Women change their lives for good

This is where
Real Change begins

My overall experience with SWK has been so empowering!! In 8 weeks I was able to reclaim ME again, prioritize working out again, and say to the world - I AM important! Thank you Kat!!
- Client
I was stuck in a rut and I found Kats program to be approachable and full of helpful knowledge both with nutrition and exercise training. Before working with her I would avoid the weights at the gym, and now I realize how much weight training can help overall fitness goals.
- Client
Kat has cultivated an amazing community of strong women looking to elevate themselves. I was very motivated by everyone and had the resources and support to be successful. Doing the online coaching with Kat is FUN. I made new friends and learned so many tools I’ll apply for life!!
- Client
Kat is more than a coach. She has been that form of light and enlightenment that I was looking for not just physically, but mentally as well. She is also on your side and wants you to succeed and is there with you every step of the way.
- Client
Love it! It has really taught me a lot about my body and also my potential. I was always afraid to take classes cause I’ve already classified myself as a physically weak person and was shy about working out in public. The community that she has set up, together with the personalized work out has given me the confidence to start working out and keep my routine .
- Client
It has been an incredible journey filled with physical and mental growth. I have learned that I am so much stronger than I thought. The support that Kat provides is invaluable. I also love the community of supportive individuals who have truly helped to lift me up during this journey.
- Client
My experience with Kat has overall exceeded my expectation. Kat has not only helped me transform physically but mentally. Having her support (and the SweatWithKat team) during my entire journey has helped me reach my health and well-being goals.
- Client
I've been working with Kat since August. My journey has truly been amazing. I had only a small hope that I would see changes when I first contacted Kat. Not only have I seen changes, I've loved the workouts and the diet (for the most part!) Most recently, I've been trying to better learn how different types of foods positively and negatively affect my body.
- Client
I know I've said this before but I am so grateful for everything you and your online coaching has taught me and I honestly am in such a better place mentally and physically now I can honestly say I am sincerely happy! I love you and thank you for EVERYTHING!! I am blown tf away by the pictures and I can't even wrap my brain around it!!!
- Client
I've been reflecting on my journey over the last 3 months and this is the first time I've been able to maintain or change my body goals without killing myself in the gym or feel like I'm starving or cutting out everything in my diet... I feel like I have a healthier relationship with food and working out, which overall is giving me a positive healthier mindset.
- Client
You are amazing. Thank you for wanting to support and help women change their lives for the better in all mind, body and soul! You are such a beautiful person inside and out, and we are so lucky to have you in this world making it that much more better and kinder and more beautiful!

WEEKLY CHECK INS

Each week, we’ll go beyond just the scale. We’ll reflect on your progress through photos, measurements, and more importantly—your energy, mindset, sleep, alcohol intake, cravings, and strength. These check-ins are our time to get real, celebrate wins, and course-correct if needed. Because this isn’t about perfection—it’s about building lasting, sober, and sustainable progress from the inside out.

Consistent Communication

You won’t have to go through this alone. You’ll have direct access to me—your sober-fit coach—so you can check in, ask questions, or get support whenever you need it. Whether it’s a tough craving, a mindset block, or a win you’re proud of, I’m here for all of it. Because real change happens in the moments in between the check-ins, too.

CUSTOMIZED MEAL PLAN

Cookie-cutter plans won’t cut it—especially when we’re working on lasting change. That’s why I take the time to truly understand you—your lifestyle, relationship with food, cravings, and patterns tied to alcohol or emotional eating. Together, we’ll build a flexible, realistic nutrition plan that supports both your sobriety and your goals, while helping you create a healthier connection with food for life.

Customized Home or Gym Workout Plan

Through my program you will learn the most effective way to workout your body, feel physically challenged and empowered, change your body composition, increase your confidence in the gym and love your body from the inside out.

Private Women’s Group Chat, Accountability & Support

This is one of the most powerful parts of the program. Inside our private group chat, you’ll connect with a community of like-minded women who get it. We share goals, celebrate wins, and support each other through the highs and lows of the sober-fit journey. It’s a space for motivation, accountability, and real connection—because healing hits different when you don’t have to do it alone.

Head Coach

Kathryn

I’m Kathryn Sauser—over 5 years sober, a fitness, nutrition, and mental health coach with more than a decade of experience. I’ve helped thousands of women transform their bodies, but it wasn’t until I got sober in 2020 that everything truly changed for me.

I created SoberFitGirl because it was everything I needed and couldn’t find. Alcohol was the one thing holding me back from the life I truly wanted. I was stuck in the cycle—drink, work out hard, feel shame, repeat. When I finally broke free, I built a life beyond my wildest dreams—and now I help other women do the same.

assistant coach

Ewa

With over 3 years of sobriety, I can confidently say that giving up alcohol was the most powerful decision I’ve ever made. I’ve always been passionate about fitness, but alcohol kept me trapped in a cycle of yo-yo dieting, binge eating, and burnout. It was the one thing standing between me and the life I truly wanted. Joining SoberFitGirl changed everything. This program gave me the tools, support, and accountability I needed to finally feel strong—in both mind and body. I lost 30 pounds, built a consistent fitness routine, and transformed my relationship with myself.

Now, I get to help other women do the same. I’m so passionate about coaching because I know how life-changing this journey can be. Every day, I’m grateful to walk alongside a community of women who are showing up, getting stronger, and rewriting their stories—just like I did.
