My Mission

The mission of Cassie Gruber Fitness is to help others create a healthy lifestyle through fitness and nutrition.  I want to provide quality service and care for my clientele to help them create a sustainable lifestyle.  Fitness should be fun and it should be something you WANT to do on a weekly basis to make you happier and healthier.  I believe that everyone deserves to live a good life and that health and fitness is at the core.  Sometimes going to the gym or knowing what to do to achieve your desired results is confusing and mentally is a lot of work – so it tends to not happen or scare you.  It’s my goal to make fitness fit your level and to make it easy and fun!


My name is Cassie Gruber.  I grew up in a small town, Melrose, MN.  I am a grocer’s daughter and my daycare provider lived on a farm.  I was the 3rd child of 4.  I was an active kid and in plenty of sports!  As time went on I entered into high school and of course all the typical teenager awkwardness poured out of me.  Braces, curls, bangs, XXX jeans, overweight (hey I loved my ice cream!) and a tom-boy on top of it.  I was a pretty independent person and at times this was a struggle.  I did everything I could to try and fit in, trying new styles (punk stage anyone?), new make-up, new hair, a new diet… etc.  Since I was overweight, awkward, and a tom-boy, I just wanted to feel beautiful.  I wanted to feel like those girls in the fitness magazines I would see at my dad’s store.  I became highly aware of what I was eating and as time went on, almost stopped eating all together.  I was made fun of for being anorexic and bullied for anything I wore, looked like, or the way I was simply walking.  

Once I went to college, I yo-yo’d with my weight, and the time felt like an emotional roller coaster.  I felt inadequate and put on a tough face.  I had a great life and had some really good friends, but inside I was lost and it made me feel sad and alone.  Exercise was the only way to help me release stress and anxiety.

I realized after a while I was missing the things that made me feel fulfilled.  First, I was missing God.  I forgot about how important it is to connect energy and soul.  Second, I was missing a healthy diet and not nourishing my body correctly, not realizing how much your diet truly affects your life.  Third, I wasn’t exercising properly.  I performed endless hours of cardio and wasn’t seeing results I wanted.

It wasn’t until I decided to make real change in myself that I truly discovered who I wanted to be.  It was a battle and it wasn’t easy.  I started going to church again, really listening to the message.  I found a nutritional system that gave me energy, helped to balance my mentality and mood, and found a better way to exercise where I felt great from the inside out. 

Since then, my whole life has been centered on constant personal development and self-improvement.  Once I allowed to find my inner connection with myself and God, take control of my circumstance instead of self-pitying, I truly became the writer of my destiny.  I have forgiven myself for the down times and decided to love myself for exactly who I am.  It’s a work in progress, but nothing feels as good as self-love!  I’ve definitely had some epic fails and oh-crap moments, to say the least!  But I will never stop trying to be a better person.  I am eternally grateful for where I have been led to.  The fire has been lit under my butt for my dreams to become reality, empowering myself and others, finding like-minded friends, and living out an epic life that I am in charge of!

Do you struggle to get it together with your health?  Do you struggle to stay consistent with a plan long enough to see results?  Do you struggle in general with knowing how to lose body fat and keep it off?  Do you struggle with eating and find that dieting doesn’t work?  

Do you ever tell yourself, “I will never have a body like that.”?  “I will never be where I want with my body.”  “Who am I to think I could ever achieve that?” “I can’t do it.” “Why can’t I control myself and put down the dang cookie!?”  These are things I said so myself over and over even when I didn’t realize I was doing it.  But who I am to treat myself like that?  Who am I to think that I can put myself down when I have a TON to give to others?! The only way to learn is to make mistakes, and do trial and error.  Problems and struggles arise so that we can learn new skills, take new paths, and discover the person we are meant to be.  It’s never a “find yourself” journey but a “discover who I am now” journey.  We are to LOVE and that means loving YOURSELF also - no matter where you are at.
