The person behind the standard
Shawn Swearingen was an air traffic controller in the United States Air Force. He is a certified personal trainer and nutritionist, an FAA private pilot, and an Airframe & Powerplant (A&P) mechanic — a serial entrepreneur with no college degree. He has also competed in several NPC Men’s Physique competitions, stepping onstage at a stage-lean 4–5% body fat — a level of discipline that separates the committed from the delusional.
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.
