I started with Calvin almost 3 years ago now, and it has been the greatest physical health and mental health choice I've ever made. I wanted to turn my health around at 42 years old at the time and I had already began working out a few months prior to starting with Calvin. He is the best trainer I've ever worked with and a professional boxer that teaches you the nuances of boxing and everything that goes into it. I weighed 250 lbs 3 years ago and today I am down to 217 lbs. I feel at 45 that I'm close to getting in the best shape of my life as crazy as that sounds because of boxing and the training. Its my favorite thing to do and if you decide to join you'll see why. I've played sports and tried all types of exercise and nothing is as challenging and rewarding as boxing and training with Calvin. I would recommend it to anyone who wants to better their health and fitness, become a better athlete, gain confidence, or even if you want to become a professional boxer yourself. Im so glad I found Ultimate Boxing and thank you Calvin for helping me on this journey!

So far I’ve really enjoyed my experience training with Coach Calvin. It’s very personalized and geared toward the goals you want to achieve, which makes it stand out compared to larger, more generic gyms. Calvin is extremely knowledgeable, personable, and makes the sessions both challenging and fun. I also really appreciate how flexible he is when it comes to rescheduling.

The only downside is that it’s a bit on the expensive side. That said, I think the cost is worth it for the more intimate training and the quality of the coaching. Overall, if you’re serious about improving and want a tailored experience, it’s a great choice.

I’ve been training with Calvin for several months now, and I can honestly say it’s one of the best decisions I’ve made. The coaches are incredibly skilled, approachable, and truly invested in helping you reach your goals, whether you're a complete beginner or looking to refine your technique. They create a welcoming, motivating atmosphere that makes every session enjoyable, while still challenging you to push your limits.

The facility is top-notch, with everything you need to train effectively — from heavy bags to speed bags and ample space for strength training. The training programs are well-structured and focus on both the technical and physical aspects of boxing, ensuring you get a balanced workout and continuous improvement.

I’ve seen significant progress in my strength, endurance, and boxing skills, and it’s clear that the academy fosters a real sense of community.If you’re looking to get in shape, learn boxing, or take your skills to the next level, this academy is the place to be. Highly recommend! Thank you Calvin and team.

Calvin and Nico are great. I’ve learned a lot about boxing in the few weeks I’ve been training with them, and I am closer to reaching my weight loss goals. Additionally they are flexible and able to work with my varying schedule. I highly recommend.

I started training with here in about May doing the 1 on 1 boxing training. It is safe to say my experience has been nothing short of amazing. Working with both Calvin and Nico with no prior experience has been wonderful. They both seem to genuinely care about you, and want to help you improve. They both pay attention to the little things, giving you personal advice in AND outside of the sessions. They both have gone out of their way to recommend me gear, and workout plans to help me improve as a fighter. If you are new or an advanced boxer, someone who just wants to learn how to fight, or even just want a good workout regardless of age, I would highly recommend!! No better place to train.

Working with Calvin and Nico has been great! As someone completely new to the sport, they made the experience of learning fun yet challenging. I truly feel that my boxing skill and fitness level improve every time we meet.

UPDATE: My initial review was left at an unfortunate time. I later found out the owner was dealing with a life or death emergency.
I have no problem admitting I jumped the gun.
We are currently clients and are more than pleased with the services.
The owner is a great spirited person whose patience and understanding far exceeds mine.
This a great place if you’re looking for excellence.

My family and I were so excited to train, we woke up early on a Saturday and were thrilled to support a black business. We got to the location at 9am like we were told and no one was there. We waited for 45 minutes.
There was no response to the calls we placed or the texts we sent.
Unprofessional, unacceptable and disappointing.
Be on time.
Do what you say your going to do and keep communication open.

Calvin is an experienced professional boxer who will not only give you a great workout but at the same time teach you how to train, think, and fight like a professional boxer.

Here is what I love about Ultimate Fitness and training with Calvin:

1. It is not repetitive. I learn new boxing techniques/strategies and do new exercises/drills everytime I go.

2. You train to think and fight like a boxer. Through his pro boxing experience, Calvin teaches you how to fight like a boxer which is much more mentally engaging than punching a heavybag till exhaustion which you will likely do at a place like Title Boxing or a typical fitness class.

3. Calvin has really good intuition when it comes to pushing you beyond your comfort level to actually build your fitness.

4. Calvin engages you and gets involved in your lesson. Again, rather than just timing you as you punch a bag, Calvin is constantly giving you tips and pointers as you go through your workout and often has you work on the pads with him, which allows you to practice your punches and defense on a moving target.

5. This guy knows what he is talking about when it comes to the sport of boxing. I've seen him fight in the ring multiple times so you are getting lessons from a legitimate professional.

Calvin is awesome. He will work with you to achieve your goals. You set your goals and he will help push you to achieve them. He is such a sincere and down to earth person that you work 3 times as hard to not disappoint him or yourself. For my goals, I’m very fortunate that I found Coach Calvin because he makes me a better athlete, boxer, and person with our weekly time together (therapy sessions I call them). If he ever changes careers, he is the Counselor extraordinaire. That’s how he is. Give him a shot. If it works out, you will become obsessed with the pace and intensity. If it doesn’t, no worries and know that you might make a life long friend. Much respect Coach!

I recently started training with Calvin and my experience has been great. He explains the details & techniques really well and really pushes you to get better. The facility and equipment is really nice and well maintained as well. I would highly recommend for anyone who wishes to improve their boxing technique; but would also be very useful for anyone that is just looking for an amazing workout.

I’ve been working with Calvin for several months and he’s an excellent trainer. Every time I believe I’ve figured something out he adds a different variation to increase the difficulty of the workout and improve my boxing skills. He’s thorough with his explanations and does well to motivate. He’s also been extremely accommodating with my work schedule. I would highly recommend this gym for anyone looking to learn boxing, improve their skills, or just get in shape.

Really disappointed because Calvin was initially a lot of fun to train with. Suddenly, he stopped showing up. Stopped responding to my texts. I paid for 4 sessions upfront, and I was robbed of the money for the last 2 of them. $150, gone. Be wary.

I can't say enough about Clavin. To start, the facility and equipment is top notch, clean and well maintained. The workouts are fun, different each time, and most importantly challenging. I have been working with him for about 6 months and am in the best shape I have been in since I was a college athlete. I would recommend to anyone and everyone!

Went in for a trial today, and signed up for more right away. Calvin was good at gauging my experience level, and working with me from there. Right away he was able to spot intricacies and gave pointers to improve. I could tell he was a real professional and felt very comfortable working with him. The prices were very fair, and he laid out the structure to the training which I loved. Look forward to working with him more in the future, and encourage everyone to at least give it a try!

Best trainer out there. If you're looking to learn how to box this is the guy to see. Calvin will teach you the proper and right way. Not only has he taught me how to box but how to push through when I'm ready to give up. Its real work over there, and I've become obsessed with every second of it. Go check him out! 10/10

Calvin has been the best trainer for I and my wife. Not only does he offer a perfect mix of functional and boxing training, he keeps on modifying and evolving each exercise routine, making it always challenging for the body. I was never able to achieve similar results by hitting the gym on my own. I needed to be pushed, encouraged and motivated which is exactly what Calvin brought to the table. I will highly recommend Calvin for individual or couples training.

I’ve had the pleasure of knowing Calvin for many years. He is professional, he pushes me when I think I can’t go any more! I like that each time we workout, it’s something different, something creative, something geared toward my goals! Calvin is one of the best personal trainers around!

Ultimate Fitness Boxing is the place to go if you want to challenge yourself to be the best you can be. I have tried every tried every type of gym/workout class and nothing beats a one on one session with Calvin. The mental and physical workout from boxing always helps me walk out feeling my best. Calvin's knowledge of boxing teaches the fundamentals if you are a beginner and helps you advance as your skills progress. You cannot beat learning directly from a pro. Strength training and nutritional advice are also available to ensure you maximize your results.

Simply put, Calvin is the man. Whether you're a seasoned fighter or absolute beginner, he will work with you, challenge you, teach you, and force you to put in work. The sessions are split between technique and cardio, but each session leaves me dead on the floor, and pumped to get back for more work. I'd recommend Ultimate Fitness to anyone looking to get pushed that extra mile.

Calvin’s coaching when it comes to boxing is definitely amazing! He pays close attention to the details and actually breaks down the concepts behind the sweet science. I highly encourage anyone who’s looking to get into boxing or just fitness in general to give it a shot. You won’t be disappointed!
