“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!”

    “I tried Treadfit, expecting I wouldn’t enjoy it since I’m not a runner and have always preferred spin classes to running on a treadmill. However, I was wrong. I was hooked from my first class, and I have consistently attended Treadfit a few times a week for the past year. With each session, I feel…

    In the past, I’ve had a hard time sticking with a workout routine, but Treadfit is the perfect fit for me. I was nervous about the pace of class or that I would feel old there 😅 But it’s been such an awesome experience. I’m accountable to myself to show up, and once I’m there,…
