Fantastic experience: Just celebrated my 1 year anniversary being a member of CrossFit Groundworx. From the coaches to the members, Groundworx is more than a gym, it’s a close-knit community. The workouts are led by knowledgeable coaches who can help you tailor the movements to your specific needs. For anyone looking for a gym to feel comfortable in, Groundworx is for you!

Juan Pablo Santamaria 1 year ago

Fantastic experience: Groundworx was my second home for several years but I moved out of town in 2019. The times I’ve had the chance to come back, people and coaches are still so kind, welcoming, and it’s a great atmosphere. I love this place and miss this awesome community!

Fantastic experience: I was in town visiting for a month and came here for some classes with my sister who is a member. Everyone made me feel welcome and the coaches were really helpful. I had no prior CrossFit experience and I ended up learning a lot from them!

Groundworx CrossFit

Nicole Baranowski 1 year ago

Fantastic experience: I have nothing but the best things to say about this gym and community. I know how intimidating it can feel walking into a gym for the first time but all the coaches and members here are so welcoming that it doesn't feel scary at all.

B B 1 year ago

Fantastic experience: Groundworx is amazing. From the community to the coaches, everyone has your best interest. I have been attending classes over three years and my thoughts have never changed! They adapt all movements to your ability and make you feel confident and safe while lifting. Leaving a workout feeling accomplished and strong is an unbeatable feeling! This gym helped me through pregnancy and postpartum with classes and personal training to get me back on the floor. All of the trainers work with your body and abilities to make you feel comfortable. Having lots of injuries myself, and coming back from wrist surgery, I would recommend Connor and Marshall to help you get back into your grove. They take the time to understand your issues and work with you. Thank you Connor and Kate for continuously taking care of your clients and friends. You both run a fantastic business! Amazing trainers and even better community! Keep up the good work!

Svetlana Del Giudice 1 year ago

Fantastic experience: Great welcoming gym. Coaches are knowledgeable and supportive. Really for everyone who wants to keep up with everyday challenges or compete in higher levels.

And we’re happy to have you! We appreciate all of your support!

Jennifer MacDougall 1 year ago

Fantastic experience: Coming back to the gym post baby has been an amazing experience at CrossFit Groundworx. The coaches are knowledgeable and encouraging, and I always leave feeling accomplished. The community is next level, from day one I felt welcomed and I can’t imagine a better place to be. If you’re looking for fitness and friendship all in one place this is it.

Groundworx CrossFit

Michelle S 1 year ago

Fantastic experience: I've been to a lot of different gyms and Groundworx has been my favourite experience so far. The coaches are knowledgeable, attentive, and motivating, and the members are so lovely, fun, and welcoming. You'll feel a sense of community the moment you step through the door. I would highly recommend checking them out if you're looking to try crossfit for the first time or if you're looking for a new gym to go to. 10/10!

Wes MacDonald 1 year ago

Fantastic experience: Everything you could want in a gym. Fantastic programming run by a great group of people. Members are friendly and supportive.

Benjamin Hankins 1 year ago

Fantastic experience: Great gym with great equipment and a fantastic community. Been a member of CrossFit groundworx for over 5 years and can’t imagine going to another CrossFit gym. Everyone makes you feel welcome and the coaches are some of the best in the business

Cheryl Wetmore 3 years ago

Fantastic experience: One year ago the ownership of my favourite place changed. I didn’t know what to expect. I was hopeful I would continue to enjoy coming here. I was so happy that my expectations were greatly exceeded! Connor and his team have been great keeping us all motivated through these difficult times. The coaches are amazing and the members are all very supportive of each other! Give it a try!

Melissa MacDonald 3 years ago

Positive experience: They don't return calls.

Justin Cheong 3 years ago

Fantastic experience: Been a member for 3+ years and still happy to be here. The coaches and the community are great. Some of my favorite memories have come as a result of the friendships that I never knew I was going to make when I initially started. Lots of new equipment and new members are always welcomed. They even offer Physiotherapy and private training for those interested. Without sounding too cliche, I am grateful for Groundworx. It has really had a large impact on my life.

Brittany Brie D'Amico 3 years ago

Fantastic experience: I'm a huge fan of Groundworx gym. My husband used to teach there for years- and after it changed hands we couldn't stay away. I personally love going for the community. My job requires me to work from home, so waking up, getting out of my house and starting my mornings with the Groundworx crew has been a great start to my day. I've also noticed that there are so many different fitness levels. You don't have to "lift the most amount of weight" or do everything "at a fast pace".... it's so much more than that. Modifications are given when needed and the people who go to this gym are ALL different fitness levels. WHICH I LOVE. It makes me feel comfortable and nobody is looked down on.

Nicole Manning 3 years ago

Fantastic experience: I can't say enough good things about this place! Very knowledgeable, friendly and encouraging staff. Safe, clean and fun environment. Every workout can be modified for any ability level or to accomodate an injury. I love being part of such an amazing fitness community!

Michelle Sheridan 3 years ago

Fantastic experience: It’s a place where I feel comfortable to workout at my level of fitness. There is no judgment or any awkward feelings when working out. The classes are provided in a safe, professional and fun atmosphere. I love to come here and relieve any stressors that may have happened during the day.

Gayle Suderman 3 years ago

Fantastic experience: This crossfit box is truly for everyone. My husband and I are... older. The coaches are helping us to.focus on fitness... and that's our goal. "Crossfit" sounds scary to some... but honestly... this group is a sincerely, authentic and inspirational (and not at all intimidating) tribe of people. No matter where you are starting... you will feel fabulous (with maybe some well-earned sore muscles!) ...

Christina McKenzie 6 years ago

Fantastic experience: I really thought i would hate crossfit. But after a few classes, i found myself checking the night before and seeing what the next wod would be. Incredible coaches and staff. They encourage, push and challenge you, all while making you feel that you can actually accomplish the crazy thing they told you to do!! I love it here!

Muhyi Salih 6 years ago

Fantastic experience: I would really love to join and for sure will give it a try!!

Jenny Z 6 years ago

Fantastic experience: I went here for a free trial, and will 100% be going back! The coaches are super knowledgeable, friendly, and know exactly when you need a boost of encouragement. The other members are inspiring and motivational. I felt at home from day one. Clean facilities with all the equipment anyone could ever dream of. If you're considering trying crossfit, do it here!

John Demetris 7 years ago

Fernando Lopez 7 years ago

Fantastic experience: I was in town for a week, I'm so glad I found Groundworx for a few drop in classes. Friendly staff, great coaches and you can feel the community they have built up with their members. If I lived around here I'd be a permanent member for sure.

Tori Goes Outside 7 years ago

Melissa Parry 7 years ago

Fantastic experience: Great place with great staff!

Cat 8 years ago

Positive experience: Friendly staff. Saw my vice principal there... Motivating place of filled with people if many different shapes and sizes. I think it's good for if you want to get fit. Not the greatest if you are training for other sports. Not enough time allocated to teaching you proper technique before the timer starts. You can ask about it after, but I prefer to know before I do like 3 sets with bad form. .

Jessica Shifrin 8 years ago

Tony Broughton 8 years ago

Fantastic experience: Crossfit Ground Worx is a great atomosphe, I've been a member for the last 2 years. Finally have made a commitment to making time for my fitness even with a busy work schedule. Support, motivation, and achieving personal goals, keeps me coming back! I would recommend Groundworx to anyone of any fitness level, give it a try!

Dan Nicholson 8 years ago

Fantastic experience: Being new to CrossFit I didn't know what to expect when walking into Groundworx...but am so I glad I did it and have never looked back. That was 10 months ago and I can only reinforce what others have commented below. Globo gyms have never worked for me and I need to maximize my time when I do work out. I can truly say that in a 1 hour session at Groundworx I would never work as hard as that in a gym on my own. The coaches are extremely knowledgeable and will always make time to answer any questions you have. Take the courage to come in and try it out. The on ramp, sweat, Olympic lifting and CrossFit classes are all on offer.

Laura Hosier 8 years ago

Fantastic experience: Knowledgeable and professional coaches delivering quality programming in a great space. The coaches truly care about your development and go above and beyond to help you reach your goals. They offer an abundance of class times and open gym times, which is great for shift workers and those with hectic schedules. I am honoured to be a part of this amazing community and I love going to the gym every day.

Jody Mann 8 years ago

Fantastic experience: Groundworx is definitely my 'happy place' it is such a great community of people. Our coaches are so very knowledgable in many aspects of fitness and health and always take the time to answer questions. They also provide much encouragement to keep you going when you need it most. Crossfit and Groundworx have totally changed my outlook on exercising and I'm very thankful. Come try it out you won't regret it.

Chris Cambly 8 years ago

Fantastic experience: Groundworx provides positive vibes with a family atmosphere. Workouts are lead by knowledgeable, caring and supportive instructors that will scale and tailor movements to all fitness levels.

Amanda Biggs 8 years ago

Fantastic experience: Groundworx CrossFit is more than just a gym…it’s a family…a place where I have met new friends…where coaches and teammates support your accomplishments and help you work on your weaknesses.

Sara Abbs 8 years ago

Fantastic experience: Everyone is welcomed here...all fitness levels. They will modify the workout to what you are able to do safely. The coaches are very supportive and encouraging. They always are attentive to correct form. Its a community of people who care and cheer you on to do your best. I loved it so much after the first few months, that I signed up for a year! Much better than going to a regular gym...I could never go back to one now :)

Linh Benson 8 years ago

Fantastic experience: What can I say about Groundworx?!! Everyone here is like family to me. I've been here for almost 3 years now and I love everything about it. All the coaches are so knowledgeable and friendly. I love the fact that there are a variety of classes available and for all levels of crossfitters...from beginners to the experienced you can do an On ramp classes, Crossfit classes, Sweat classes, Olympic classes and even Compwod classes. I used to just go to a regular gym, but was not able to get the results I wanted. Now I'm in the best shape of my life since joining Groundworx. So if you're thinking about starting crossfit and love a family environment, then Groundworx would be a great place for you. Even if you've never worked out before, their experienced staff will make you feel welcome and will help you reach and exceed your goals.

Catherine Rovina 8 years ago

Fantastic experience: As a member of Groundworx for about 5 years I can safely say it's a second home for me. The owners are caring and thoughtful to the continued development of our gym. .Our coaches are also attentive experienced and knowledgeable and ensure all members are attended to regardless of level of your athleticism . The atmosphere is encouraging for all levels of fitness but still fosters healthy completion amongst those athletes who wish to push a little harder . What I have enjoyed the most are all the wonderful friendships I have made over the years as a member. We welcome all new members into our gym and are honestly like a family . I can say I have worked out at all different times at our gym and every Wod time is a fun time! I love my Groundworx family !
