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.

❓How do you stay motivated to workout?👭Maybe you have the perfect accountability partner like Jessica Lynn and Allison Olivarez 💪These two both recently celebrated 1 year of Treadfit workouts due to their accountability, friendship, and our warm-welcoming environment!👏From Jessica: "Allison and I have been friends since college. A year ago she texted me that she was trying Treadfit. I decided to join her as we were both turning 40 last year. I am so thankful we took this leap together. It has been a year of 4:30am text messages “see you soon” Or “lets gooooooo” etc. Weekend text planning days we can go for the week even if it’s not on the same days. It’s been a year of Treadfit challenges completed together because of the accountability we have not only to Treadfit and our fitness goals but to one another. We both know as mothers how important this workout is first thing in the morning! I truly love working out with Allison and the rest of the Treadfit family regularly. I look forward to another year of early AM wake up texts, weekly accountability texts, and not to mention killer Treadfit workouts."👏From Allison: "It’s been one whole year of showing up for myself. One year of many 4:30 am wake ups. One year of @jboe23 sending me early morning texts because she values my journey just as much as her own. One year of singing our favorite college songs (and talking about the memories that go with them), laughing, and pushing ourselves. Wouldn’t have made it this last year without her, and I can’t wait to push ourselves even further over the next year!"💪👏We love your accountability to one another and the hard work you put into your workouts! Keep it up!👫👭So what are you waiting for? Grab that friend to be your accountability partner and sign up today!Claim your FREE trial here: ... See MoreSee Less

⬇️⬇️Top 4 Misconceptions about Treadfit:🚶‍♀️🏃‍♀️ I am not a runner. You do not have to be a runner to benefit from Treadfit’s unique workout. Walkers, joggers, and runners can benefit from the combination of cardio and strength training. The workout is individualized so that each client is working at an individual pace.🚶‍♂️🏃‍♂️ I run outside, not on a treadmill. Treadfit provides a challenging treadmill workout that incorporates bursts of speed and incline. Incorporating speed and inclines into your runs will improve your endurance, leg strength, calorie burn, and lung capacity.💪 I do not like to work out in front of other people. Treadfit’s fifty-minute workout is fast-paced, changing every thirty seconds to a minute. No one has time to focus on anyone but themselves!💪I need to get in shape before I try a class. Treadfit’s clients range from easy walkers to hard core runners. Let us help you get in shape!🆓️Come try out a class! FIRST WEEK IS FREE: ... See MoreSee Less

  • 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’ve never stuck to working out , I’ll do it a couple weeks and I’m over it! I’m over a month in and I’m addicted . I look forward to class and hate when I miss a day. Lauren is amazing. I feel so comfortable in her class. If you haven’t tried it you need too I promise you will love it ! 😁

    I love the class sizes and how classes are done. I don’t think in 25 classes, I have ever repeated the same workout. Exercises may be the same, but the instructors are sure to encourage you and keep you going throughout the entire workout. It is my favorite place to be when I want to workout.

  • 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.

  • 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 highly recommended anyone to try Treadfit and you can do it with a 7 day free pass! I have done CrossFit, gyms, classes etc and I finally feel like I found my fitness fit. Lauren and the instructors are very motivating and you can modify any classes to your fitness level. I equally love the strength and interval classes. Go ahead and try it…. You have nothing to loss and I know you will keep coming back!

    I’ve never been one to go to a “gym” to workout, but this is totally different. I love everything about it. Lauren is a fabulous instructor and keeps pushing you, which is exactly what I needed. Today was my first class and it most certainly won’t be my last, I cannot wait to come again!

I love the variety and the enthusiasm of the instructors. I look forward to my class time each week. Thanks to Lauren and Kailee for pushing me!

  • 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 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!

  • Took my first class at Treadfit Shorewood this morning and I will definitely be back! From the second I walked in everyone was so welcoming. The instructor was motivating and helpful. The class kicked my butt which is exactly what I need, and I was home before I would have even been up for work.

    First off it’s just a totally fun workout! Also it’s for all fitness levels since you go at your own pace and the instructor is super motivating and every time I go it’s different and a new challenge. The 50 minutes flies by and I really feel great afterwards. Love the small class size. Feels like you have your own personal trainer without the personal trainer price!
