This gym truly stands out. The instructors are the heart of it—they’re incredibly cordial, knowledgeable, and patient with everyone who walks through the door. What impressed me most is how much they genuinely care about their students’ progress. They take the time to break things down, correct technique, and make sure you’re growing at a pace that’s challenging but safe.

The facility itself is spacious, clean, and well-equipped. Whether you’re working on fundamentals, conditioning, bag work, or sparring, the gym has everything you need. There’s plenty of room to move around, and it never feels overcrowded or chaotic.

Overall, it’s the kind of environment where you feel welcomed, motivated, and supported—whether you’re a complete beginner or someone with experience. I always look forward to training here, and I’d recommend this gym to anyone serious about improving their boxing or simply wanting a positive, uplifting training space.

You do not improve from this gym. They only care about how much you pay and if you don’t pay enough you will not get attention and they don't teach you boxing skills they just throw you immediately on to the bag or shadow boxing without any knowledge and people with no experience jump in the ring and spar hard with each other without coaches saying anything. Overall i don’t recommend it and if you wanna get good at boxing go somewhere else.

For the short amount of time I was there it was the greatest experience. Every coach was very supportive especially the morning staff such as coach Corey but someone I saw as a true father figure was coach Juan. They show that they really care and want you to learn. We all went through struggles together and somehow found love into a sport that not many come to love because of what many depict. Yet this was my first and the gym I will one day return to. Thank you for everything ISU, if it wasn’t for me moving I would’ve definitely stayed.

I signed up for a beginner-friendly boxing program here for $250 after discussing with the owner (Dan) that I had zero boxing experience. Unfortunately, my very first class was a disappointment from start to finish.

Dan invited me to arrive at 5:45pm on my first day. When I got there, the doors were closed, no one greeted me, and no one explained where to go or what to do. I sat in a chair awkwardly until a random person asked if I needed help. I told him I was looking for Dan, only to later find out Dan had a family emergency and wasn’t there. At the time, I had no idea and felt completely out of place.

The person helping me seemed confused that I was even there, saying he’d only been told about someone else arriving that day. He started asking how much I paid, how much I owed, and whether I was supposed to get my gear (gloves, wraps, etc.). My first impression was that the place was disorganized.

Then came the class itself. For a “beginner-friendly” program, there was little to no instruction. We started with shadowboxing, but as someone brand new to boxing, I had no idea what I was doing and no one explained the basics. Then we moved to punching bags, again with no real direction on proper technique. I left feeling lost and discouraged.

When I later brought this up to Dan, his exact words were: “If you want more attention you need to pay more.” That was incredibly off-putting. If that’s how it works, it should be made clear before someone signs up, not after they’ve already paid.

I asked for a partial refund given the poor experience, and at first, he agreed to refund $150. But when we spoke on the phone, the conversation turned into an argument about the situation rather than resolving it. Eventually, he agreed to refund only $125 of the $250 I paid.

Overall, my experience was disorganized, unwelcoming, and not beginner-friendly as advertised. I left after one class and would not recommend this place to anyone looking for a supportive introduction to boxing.

I bounce a lot between working a day shift and night shift but either way they have classes all through out the day which is amazing and can’t say I don’t have time as an excuse not to show up. So whether you’re a morning person or night person they got a class time for you.

ISU’s an awesome boxing gym! I’ve been training there for about 7 weeks now and plan to continue. I train with Coach Corey and take the semi-private classes in the morning 3 days a week. I’m 29 and hadn’t done anything athletic since high school, so I was very nervous to join a gym and worried that people would judge me for starting late or for how scrawny I was (I’m 5’11” and started at 125 pounds). I was really happy to find that I had nothing to worry about at ISU. Corey is welcoming, fun to work with, and genuinely cares about his students’ progress. On top of that, he’s extremely knowledgeable in boxing and general fitness, a great teacher, and someone who pushes his students to be their best. The classes are intense physically, but I always feel great after and leave the gym excited for the next one. On top of wanting to learn how to box, one of my goals at ISU has been to gain muscle mass. I’ve gained almost 10 pounds since starting at ISU 7 weeks ago, something I’ve never been able to do successfully by myself. I feel healthier now and have much more energy throughout the day too. Guidance from Corey and Dan (who helps with management at ISU) has been super helpful in achieving all of this. Dan has also been super welcoming and helpful with scheduling. I took a class with Coach Juan when I had to come in on a different day once, and he was great to work with as well. The community at ISU is awesome and very supportive. I highly recommend ISU and Coach Corey!

I’m 24 years old and my faith has been restored just from investing in myself with ISU!

I’ve always wanted to be one of those people who wakes up early before work/school to workout, but could never find the motivation or a program that interested me enough to make it a habit. Since joining ISU and meeting Coach Corey and the AM squad, I’m hooked! I come to the gym as many mornings as I can- often times to the 6AM class. Corey has a coaching style that could help anyone succeed- he provides support and encouragement, while also pushing his trainees and challenging them to regularly meet current goals and set new ones. Admin staff, other trainers and patrons are also very welcoming and collaborative, which makes it an even easier choice to continue training week after week. The time slots for classes are varied (helpful for those with a busy schedule), the location is good, the gym space is open with a variety of equipment, and the parking lot is large and easy to navigate. Highly recommend!!

Great facility. One of the best I've been to in LA. Great options for classes, semi privates and privates. I did the semi privates and group classes and got great training.

Overall ISU is a pretty solid place to workout and train in, the coaches are nothing less but outstanding, pushing you to perform the best you can and improve everyday, the facility in which you train in is exceptionally well designed for a variety of goals. I personally reached my goals during my time there and I felt so proud every time I finished a session knowing that I improved everyday I went. If you are new to boxing or even exercising do not worry, the coaches are extremely respectful and are there to help you learn what you need to improve upon. A solid 5 stars for me, I've had zero problems, the price you pay to go is equivalent to the service you gain, which as stated before is amazing and fair in my opinion.

I have been training with Coach Corey at ISU for the past 6 months.

Since then not only have my boxing skills improved significantly , my physique has changed for the better but as a person I have grown into a better individual all thanks to Coach Corey !! Ever since meeting Coach Corey my life has completely change all
thanks to him .

Every training session is like family because of the community that Coach Corey has established since been with ISU for the past 6 months.

ISU is a great boxing gym because of the community that has been established. My only complaint with ISU is the way that the ownership has handled the whole loss of power.

The gym has been without power since early November 2024, and as someone who relies on the gym for a post-training shower and the lack of hot water has been incredibly inconvenient. This ongoing issue reflects poorly on the professionalism of the gym’s ownership, and I’m not the only one frustrated by how the situation has been handled. Many others share my concerns about the lack of resolution.

I started training at International Sport Union about 2 month ago and I couldn’t be happier with the experience I've had! The gym has a welcoming atmosphere and is well-equipped for all levels, from beginners to advanced boxers. Coaches Ken and Alex are phenomenal trainers who also have shown a balance of professionalism, motivation, and technical expertise. I highly recommend anyone who looking to get in shape or just want to box to go check them out.

ISU is where it’s at! After coming here for a full month I’ve felt the best I’ve ever felt in all my years. I love boxing now and the coaches push you and motivate you and really want to make us the best we can be. It feels like family here and it’s a great place to learn the skill and maintain. Coach Dan and Corey are amazing coaches they showed me so much and I look forward to learning more in the future from all the coaches ISU has to offer. If you’re new and want a place to learn this is the place to learn the basics and get an amazing workout and learn to really fight. If your more experienced and want to learn more and spar with some good fighters this is it. What makes ISU different is 1) the family aspect 2) the training and intensity 3) the wide level of fighting Experience. I promise you won’t regret it join the team make friends and learn to fight-Izzy

ISU is the best boxing gym in town. It’s more than a gym it’s a family. All are welcome and the pricing is fair. They give you the confidence to defend yourself and the ability to have discipline and strength against all odds. Give them a shot you won’t regret it! I go by Sammy there (it’s LA what can I say :)

I started about 4 months ago and my body has changed, my posture, physique and recovery rate have improved. I recently competed in my first amateur bout and thought I lost (in a VERY questionable decision, hey it’s boxing) the experience and expertise related by the coaches were second to none.

For anyone looking to switch up there exercise program to something more challenging and frankly rewarding I HIGHLY recommend talking to Dan and getting started with the two month plan at ISU Boxing! When you join and think you’re ready ask for a sparring session with Sammy! I’ll be waiting 🥊

Not a good environment. They very disrespectful and rude to me. I'm visit this gym cause I looking for a place where I can take exercises for the competitions and stuff like that but this weirdo guy named Ken starting mean to me and ask my age. I'm in my 30's so I'm not old at all plus I have fight experience and priviusly I do some underground fight too and won! So I'm not amateur also but this guy said no it's too late.
Yeah maybe for him yes, but not for me!!!
Also I noticed everyone there is Armenian but
I'm not so maybe he just doesn't wanna someone who's not like him!...So however bad experience but I'm never give up & make my goals into the reality anyway! I'll go find an another gym where is everyone welcomed not just some people...
