I can’t sing enough the praises of Donna and CZ Fitness. I’ve exercised, ran, and worked out nearly my whole life and this gym and these classes continue to challenge me. I genuinely look forward to class each and every morning. Donna does an amazing job of challenging everyone. You feel like you have a personal trainer amidst a group glass. To that end, everyone I’ve worked out with has been extremely nice and great to be with. It really is an amazing community at CZ Fitness.

If you’re unsure or can’t find the time, do yourself a favor and try a class. You will be welcomed by all in attendance and challenged along the way.

CZ Fitness has changed my life in the best way possible!! I was terrified to go back to a gym after 3 years of no exercise at all. From my very first class, Donna made me feel comfortable and let me work at my own level, while helping me progress over time and become the best version of myself. Everyone is so warm and welcoming and we have so much fun working out. It's been almost a year now and I feel like a new person. My day is no longer a good day unless I start it at CZ. Come join us!!! You will not regret it. :)

I can’t say enough good things about CZ Fitness! I need structured classes with a workout plan already made. The classes at CZ provide all of that. The strength classes are my favorite part- each class is packed with motivation, tailored intensity, and personal attention. Coach Donna provides a lot of energy, knowledge and genuine care for each of her members.
What sets CZ apart from other gyms that I have belonged to is the sense of community. The other members genuinely care and support each other. They help keep me accountable to my workouts.

I've been a member at CZ for three weeks now, and it's been a fantastic experience so far. The gym is always clean, with equipment well-maintained and readily available. I love that the workouts are always different...not boring! Donna L. is incredibly friendly and always willing to offer advice on exercises or help me with equipment. The group fitness classes are challenging and fun. It's a welcoming atmosphere that will hopefully help me achieve my fitness goals."

So thankful that we found CZ Fitness! A friend and I have been wanting to strength train and our at home dumb bell workouts weren’t cutting it. We both joined the lab after our first class. Donna has created an extremely approachable gym and it feels like you are being personally trained. She is very attentive to everyone’s ability levels, but most importantly creates a judge free zone and everyone is so supportive of one another!

I am a marathoner runner and started taking Donna’s group classes to improve my athletic performance. Everyone was so welcoming and it’s a judge free zone where everyone encourages each other. Donna motivates you brings out the best in you. The classes feel like personal training as Donna helps every single person ti make sure you have the right form and you push yourself to get better. You can go at your own pace and progress at your level. There are all ages in class and everyone is like a family. I have improved my marathon time and gained strength and a sense of community. You won’t be disappointed!

I need group fitness to stay motivated and consistent with exercise. CZ Fitness offers great classes within a gym community that is so friendly and supportive. No workout is the same, so you don't get bored or overtrain any one muscle group. It is not cross-fit (cross-fit is not for me), but you do get awesome strength training and improve your cardio fitness. Donna will meet you at your own fitness and strength levels either in group classes or personal training. She is also great at coaching youth speed and agility training to help middle/high schoolers achieve their fitness goals. The gym is always clean and has all the strength equipment you need to push yourself and get stronger. Kristy is an amazing Pilates instructor - she knows her stuff and cares about the well-being of all her clients. I love being a member at CZ fitness!

We are lucky to have multiple great gyms in town; but CZ Fitness is my current go-to! The community is from all walks of life and everyone can work at his/her own speed and weight without feeling intimidated or out-of-place. Donna provides a fun, relaxed atmosphere but still pushes you through a challenging workout everyday! Each class starts with stretching and mobility. She truly wants you to feel healthy and strong!
