Our History
In September 2010, Key Fitness's group exercise classes were added to the program offerings of Boltz's Family Martial Arts Academy. Boltz's has been serving the community for nearly 25 years in martial arts training, community seminars such as Women's Self Defense,  local police and community safety training as well as providing a safe, clean, wholesome space for kids and families to have fun together. Key Fitness classes were a HIT with our local families, a great addition to our offerings, and we have been rapidly expanding to accomadate our new guests from all across the Twin Cities to workout in a place where everyone knows your name!
Come in and check out our expansion and our brand new fitness floor!
