“I am coming up on a year since starting Treadfit and it is one of the best decisions I have made for myself. I remember telling my sister-in-law I needed to get back into a health routine and she had recently started Treadfit. I was under the impression that it was a fitness home for runners, but it’s so much more than that. I enjoy the treadmill intervals mixed in with the weight lifting, the energy is contagious and the playlists are great! After my first free week, I was hooked. I love that every class is different and the instructors are motivating, they want nothing but for you to succeed. My mornings with Treadfit have given me so much more energy throughout my day, and I feel like a better Mom because of that. This is the healthiest and strongest I have ever felt and I encourage anyone that is looking for a fitness home to give Treadfit Lemont a try, you’ll meet some pretty amazing members too!”

    Since Covid hit I hadn’t been exercising on a regular basis. I was tired all the time, feeling physically fragile, and my balance was declining. I’ve been doing Treadfit consistently for two months and, it sounds so cliché, but I feel like a different person. I have so much more energy, feel strong, and my…

    “Treadfit was exactly what I needed. I have always worked out and have tried so many different things. Treadfit offers me a challenging class with the option to tailor it based on my needs for the day. Some days I am running  on the treadmill and some days my body says “we need to walk”….

    I’m thrilled to share my experience with Treadfit Lemont. I eagerly awaited the opening of the Lemont location, and from the very first class, I was hooked. While my favorite is the Strength class, I’ve also realized a significant improvement in my running with the traditional Treadfit classes. What truly sets Treadfit apart is their…
