I’ve been training at Relentless Gym with Coach Art since last year, and I can’t recommend it enough! Coach Art is incredibly professional, patient, and knowledgeable. His teaching style is diverse and engaging, making every private session both challenging and fun.

The gym itself has an amazing atmosphere—welcoming, supportive, and full of energy. It’s a great place to not only improve your skills but also meet like-minded individuals who share a passion for boxing.

Whether you’re a beginner or more experienced, this gym offers something for everyone. I’m so glad I found it!

I've been training at Relentless Boxing & Training Center for a few months now, and it's been an incredible journey! The workouts are nothing short of killer, combining intense cardio with technical boxing drills that really push your limits. Each class is about an hour long and runs on Tuesdays, Thursdays, and Saturdays. The sessions are well-structured and instructed, focusing a lot on mitt work, often pairing you up which makes the drills both fun and challenging. The pricing is very reasonable, especially considering the quality of training you receive. It's a fantastic place to sharpen your boxing skills while getting in top shape. Highly recommend for anyone looking to up their game in boxing or just seeking a great workout!

If you're looking for a great boxing gym, I highly recommend Relentless. Coach Art is super professional, knowledgeable, and incredibly nice--he was a professional fighter for many years and brings a wealth of experience to his coaching. The gym has a spacious and well-maintained environment, and the members are very friendly. Whether you're into cardio boxing, technical training, or pursuing a professional path, this gym has it all. I've been training here for a year and have seen significant improvements in both my skills and body conditioning, yet there's always more to learn. Plus, the gym recently updated its heavy bags and ring--come check it out!

After trying a few different "boxing" gyms, I finally found the real deal at Relentless Boxing. Anturo is a fantastic coach, very professional and always willing to help. The gym has plenty of space, so you're not crammed in like sardines. I've been training here for a few months and have learned so much from the experienced boxers who train alongside me. The classes are tough but incredibly enjoyable, and definitely a world away from commercial cardio boxing. I highly recommend this club to anyone serious about learning the art of boxing.

Great Boxing gym that will push you hard. Classes Monday, Tuesday, Thursday, Saturday but if you ask you are welcome to come in during open gym times. When I was there everybody was kind and welcoming, coupling that with Art being a fantastic boxing coach makes for a great experience.

I've been taking lessons with Art for a few months now and have loved every moment of it! Art perfectly balances pushing me to improve and perform my best without feeling too much pressure. I've learned a lot about boxing technique and have noticed big improvements in my cardio, strength, agility, and reflexes.

Boxing lessons are the highlights of my week and provide a great escape from the grind at work. Everyone I've met has been super friendly and inclusive - Art has really built a great community and I highly recommend anyone who's thinking about learning how to box or even just getting fit to come check it out!
