Kris Gruner spent the first 25 years of his career in the commodity option trading business where he built and managed his firm's risk. Along the way, he trained and coached many young traders the art of risk taking. At the end of 2017, he decided to retire from the option trading business.

Having been a collegiate athlete and high school football coach for many years, Kris decided to join with a business partner, Chris Falcon, and create an entirely new business built around fitness and performance. Kris’s passion has always been teaching and coaching to help connect people and build relationships. That energy is now fully focused on building the WIN community. A community committed to a fitness experience that is better shared!
