Kara Peterson is the owner and trainer of GRIT Fitness LLC. She has been certified since 2012 and has worked with individuals of all ages and abilities, including kids, seniors and those in recovery from injuries and surgeries.

Often called "the GRIT garage or "the pain cave" GRIT Fitness is housed right on the owner's Oconomowoc property in a spacious detached garage. It's heated in the winter and open to 30 acres of farmland in summer, ensuring a unique gym experience that you won't find anywhere else.

Unlike other facilities in the area, GRIT Fitness is a small community of about 35 members. Training sessions are led by only one trainer, who is also the owner of the gym. Because of this, members know one another and have developed a special camaraderie through their fitness journeys.
GRIT Fitness is also super unique in that it has a very "outdoorsy" feel to it. It's situated on a 3-acre piece of land with views of 30 acres of farmland, giving it a peaceful vibe that can be important to those who don't love the feel of "big box" gyms.
Members love that their experience feels very personalized and that they don't have to worry about feeling self-conscious in a large setting. Everyone in the room at your session time will be meeting the same challenges as you.
