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.

  • 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!

    This was such a fun class ! It’s hard and makes you push yourself but you’re not overdoing it because you’re in control of what makes you comfortable! Lauren is an awesome instructor too! She makes you push yourself to the best of your ability ! I can’t wait to take more classes ! Highly recommend !

  • 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’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 heard about Treadfit thru my run club. I like running but want to tone my body. so I did the 7 day trial and then bought the 10 class pass. I have tried the strength class and the treadfit class...I LOVE the treadfit get cardio and strength. you will walk away sore the first few classes...but it gets better....and it's a GOOD hurt!!! I like that the class is different everytime you go in!!

  • 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 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!

    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!!

    Absolutely LOVE every single class I have taken at Treadfit Shorewood. Each class is different and I always burn over 500 calories! Today alone I am at 716 calories burned! 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 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 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.

    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.

  • 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!

    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!
