Before taking classes with Gretchen I didn’t like exercising. I have now been going to 3-4 classes a week for a year and a half. It’s so fun to learn that I can do things I couldn’t believe I could possibly do. I give all the credit to Gretchen. She’s a great coach.

I work with Gretchen at Key Nutrition & Performance for my workout programming for use in the gym nearest me. I have worked with Gretchen for a couple years now and am always impressed with her consistent, logical programming. I feel stronger than ever and I look forward to every 8 week program. I truly feel like Gretchen looks out for her clients’ best interests. The workouts I do are primarily straightforward weightlifting with the occasional CrossFit-inspired WOD. The Metron app they use is super helpful in recording my workouts and provides explanatory videos for anything I’m unsure about. I would recommend Gretchen and Matt at KNP to anyone wanting to do things the right way when it comes to fitness and strength training.

First of all Gretchen and Matt are good people and genuinely have your best interest in mind. I have been going to the Vitality class for over a year now and have had considerable amount of change in body fat loss and muscle gain. The work outs are challenging and vary from day to day and from week to week. I’m surrounded by likeminded people and have developed friendships with the people in my class. If you’re interested in making a change to improve in your physical and mental health give Gretchen and Matt a try, you won’t be disappointed.

Gretchen was great - I'm stubborn and tough to train, but she knew all the right things to say to keep me from being my own barrier and help me achieve my goals. Thank you Gretchen!

If you want a gym with trainers that push you to do your best this is the gym for you. Gretchen and Matt are very passionate about fitness and working with you to get you into the best shape possible. I have some physical limitations but Gretchen worked hard to adapt the workouts for me. I’ve spent my adult life taking care of everyone but myself and I’m in the worst shape of my life but Gretchen has shown me I can do more than I thought possible. I definitely recommend this gym, and its owners and classes are top notch!

It's never too late to start your fitness journey. In September 2023, I started training at 69 with Grethen at KNP in the Vitality group. I was terrified, but they welcomed me with open arms! It has changed my life in more ways than one.
I look forward to my classes with her because she makes exercising fun and challenging. I highly recommend Matt and Gretchen at Key Nutrition& Performance, which is now located at Fiesta Plaza!

I took my first class at KNP about a year ago and loved it! The classes are both fun and challenging. Gretchen is kind and encouraging but also tough and helps you step out of your workout comfort zone. Gretchen is also very knowledgeable about what your nutrition should be for your individual goals whether that is weight loss or muscle gain. I highly recommend Key Nutrition and Performance!

Key Nutrition & Performance has helped me change my life in more ways than one. Matt and Gretchen are prime examples of what it takes to be a good coach. They have created a welcoming and encouraging atmosphere to the one thing most people are fearful of. If you are looking for a place to not only get fit but fit in then this is it because it doesn’t matter what level you’re starting out at you’re going to get the same level of support and respect that everyone else does. Top notch establishment and people!

Key Nutrition & Performance has changed my life. A year ago I couldn’t even get myself off the floor. I could barely walk without pain. Thanks to the Vitality classes & Gretchen Key’s guidance, I have great mobility, strength & endurance. KNP has been a blessing to my life.

I joined KNP Barn Classes 11 months ago and it is the best thing that I have ever done for myself! I work out with the Vitality Group and we work hard but we also have a lot of fun! I have made so many new friends and love every minute of what we do. I have always wanted to join a facility like this but was always intimidated and would have not know what to do as far as a workout. But Gretchen has guided me thru the last 11 months and it is so exciting to see and feel myself getting stronger and doing things that I never thought I would ever be able to do!! Gretchen and Matt Key are the best by far in my opinion and I am so happy and proud to see them open their new facility at Fiesta Plaza!! And all I have to do is show up and say Yes Coach!!

Gretchen has changed my life in so many ways! Not only do I see a change in my body composition, but I see a change in attitude! I’ve met some of the most wonderful people since joining the Barn classes over a year ago! I can’t say enough about Gretchen and what she does for each client, regardless of age or ability! 🥰

I still remember the first time I saw Gretchen at the gym exercising, she looked so unattainable to me, I always liked to watch her exercising because I felt a lot of admiration for her, one day she approached me and talked to me about her classes that she was starting and immediately I got in touch with her and started attending her classes, it is always a challenge and she tries to make u physically but more importantly mentally strong, there I met incredible people who are always very comforting to train with, I totally recommend her classes, she is very professional but she is also your friend. It is for all types of people and ages, my boys take classes with her and they love it, I recently had a baby and during my pregnancy I was training with her, my recovery after a C-section was faster than with my other children.
I am very happy for her and her husband for the new location they recently opened.❤️

One of the standout features of Key Nutrition & Performance is the personalized training programs. Gretchen and Matt take the time to understand your individual goals, whether it's weight loss, muscle gain, or improving overall fitness. They don’t take a one-size-fits-all approach; instead, they create tailored workout plans that evolve as you progress. The hands-on guidance ensures you're not just performing exercises, but doing them correctly and efficiently to avoid injury and maximize results. It’s a community, a family, and a place where personalized attention to health and fitness truly shines.

Highly recommend these two !! When I first started I was terrified but Gretchen made sure to welcome me with open arms. She continues to keep me motivated and works closely with me to make sure my workouts and nutritional goals are met! If I ever have any questions I am not afraid to ask. Gretchen is a great friend but even better coach! If it wasn’t for her I wouldn’t be where I am today!
