  • Personal Training


Phatty Nattie's group fitness was established in February of 2009. It started out with one instructor, owner, Natalie Knutson. She asked individuals to bring hand weights and a mat and meet her in the basement of an old Fergus Falls building. As success began to grow and word started to spread, business continued to boom. Just over three years later, an additional 5 instructors, Phatty Nattie's was approached by Lake Region Healthcare about a possible partnership. LRHC's goal is to make Fergus Falls one of the healthiest places in Minnesota. With a goal in mind and a large community of support a partnership was created. Spinning was the newest class brought on board after the partnership was made and has been a huge success to the Phatty Nattie's business. We now offer over 100 classes a week, all different times, levels and creativity.

As we continue to grow, we take pride in sticking with our roots. We focus on a comfortable, motivating environment. No one is judged, everyone is excepted! Our main goal is to make sure everyone there for their own reasons, but we are all there to work hard and achieve success!
