Our Story
Body by MJ was created to give women a safe place to chase their fitness goals, meet like-minded women, and find a supportive community, all in one place. What started with a handful of women working out together in Chicago has grown into 3,800+ strong.
We partner with a wide range of trainers and studios to create a rotating lineup of events like: Pilates, HIIT, yoga, strength training, so there’s always something new to show up for.
