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.

💪Top 5 Misconceptions about Treadfit:1. 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. Our workout is individualized so that each client is working at an individual pace. 2. 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. 3. I hate running! No worries, our Strength class is perfect for you! In this forty-five minute class we focus solely on strength training. Strength training has been proven to build lean muscle, boost metabolism, and prevent injuries.4. 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!5. I need to get in shape before I try a class. Treadfit’s clients range from walkers to joggers to avid runners of all ages! We provide both modifications and challenges for each exercise to meet you where you are! Come try out a class! First class is FREE, link below: ... See MoreSee Less

  • 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 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’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!

    Treadfit is a great full body workout for anyone ! The class has options to meet you where you are in your fitness journey and it has options to push you towards your goals. 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!

    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.

    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

    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!

Lauren really does a fantastic job instructing us and she also pushes us to the next level! So glad I decided to take the plunge and try Treadfit Shorewood 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!
