritionist, FAA private pilot, Airframe & Powerplant (A&P) mechanic, and serial entrepreneur with no college degree. He has also competed in several NPC Men’s Physique competitions and in motorcycle road racing. For physique competition, he stepped onstage at a stage-lean 4–5% body fat — a level of discipline that separates the committed from the delusional.
Consistency under pressure. Those standards followed him into every business he built. At 24 Hour Fitness, he rose to General Manager and ranked #1 out of 74 General Managers in his division. But Shawn wanted to build something of his own.
He started Body Evolution Fitness Center as a personal training company and grew it into a full-blown fitness center: 13,000 square feet, 4,000 members, and a sale for more than $500,000. He built Blue Rhino Roofing from $0 into a million-dollar business. GYM RHINO is the next build — performance apparel designed from the inside of the training world, not a marketing meeting.
Designed in Houston, TX by a USA Military Veteran.
