About Us
Hot Ground Gym® (HGG) was founded in 2013 and is owned by military veterans and former first responders. We have developed a first-of-its-kind place for kids to be active and fit. We use an approach that combines obstacle course-based fitness and teambuilding challenges to provide a truly unique, wholesome, and super-fun experience to kids & teens.
The Libertyville location is the 4th HGG that was built and it opened in December of 2021. Hot Ground Gym® Libertyville is located inside the Canlan Sports Complex on the second floor. This was the first time an HGG was located inside a community recreational sports center. So far so good!

Assistant Instructors
Doug and Sam’s work would not be possible without a team of solid “assistant instructors”. These individuals are highly-motivated young adults that work closely with us during the day to help make magic happen. Most of this team has “aged out” of the HGG program. Some of them are preparing to become first responders, to serve in the military, to work in the trades or go off to college. We love mentoring our assistant instructors, and we greatly appreciate their help/work, and so do the kids.
