Thanks for the 5-star review Todd! Glad you look forward to every session, even the ones with burpees!
Fantastic experience: I don't like Burpees. I will never like Burpees. But thanks to Greg and Nyree, the coaches, and the community at Grand River CrossFit, I can do Burpees. It's getting easier, and I'm getting better, stronger and healthier. Thanks guys!
Thanks for the great review Brent. We'll try to get you to the point of liking burpees, maybe.
Fantastic experience: I’ve been taking classes here for a little over 6 months and I have nothing but good things to say about the gym, the fantastic coaches, and the amazing people here. Fun workouts every week that keep you interested and can be modified to any fitness level. The community is incredible and very welcoming! I’ve seen so much progress already and I’ve never felt stronger. Come check out Grand River CrossFit. You won’t regret it!

Thanks for the amazing review Dan. We love having you as a part of our gym family.
Fantastic experience: I followed GRCF on social media for a long time before finally trying it out almost 2 years ago. I was “working out” at home during the pandemic and not really getting anywhere. The coaching and accountability (and friendly competition) of the CrossFit group classes has been a gamechanger. I am so much more motivated to show up and try my best. I thought as an introvert I might be uncomfortable in a class setting, and to be honest it did take a few months to really get used to, but the benefits outweighed any minor discomfort plus the coaches and other members are SO nice and friendly and encouraging. And because I’ve actually stuck with it, unlike other less fun programs, my health has improved *dramatically* in just a year or so of consistent attendance. Thanks Nyree & Greg! To anyone thinking about joining, do it now, don’t wait years like I did.
Thanks for the amazing review Amy. We are so glad we have made a great environment for you to be your best. We love having you in our classes.

Fantastic experience: 5 stars for Greg Segui. Excellent coach, good classes, open gym Saturdays, running workouts Sundays, workout parties, charity workouts. I am not sure what else people would need to get fit!
Thanks for the great review Nima. We are so happy you are loving classes and are a part of our CrossFit family.
Fantastic experience: I joined cross fit at Grand River in March of 2023. I had no idea what to expect - suffice to say I love it as I am still there - going 3 times a week! The coaches are passionate about what they do - they modify movements if you need it (like I do!) the age range of attendees is 18 - 80 and the support of fellow cross fitters is awesome! Highly recommend!!
Thanks for the great review Sharon. You are doing amazing in class. I am glad you wrote this review on non burpee week!
Fantastic experience: What an amazing group of coaches supporting, challenging and encouraging all fitness levels and ages. You really do become a part of a growing family where every workout can be maximized or modified to meet your ability. Join today! Your future self will thank you!
Thanks for the great review Kristie. You are doing amazing in class and we love having you as part of our CrossFit family!
Negative experience: They don’t have a drop-in policy, so for a new Dunville resident, where is the sense of community that CrossFit promotes?

Fantastic experience: Just finished my on ramp sessions at grand river crossfit. I am very impressed with this gym and its welcoming atmosphere. Was very nervous as i have never lifted weights before, but Yolanda was a great on ramp trainer!
Ainsley, we are so glad you felt welcome and had an awesome experience with Yolanda! We are excited to help you achieve your fitness goals. Thank you for choosing Grand River CrossFit to be part of this journey.
Fantastic experience: I’m Yvonne Struyk. Grand river crossFit is great. Fun, fast, and have seen results! What else do you need:)

Fantastic experience: This gym is my second home! The class structure still feels like you are working with a personal trainer. The owners are knowledgeable and supportive and they really cultivate a family-like atmosphere in their gym. It's a great place to crossfit!
Thanks for the review Jen! We love the energy of the class structure. It is so motivating and inspiring to see all fitness levels in the same class working hard and encouraging each other.
Fantastic experience: First off, I am 62 and I have been a member on and off for several years. Last year I once again made the commitment to join in July 2021 with a new mind set. I always thought I should keep up, something I put upon myself. This time it needed to be different and Greg and Nyree have helped, guided and pushed to make me stronger and more confident in myself. All the while keeping in mind my personal limitations. They go above and beyond to modified workouts as necessary to suit all the needs of their CrossFit members. It is truly a family community, in which we find encouragement to push ourselves a little harder and a little farther. Come join our CrossFit family and trust Greg and Nyree to help guide you to reach your fitness goals. And see how truly strong you are!
It has been a pleasure to watch you get stronger! We love your determination and perseverance. Adapting our program to suit individual needs allows everyone to get a great workout while respecting individual abilities. Thanks for the review!
Fantastic experience: Workouts adjusted to ability. All can do every workout
Fantastic experience: Grand River CrossFit is such an amazing, welcoming, fun place to belong to. After moving to Dunnville about a year and a half ago, my boyfriend and I didn’t have gym memberships anymore and explored the idea of CrossFit and met Greg and Nyree. We have had the pleasure of working with both of them during our 30 minute personal training sessions and they are truly the best. Nyree is now our coach on a weekly basis and she makes our workouts fun, different and challenging while always encourages us to do our best while lifting safely. We leave our sessions feeling stronger and even more excited for our next workout!
We have a blast working with you! It has been a pleasure to watch you both get stronger with each session. Thank you for making Grand River CrossFit a part of your fitness journey!
Fantastic experience: I was looking for a gym that could help motivate and push me to be a better version of myself after moving into the area and the physical ailments COVID-19 lockdowns had caused. Greg and Nyree have created a very friendly, community oriented gym that’s extremely capable of catering to anyones individual needs wether it’s their first time in a gym, recovering from an injury or life time gym enthusiast looking for a change in training style. Class times are convenient with availability throughout most of the day making the classes something to look forward to each day. I highly recommend this gym a try!
Our goal is to make your time at the gym the best hour of your day! From beginners to experienced athletes like you, we aim to make sure each workout is getting you one step closer to your goals. Thanks for the review!

Fantastic experience: Positive: Communication , Professionalism , Quality
Fantastic experience: I love the fact that I never have to plan my own work out or worry about knowing any of the movements because you will have all that planned for us. Your motivation and encouragement that i get from the other members and coaches have kept me going for the last 19 years as well as the always changing workouts so I never get bored.
Taking the guess work out of fitness is an important part of what we do. It makes it so much easier for you to focus on what you need to do. Thank you for being part of our gym family for nearly 20 years!

Thanks for the review, Val! Members like you are why we have a great atmosphere. Supporting each other both in and out of the gym is what builds a great community.
Fantastic experience: I have been a member of Grand River CrossFit now for 7 months. Walking into a new gym can be very intimidating but the coaches and fellow members make you feel like a part of the family immediately. The coaches are awesome and very professional and will help you by modifying the workout to your skill level, while still challenging you. I would recommend Grand River CrossFit to anyone considering joining a gym to get fit, healthy and have fun while doing it.
Thanks Michelle. We are amazed at the progress you've had. Thanks for sticking with us during the pandemic.
Fantastic experience: This place is like home to me, the most comfortable, genuine, relaxed atmosphere out there! I love not having to think about what my workout is going to be, I just have to step in the door and it’s there for me! I love the challenge that these coach’s push us to do within our limits! Everyone is so kind, along with helping each other out, and cheering each other on! Its like one big fitness family! Wouldn’t trade this gym for the world ❤️
