Two Experts.One ConnectedAdvantage.
Marketing strategy, education, and community-building for fitness pros and wellness brands.
DuoCore Solutions brings together award-winning marketing strategy, world-class fitness education, and a connected industry network to help coaches, brands, and wellness businesses grow with more clarity, stronger programming, and better execution.
Built for an Industry That Needs
More Than Generic Advice.
DuoCore Solutions was born out of a simple observation: the fitness industry has no shortage of talented professionals. What it lacks is a resource that speaks their language, understands their business, and can move the needle on both marketing strategy and education at the same time.
Marc Coronel and BJ Corey had been in each other’s orbit for years. Marc was building one of the most respected resumes in fitness education, and BJ was building marketing programs for global brands and category leaders. Both kept running into the same problem from different angles… fitness professionals and wellness brands needed a real partner, not a generalist agency or a one-trick educator.
In 2023, the conversations got serious. By 2024, DuoCore Solutions was live. The mission was straightforward… merge world-class marketing leadership with world-class fitness education and programming and give the industry a resource it actually deserved.
DuoCore is U.S.-based, globally connected, and built to help fitness professionals and wellness brands grow through sharper strategy, stronger education, and a more connected network. If you want to see how that work translates in the real world, read what clients and peers are saying.
