I started working with Cassye at 43fitness about five (5) months ago. While I wasn't necessarily looking to meet with her in-gym, I was really needing a coach, who could help guide me in my journey for weight loss and better overall health. I worked with her remotely each week, as she provided insight into better workout options for me, based on my goals and available home gym equipment, and more importantly, help me better understand the types of foods that were holding me back from weight loss, and more so, those foods that would help me move towards my goals.

Within those 5 months, I have lost in excess of 30 lbs, and more importantly, have a far better grasp of my overall daily calorie, carb, protein, and fiber needs. Cassye is a great listener, who focuses on what someone's real challenges are, before jumping in with suggestions to "fix" the issues. I would highly recommend 43fitness to anyone that is really looking for a lifestyle change, and not just looking for the latest-and-greatest way to lose weight fast.

I started training with Cassye in July of 2021, and can’t recommend her enough! All of my apprehension about working out vanished after our first session!

Cassye is very knowledgeable and professional, but above all of that, she knows how to push you to be your best self in a positive, encouraging way. Cassye starts each session by asking how you are feeling, both physically and mentally, and adjusts the workout plan accordingly. Each workout has been challenging, yet doable, and has pushed me to make consistent improvements in my strength and abilities.

The mental and emotional benefits are endless, but the biggest physical change I’ve noticed is a reduction in my chronic back pain. Prior to working with Cassye, I experienced multiple trips to the hospital for recurring back spasms, and was always dreading the next time it would happen. Fortunately, I haven’t had any episodes since we started, and I am so encouraged by that. Not only has my core strength improved, but I have also learned new ways to almost immediately relieve my back pain when it tries to creep up on me.

If you are considering reaching out to Cassye to start a training and/or nutrition program, do it! She is amazing, and will have you looking forward to each session and feeling mentally and physically fantastic every time you complete a workout! Cassye has become a regular part of my routine, and I can honestly say I consider her to be a good friend at this point. I just signed up for another 6 months of sessions, and I can’t wait to see how much more progress I will make during that time!

Working with Cassye was fantastic! She gave me the consistent encouragement and inspiring energy that I needed and I was completely comfortable and unintimidated. I really appreciated and needed the form checks and reminders along with food choices. She is easy to talk to, answers any & all questions and explains things in a way I can understand.

I went in pretty out of shape with knee, hip and back problems. She was able to help me "re-boot" with simple super effective exercises that I will forever use in my new weekly routine at home. I'm stronger than I have been in years! Thank you Cassye for giving me the positive reinforcement, accountability and tools I so needed to get back on track with life!

I have been working out with Cassye for 6+ months. She is knowledgeable, kind & tailors my workout according to my specific needs. I met my first goal which was to become strong in order to lead the best life possible. I am now...so strong and powerful thanks to my workouts with Cassye! My next goal is weight loss. I have already lost weight, but am focusing on eating healthier based on Cassye’s recommendations.. My time with Cassye has been so beneficial to my health and well-being. I look forward to working with her in the future!

I have been working with Cassye for almost a year now and it has been a great experience! I came to her after a stress fracture in my foot and after restrictions were lifted during the pandemic. I was out of shape to say the least. Cassye creates an extremely comfortable environment, free of intimidation and really listens to you and your body. She takes the time to learn about you and creates workouts that fit your needs. She's a 10/10!

My experience with Cassye at 43Fitness has been truly transformational and educational. Working with her has completely abolished my fear of the gym!
Although she is highly skilled in working with all levels, I was searching for a trainer who was right for my initially limited skillset. Working with Cassye for over 6 months exceeded my expectation by a long shot.

If you’re considering a trainer in the Fort Collins area, I highly suggest meeting with Cassye for an initial consultation. She will work with you on your goals (or help you set some!) and provide you the tools you need to conquer them, and sustain your progress, even long after you’re done working together. This is not a one-size-fits-all trainer, this is high-quality, customized, coaching. Cassye is an incredible trainer, with a true passion of holistic nutrition, with bountiful health and exercise knowledge she loves to share with clients.

I worked with Cassye for a little over a year. She spends some time getting to know you and your body, particularly if you’re dealing with old injuries or a long workout layoff. I had both and she was able to get me back in good shape and confident enough to work on my own again. Not working out after a major shoulder surgery, and an old hip injury and subsequent replacement had really set me back. Cassye’s emphasis on core strength and then general fitness really helped me. I’d recommend her to newbies as well as she has an excellent knowledge of physiology and exercise science. She will push you…

I am so pleased and happy to say that I lost 13 pounds on the program with Cassye. I am honestly so thrilled the way she set up my plan, and I've been telling everyone I know about it. I am so excited with my new way of living, I am all about showing people this great new way that isn't dieting anymore!

I've come up with so many new recipes that are whole foods and I absolutely love what I get to eat. She changed my whole outlook on "dieting". I feel like I don't diet and this is just a great new way of life for me now. I am so excited to keep going forward especially now that I see results. It was a long time coming but I am so much more satisfied with the process long term.

I'd like to thank Cassye for all she's taught me and how supportive she's been. Thank you for not only helping me change for the better physically but also mentally getting my mindset to always feel accomplished and happy with myself in every little change towards the better. That really is what keeps me going is having that changed mindset!

Simply calling Cassye a trainer almost diminishes all the other things she is to me - personal trainer, nutrition coach, accountability partner, therapist and friend.

I was on this crazy roller coaster of balancing work with the rest of my life, especially in terms of healthy eating. She is along for that ride and always assuring me that "I got this" and to "get comfortable hitting the restart button." Her honesty and compassion help me turn away from feeling like a failure to actually having solid days at work and fueling my body with what it needs to succeed.

I'm so thankful to be on this journey with her and I'm pumped to see what I can accomplish with her helping me crush my goals.

Cassye is an incredible trainer. My time with her was absolutely transformational. I needed to lose some weight but more importantly, I needed to get in shape and learn how to create a healthy lifestyle that was sustainable and not overwhelming. I started with a 6 week challenge with another organization and lost the weight but knew immediately after completion that I was still nowhere near my goal. I hired Cassye and spent several months with her and she taught me everything from weight training to nutrition to health management. She has a wealth of knowledge and comprehension of overall fitness. She is not a one size fits all but rather she learned my specific needs and customized my training accordingly. I would recommend her to anyone who is serious about changing your health and fitness for life.

I am, at heart, a sea slug and slacker, and Cassye Delphy's training is helping me counter that. She provides good value, is very professional, and I enjoy the time I spend with her (even if exercise itself isn't my idea of fun). I highly value the exercise facility we use because it's quiet and pleasant. I appreciate Cassye's flexibility and knowledge of different ways to achieve the ultimate goal, from individual muscle groups to overall fitness improvements. I also appreciate the variety she brings to our sessions. She provides the right amount of positive attitude and encouragement for me, and the progress tracking is excellent.

I highly recommend 43fitness. Cassye is an amazing trainer. I have trained with her multiple times per week for a year and a half. I am 56 years old and had never lifted weights before but now I am hooked. I love going to the gym and each time I want to lift heavier/more than the last time. Cassye has taught me proper form in order to avoid injury and to work the proper muscles and she has been very patient teaching ME to be patient with my progress. Having her there to keep me accountable and disciplined in my workouts and food choices works well for me.
