Here's what our clients are saying.

“Not only did I look and feel amazing on my wedding day, but I saw the connected benefits of better energy, better sleep, and fueling myself throughout the day. I lost almost 10 pounds and have kept it off even as life got busier, because I know the little habits I can stick to that make a difference.”

“I can’t believe the transformation I have made in 1 year. Both physical and mental. I’ve taken countless “before” photos of myself throughout the years, but never once took an “after” photo, until this year. This is the longest I’ve ever stuck with something like this, and it hasn’t been tedious or daunting.”

“In the six months I’ve been working with Back 40, I have lost nearly 40 pounds, increased my strength and relieved two lingering injuries to my foot and hip. In fact, I have registered for a marathon in May and have begun that training as part of my Back 40 regimen.”

“I wanted to change my habits and learn how to be healthier for the long haul. Kaitlin’s responses were so thorough, and she was great at pointing out my successes. I feel so much healthier and confident. It is actually fun to go shopping and try things on that magically fit, and I am able to run 3 miles and hike the dunes and feel great while I do it.”

“My experience with everything has been so positive. I have been working with them consistently for over a year now. The app is very helpful and user-friendly when it comes to what exercises you need to do and if you need to make any changes or updates. And the coaches are amazing!”

“The tracking made me realize I needed to up my protein, and it taught me that strength training is better than lots of cardio. The scale didn’t move much during these four months, however I lost several inches and I feel stronger, plus I’m more confident in the choices I make with nutrition.”

“What started as needing accountability turned into a complete mindset shift around balance and consistency. Kaitlin helped me build habits that actually fit my lifestyle, whether it was navigating social events, understanding macros, or improving my workouts. I feel stronger, more confident, and equipped to continue the progress on my own.”

“My experience with Back 40 Fitness has been nothing short of life-changing—it’s hands down the best investment I’ve made in my health and well-being. Through this journey, I’ve learned so much about food, tracking, and how to properly fuel my body.”

“I absolutely love the app, coaches and workouts (merch too!). I have never felt so supported. The app and plan have given me guidance and Sidney has really been such a light in my life.”

“My experience was 10/10! The intake was so thorough and felt like Sidney really took the time to get to know me, my body, my wants and needs. I had no idea that I was going to get so much more valuable coaching than just macros.”

“I wanted to start lifting but I didn't know where to start or how to write programming for myself. I also work a full time job with a rotating schedule and have two small children, so making appointments with a traditional trainer or committing to classes offered at certain times was not an option for me.”

“Sidney not only found great baseline numbers for me, but also taught me how to carb cycle for performance. Not only do I feel leaner, but I also had a half marathon PR during this process.”

“I love love love the B40 strong programming. It's progressive, I'm able to track my progress. There is enough variability that I don't get bored. I can easily sub out movements depending on which gym I'm at and what equipment I have available to me. Sidney is incredible and checks in with each workout and always has something positive to say.”
