About REP

REP designs world-class, innovative gym equipment that is sold around the world, and we are now expanding into apparel, supplements, athletes, and events. REP was established in 2012 by two brothers who shared a deep passion for fitness. From our humble beginnings of selling bumper plates out of a small garage, REP has experienced remarkable growth, now occupying over 300,000+ square feet of office and distribution space in the USA and internationally. With a dedicated team of over 200+ fitness enthusiasts, our vision is to be the #1 Strength Brand in the World. Our commitment to innovation, customer service, and value sets us apart.

We believe in building a culture centered around fitness, so we specialize in outfitting home gyms, commercial gyms, and strength and conditioning facilities. Our dedication to excellence has been recognized multiple times when we were featured in the Inc. 5000 fastest growing private companies in 2018 and 2021 and then voted the best home strength product launch in 2022 by Garage Gym Experiment. Our team works out together, and we regularly invite fitness superstars to join us. We organize fun challenges to test our limits - and the limits of our equipment.

At REP, we continue to grow and bring new opportunities for those who want to be a part of a winning team. We firmly believe that being surrounded by like-minded individuals fuels creative energy and fosters a fun and collaborative work environment. This role is based in our state-of-the-art headquarters with a bright, spacious, shared workspace; scenic views of the Rocky Mountains; and a kitchen always stocked with healthy snacks, protein powder, and coffee. We offer a hybrid work environment with a minimum of three days in the office, but there’s flexibility about which days and hours.

Our Core Values

  • Think Like a Customer - We empathize with our customers; understand the 'why' behind every decision we make
  • Progress not Perfection - We don't let perfect get in the way of good; we are better today than we were yesterday
  • Positive Attitude - Be a glass half-full kind of person and remember to have fun
  • Teamwork without Ego - We put the team above ourselves; we only win together
  • Take Initiative - We drive momentum; if there is an opportunity to make us better, we want to hear it
