Lauren is the owner of Treadfit Shorewood, a sports performance specialist, and an ACE certified Group Fitness Instructor.  She participated in sports growing up, but it was not until 2008 when she was diagnosed with Type 1 Diabetes that exercise became an important aspect of her daily life.  She started as a client at Treadfit Beverly and soon after became an instructor at both the Beverly and Frankfort locations. Lauren is a full-time teacher outside of Treadfit and truly enjoys helping others became the best versions of themselves.


Jenny, an ACE certified group instructor and nutrition specialist, is the founder of Treadfit. After completing five marathons and several half marathons, she began experimenting with shorter bursts of high intensity running mixed with strength training. She saw dramatic improvements in her fitness level, and decided to leave distance running behind. Jenny brings her love of running and fitness to the unique format of Treadfit’s workouts.


Kit has always had a love of fitness. In high school, she ran on the track team & in college, she began strength training. After having kids, she taught pre/postnatal Fit4Mom group fitness classes for 5 years & quickly found her biggest passion of helping people reach their fitness goals. Recently, she became an ACE certified personal trainer & is looking forward to inspire clients during their workouts.

Sara has always had a passion for both fitness and teaching. She recently decided to combine the two and received her ACE Group Fitness Instructor certification. After working out at home for years, she tried out Treadfit last winter and quickly fell in love with the classes and the atmosphere. Healthy living and fitness help Sara stay on her toes with her two little ones at home. Sara loves helping others meet their goals and feel good about themselves. She brings infectious energy and dedication to every class!

  • Lauren is the best instructor! I’ve only been working out at home for the past 2 1/2 years but she’s been pushing hard and motivating me in class! This is not like a normal gym where you are in a “fish bowl”(iykyk) I think that’s one of my FAVORITE parts is it’s smaller and you receive more one on one help with the instructor!! GO TRY A CLASS TODAY! You will not regret it!

    I have had a great time working out with Kit and Lauren. The five am classes are the best way to get your morning started!!!! Don’t be scared because it’s a treadmill workout. They focus on competing with yourself and not others. So whether you are an avid runner or just a walker Kit and Lauren can personalize the class for you and help you get stronger

    I have not worked out in probably 6 or 7 years and saw some mutual friends trying out treadfit… so I finally decided to try the 7 day free trial and fell in love! I love being able to schedule my workouts ahead of time! The times are great for my schedule. I have only had the pleasure of having class with Kit & Lauren and both of them are so welcoming and great! Lauren really pushes me to do my best & Kit is great helping me with form and making sure I’m doing everything correctly! All the ladies I have shared class with are wonderful & I love what a welcoming environment i feel walking in.. can’t wait to keep going!

  • I haven’t worked out in such a long time so walking in I was so nervous. From the start, walking in was not intimidating at all and Lauren made me feel comfortable immediately! The workouts are hard but Lauren and Kit are awesome and encourage you to push yourself while also doing what you are comfortable with. This was the perfect place to get back into my fitness journey!

    I haven’t worked out in years and was super nervous to walk in. From the start I felt welcome, encouraged, and part of a team! The workouts are hard, but Lauren and Kit are awesome motivators! And the playlists are pretty fantastic too! I now look forward to working out!

    I love the workout I get from Treadfit. I always burn at least 400 calories. It has a good mix of cardio and strength, and the timed circuits give you a great variety of moves. Lauren does a wonderful job of explaining exactly what to expect, along with encouraging you to always push yourself. Plus, I like the music she plays!

    I stepped out of my comfort zone and participated in a class yesterday. After 8 years of no working out, there were times during the workout I thought I may die lol. The Beauty of this work out is you are encouraged to go as hard as you can but reminded you know your limits. That was extremely helpful knowing no one was going to scream and yell because I wasn't moving fast enough. Today, it hurts to sit, my arms hurt lifting my purse and when I stand up I look I could be 90 yrs old 😀 I will be back. Highly pain, no gain.

    I love the environment at Treadfit Shorewood. It’s so welcoming and not competitive. The only person you compete with is yourself and I love how everyone can push themselves at their own pace. The trainers are encouraging and I love their energy. I’m so glad I found this place!

    The 50 minute class was wonderful, working both cardio and strength. Lauren's coaching was just what I needed, encouraging me to do my best, but not too pushy.

  • This place is awesome! It’s been a while since I have worked out, so I was pretty out of shape. I was able to tailor the class to my abilities and get a great workout. The instructors are so motivating and helpful. The classes are never the same which makes the time go by so fast. I can’t recommend Treadfit enough!!
