Whether you’re looking to shed a couple pounds and get in shape or looking to build up your boxing skills, Champion Boxing is the way to go. Although boxing and sparring can be intimidating, Champion's team of inviting, friendly and experienced coaches make it much more enjoyable rather than intimidating. Not only are the coaches friendly, but so is everyone else! If you’re looking for a challenge that will help you build confidence and get in shape, Champion Boxing is great!

Ive been going to champion boxing for just under a year now and its a wonderful little neighborhood gym with a great sense of community. Im not the most consistent but every time i go im met with those who want to improve and help those around them grow.

Reached out via E-mail as they do 6 to 11 year old classes, as I was interested in letting my kid try boxing. Got a response asking me to stop by sometime, they would give me and my kid a tour and discuss pricing. After driving 20 odd minutes we turned up to unwelcoming faces, explained why we were their, wasn’t given a tour, or talk through of how the classes work, just told it would be $150 a month for 3 classes a week, and was given a sheet to fill in. I explained at this point I was looking for my kid to try a class to see if my kid liked it, and it was something my kid wanted to do. I was then given a different sheet to fill in, and told I had to pay $25 for a drop in session. I explained we weren’t planning on doing a class that night but we’re just looking to check the place out that night and find out more about the classes.

I asked if my kid could watch a class for a little while, maybe it could inspire my kid to want to try boxing more and be more eager to join, but was told because we weren’t members we had to get out. In other words because we didn’t give them Money right there and the , rather than try and potentially win new members for future classes they made it clear we weren’t welcome unless we are giving them money.

Very rude staff Will be looking elsewhere.

5-Star Review: More Than a Gym – A True Boxing Family

Joining this boxing gym has easily been one of the best decisions I’ve made. From the very first class, I was blown away by how welcoming and tight-knit the community is. There’s something special about walking into a place where everyone—from the coaches to your fellow members—genuinely wants to see you succeed. Whether you’re brand new to boxing or have some experience, you’re treated with respect, encouraged to grow, and surrounded by people who uplift and motivate you every step of the way.

One of the biggest highlights for me is the sense of belonging. It’s not just about training hard—it’s about being part of something bigger. You quickly get to know the regulars, and the camaraderie that builds between rounds, during warmups, or even just chatting after class is real. It feels more like a team than just a place to work out.

The training itself is top-tier. Every session is packed with purpose: intense cardio, calisthenics, footwork drills, shadowboxing, and heavy bag work that pushes your limits. Even when we’re not sparring, the classes are incredibly effective. I leave every workout completely exhausted—but in the best possible way. Over time, I’ve seen real improvements in my fitness, coordination, and confidence. It’s a full-body workout that actually keeps you engaged.

The coaches are the heart of the gym. They’re strong, skilled, and incredibly knowledgeable, but what really stands out is how supportive and approachable they are. They don’t just bark orders—they teach, correct, encourage, and celebrate your progress. Whether they’re helping you fix your form, offering words of motivation when you’re gassed, or pushing you to keep going when it gets tough, you can tell they care. It’s not a one-size-fits-all program—they pay attention to your growth and tailor their guidance to help you reach your personal goals.

This place isn’t just a gym—it’s a community, a training ground, and a second home. If you’re looking for a place where you’ll be challenged physically, supported mentally, and surrounded by people who want you to succeed, I can’t recommend this gym enough. I’m proud to be a part of it, and I’m excited to keep growing with this amazing group.

I only trained here a few times but the times I did it was a really good gym, the coaches MADE SURE you put in that hard work and if they saw something wrong with your stance or punching or anything they would correct it, hopefully I can go back and train again.

I've been going to Champion Boxing for 2 months now, and I can confidently say that it is my favorite place to be. The coaches are knowledgeable and push you to be and do your best. The other members are always looking out for each other and supporting each other with each and every class. I've been going once a week and I can happily say, I feel stronger, more confident and overall healthier. Before this gym, I could barely sit cross legged without feeling discomfort. Now, not a problem at all. Take the drop in class for $25. Best decision I've made for my health.
