Testimonials
Leah Kuzmicz2025-01-30Trustindex verifies that the original source of the review is Google. 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! Berkley Cameron2025-01-20Trustindex verifies that the original source of the review is Google. 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! Sue Cypher2025-01-18Trustindex verifies that the original source of the review is Google. I love everything about this gym! Donna can work with any fitness level…she definitely pushes us but also helps modify when needed. The people we work out with are fun, encouraging and enjoyable to be around! This is a gym to feel at home at❤️ Come join us for a class…you won’t regret it! Kristin Brafford2025-01-17Trustindex verifies that the original source of the review is Google.

She truly makes each session feel personalized, offering adjustments and modifications to ensure everyone gets the most out of their workout. Her enthusiasm is contagious, and you can tell she genuinely cares about helping people reach their fitness goals. Whether you're a beginner or more experienced, Donna tailors the workouts to challenge and motivate you at your own level. I love seeing my gym friends who become family at CZ Fitness Lab.

I tried my first class three weeks ago and I was instantly hooked! The classes are challenging, Donna holds you accountable, and the members are welcoming. The workouts are all planned and you just have to show up. Give it a try. You won’t regret it! Nancy Ryan2025-01-02Trustindex verifies that the original source of the review is Google. Love this gym! Great workouts that are never the same and the coaches work with your skill level and provide modifications if needed. Jen Knudten2024-12-26Trustindex verifies that the original source of the review is Google. 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!

Workouts are challenging but scalable, ensuring all fitness levels feel included. The focus on functional fitness is fantastic, helping with everyday strength and endurance. The sense of camaraderie here is unmatched. Everyone, from the trainers to fellow members, are warm and encouraging. Impeccably clean, organized, and well-equipped. Danielle Ritchey2024-12-13Trustindex verifies that the original source of the review is Google. I looked at other gyms in Libertyville before CZ Fitness lab and let me say the comparison was clear. I feel a sense of welcome, community, and constant productive struggle. You will end up laughing at every workout while also constantly feeling challenged and returning for more. This is a great gym! Laurie Westphal2024-12-13Trustindex verifies that the original source of the review is Google. Fun and supportive coaching by Donna! Each and every workout is designed to foster all of your fitness goals. If modifications are needed Donna is there to make your workout successful! If you are looking for a change come join us!
