Terrible experience at this neglected gym!…read more I joined this gym on the beginning of this month (April ) and got my membership canceled by the owner 12 days later which I only used the facility 3 days to workout. I have multiple gym memberships from commercial to private gyms and this was a first. I always clean and unload the machines after each use and this day was not a different day. I was approached by the manager of the gym which is the owners brother in a disrespectful way, telling me to rerack the weights from previous machine which I clearly unload the machine, but the gym does lack on weights stations to unload to it, so I left on the side of the machine organized which he told me to put where I got them from, which was from walking around the gym grabbing from machine to machine and I told him that it doesn't make any sense when they lack on stations to drop the weights on it. Although I went back and did what he said. I pay to go there not to work there. 2 minutes later as you see the screenshot, the owner Mario texted me saying it is courtesy but them is rules which is not on the contract anyway. So they canceled my membership when I didn't even left the machines loaded or weights on the floor. Unfortunately this was a act of discrimination from the manager to me as a person as there was one other dude earlier time leaving all weights on the machines and nothing was said. I was going to cancel the membership on Friday due to this gym been neglected for long time. Machines are mostly ripped off , tapped or some broken. Machines are on top of each others or next to the walls with wires or ladders next to or impossible to load them, so many hazards. Bathrooms are dirty and trash all over the place most the time and barely anyone at the gym. Men's locker room is a mini one dirty with broken toilet and main door doesn't even fully close. What you see on IG are all filters and angles, they clearly misleading people, I joined online on their website from social media, as if I add gone see it before in person I wouldn't ever join it.

Honestly best gym I've ever been a member of, by far the best machines, you can tell the owner…read moreknows his stuff. The layout is a little weird and can feel overcrowded at times but I feel the negative comments on that are a little over blown. The music can also be too loud on some days, to the point where you can't even hear your own music with headphones on but I do appreciate the fact that customers are allowed access to the aux. Another gripe I had, which was a big one considering how much monthly you were paying was that several machines would be out of order on a consistent basis especially in the cardio department, as well as a urinal in the men's restroom. It's been a few months since the last time I was there, so I don't know if that's been resolved by now or not. Owner is a really cool guy and was very responsive to all my inquiries and messages. Main reason I'm not going here anymore is because of a one-off, petty dispute my friend had that was both initiated and escalated by a trainer working there but outside of that, it's arguably the best gym in the ie.

By far a great experience to be training with Kacey, after researching online for a trainer who…read morecould help me out with my goals I came across his website. Seeing all the good reviews and results of his clients I was convinced to make a consultation with him and definitely couldn't have made a better Choice. I'm 23 years old never lifted weights and I was a bit nervous going in but he's very professional, patient, and great at communicating with the routines, with your form, and nutrition. I've been training with him for about 3 months now and I'm just so thrilled with the results I was able to loose 7.2 percent of body fat and gained about 3 pounds of muscle. Like I said I've never done weights beforehand and for me it's a great accomplishment, can't wait for future results!

I originally came in just wanting to fix my form and learn how to lift properly, and that's what…read moreI've been getting. Kacy is big on progression and basically operates under the assumption that you can always go up in weight, which has pushed my strength up (especially hip thrusts and RDLs). It's small group training, which keeps the energy up because everyone's working at the same time. He'll keep you accountable and make sure you finish your sets and there's a decent chance you'll leave with a random nickname you didn't ask for but it does keep things entertaining. In my first month I've already seen measurable changes in strength and body composition, so it's been interesting to see the progress show up pretty quickly. Curious to see what the next couple months look like.

This gym is completely unrecognizable from what it used to be. What once felt like a true community…read morenow feels like a corporate rebrand that forgot the people who built it. The culture has shifted away from the diverse, welcoming vibe that reflected Ontario and into a loud, performative, hyper- bro, heavy metal/rock atmosphere. It's not technically "bro only," but if you're not part of that energy, you're effectively invisible. When new ownership came in, they fired the long-time employees who made the gym feel like home, and since then the environment has become uncomfortable and oddly transactional. The vibe now feels performative rather than genuine. The trainers are loud for the sake of being loud, hyped to an almost cracked-out level that feels disingenuous instead of motivating. The favoritism is impossible to miss. I'm here weekly, and Miguel, the owner, has never once acknowledged my existence. No hello. No nod. No eye contact. Meanwhile, he's fist-bumping the men on either side of me like it's a frat boy reunion. Every. Single. Time. As a woman, it's hard not to see the pattern. He'll happily engage with the conventionally attractive women, but if you're just a normal person trying to work out, you're ignored. If you're not ripped, or radiating alpha energy, you're background noise. It's giving used car salesman confidence with a dash of outdated male chauvinism.. A gym should empower people and make them feel welcome, not dismissed or overlooked. It's genuinely disappointing to watch a once inclusive space push away the very community that made it successful in the first place. P.s. please diversify the music again! We need some reggaton, rap, and EDM... It's missing some Ontario culture.

The 4 PM class with Autumn definitely caught my attention. I usually work out with my headphones in…read moreand tune everything else out since I'm not in the class, but I forgot my headphones this time, and her energy still came through. The workout itself looked intense and pushed the class to the edge. No one was coasting, and the pace stayed high the entire time. Autumn stayed locked in with her group, motivating and pushing them without letting the energy drop. You could see how much the class fed off her. Her motivation felt real, not forced, and it showed in the effort everyone was giving. Even just watching from the side, it was obvious her energy is unmatched. She's the kind of coach that makes people push harder and stay engaged.

I have worked with Greg for only 7 months, consistently once every week, and I have seen real…read moreresults with his training. Greg is down-to-earth and a no BS trainer that pushes you to become the best version of you. His charisma comes from his outspoken attitude and experience working as a personal trainer at other gyms. I can tell that he is very smart and well-informed in the type of work that he does, and I strongly believe that will carry him far along for his own personal goals. He is also very professional and knows how to think ahead. If a gym or environment does not meet the needs of his clients, it does not meet his. This is someone that knows how to work with people and will definitely have a bright future ahead of him.

100% recommend I…read morecame to Greg as a referral from a friend who had been working with him and got great results. I wanted a female trainer but my girlfriend insisted he was great and I saw her results and decided to try him out. I have been amazed by his fitness knowledge! Any questions he answers with research and stuff he's tried and cuts through all the BS. Since I've meet him a few months ago, he's been on a cut and you can tell he knows his stuff because he gets the results he wants for himself & his clients. I request heavy on the lower body & my legs look amazing! I feel super confident wearing short skirts this summer & putting on a bikini at the beach every week due to how toned I look! He is efficient! My one-on-one sessions are one hour but I put in work! He personalizes each work out to me depending on my goals and we get to it! He makes sure each rep & set are optimal for me and we adjust throughout the session depending on what my body can do that day. Greg has taken me to failure, I've cried, I've puked and I keep coming back! He pushes me in just the right way, something I could not do on my own. My workouts with him are super fun and I always look forward to them! I have no reservations about endorsing Greg to anyone! I also would like to add I have a PCL tear and he makes sure I'm safe. I've had major improvement in my chronic pain since gaining muscle that's improved my daily life.
