Amazing amazing gym. Went around for a year till I found a gym that encompasses a true boxing gym. This gym has the classes available for those who want to simply the lose weight but also allows for those who want to learn technical boxing, muiuy Thai and mma. Basically, you can make what you want from the gym because it is so versatile. Also, you don’t feel like a ‘member’ or a number but like family. When I did not go for a couple of months, Diego the owner greeted me like family, asked me how everything was going, if I was OK. It was an excellent feeling. Great customer service. I’m a big fan of reviews so what you need to know is. It’s not a spa type gym, it’s for the strong hearted! The gym seems to be in an old garage with all the weights on the bottom floor and you go up the ramp to a room filled with bags, a cage etc. when you walk in you smell rubber and sweat and you want to add your tears and sweat to the aroma indicating that real work was done here! I come here during the day when no classes are there as well and the upstairs and I do all my conditioning there. Also, great personal training and glove work for a reasonable price. Free parking also which is clutch.

I’ve been active in the fitness realm consistently for the past 7 years. I’ve experienced a range of fitness facilities from boutique style gyms like Iron Flower to large «commercially driven» sites, like LA Fitness. I love KnockOut Zone for its atmosphere (no pressure/​friendly culture yet balanced competitive environment).
The cross fit and boxing classes are well worth the price for the experienced level of fitness coaching provided here. I always shop around. (I groupon/​embrace trial periods throughout the Miamj). I am mom of 3 and pride myself on living a healthy and fit life. I look forward to the challenge Diego presents. I have gained more from KO Zone in 4 months than I accomplished in a year at other locations.
I come to train hard and the customized work outs at KOZ are geared for major fat loss, strength and conditioning. There are additional trainers that are such an awesome compliment to Diego’s style. If you have not tried KOZ and you reside or frequent Mimo/​Wynwood/​Brickell/​your are truly missing out.

Amazing gym with helpful staff! Large facility with weights and martial arts equipment. I love that it’s not overcrowded like other gyms in the area, it’s almost like a private gym. You can usually come in do your exercises and be done without waiting 30 mins to use the bench press.

I couldn’t be happier with my choice of joining knockout zone over a year ago. It’s not just for crossfit, they also offer muay thai, MMA, boxing and plenty of other classes. If for any reason you don’t want to take any of the classes, you always have a wide range of machines and weights that you could use.
All the instructors are amazing and they definitely know what they’re doing. They’re all there to help you reach your goals and will give you the push you need to get there. The owner, Diego, is not only an amazing trainer but also a great person. He’s always willing to help his members out, and eventually everyone there will be like a family to you.
This is definitely one of the best gyms you’ll ever join, so don’t think twice about it and get your butt over there lol

The trainers are good, and it’s good for people who want to build muscle. but the class schedule is deceiving. It says bootcamp and crossfit at 5 and 6 pm every day. That’s a lie. Crossfit is offered at 5 and 6 two days a week. Bootcamp is not offered in the evenings. You need to be honest with your customers.
The other thing is that if you don’t cancel on time your money won’t be refunded even if you don’t use the gym.

I have been following Diego, the owner of knockout zone and one of the coolest, nicest, most badass trainor/​business owner/​family man and ninja I have ever encountered, from the very start !
When he opened this place up, he made it true to his vision of what a gym should be: a place where people who are serious about giving their 200% meet once a day — to sweat/​fight/​Push/​Yell/​Bleed/​find strength they didn’t think they had, and do it all over again the next day. If you are looking to show– off your muscles and chit-​chat with your bros between sets about your latest tinder match and macro split BRO, knockout zone is probably not for you, in fact: please stay away. What makes this gym awesome is how authentic and great every single person who attends it is. From MMA champions, to pro wrestlers, to bodybuilders, to karate kids, to whomever is serious about training and leaving a puddle of sweat on the floor, it has a strict: no douche allowed policy ! The knockout zone family is humble and kind, and really embodies the «don’t mistake my kindness for weakness» motto.
It’s simple really: check your ego at the door, try out some of the amazing classes the gym offers /​a diversity that you will not likely find at any other gym, push yourself, find your mentor, and you will accomplish the kind of stuff people write legends about within these walls. I guarantee some serious epicness coming your way and lot of hardcore Rock and Metal workout playlists suddenly appearing on your phone.
Even if you find yourself moving out and have to workout elsewhere you will always feel like knockout zone is your gym and is where you belong. because there is truly no other place like it. It’s like that hot ex that you will never really get over and ruins it for everyone else. Now Get it, start sweating, get ready for some serious changes people !

A true diamond in the rough. It’s a gym that offers EVERYTHING that you could possibly need to reach your fitness goals. No posers, no sitting around on your a** holding down the gym equipment from floating away, no complaints for dropping weights that were designed for dropping, no choking on some chick’s stank a** perfume, and best of all, there’s no microphones/​speakers listening in and sounding off for being too loud in how hard you beast your workout. It’s hot and uncomfortable, just like you should be when you’re crushing it. The staff is approachable and knowledgeable. So go on over and check it out, you won’t be disappointed.

I’ve been going to this gym for about two weeks… and all I can say is WOW! This gym is amazing… I’ve been going to do the crossfit sessions and they are intense. The trainers are knowledgeable and very motivating. I am a PTA, so I was looking for a place with knowledgeable staff who do not jeopardize safety over «gains». I think I just found them. The trainers make sure that all the exercises are performed correctly to prevent risk of injury. Furthermore, the gym is fully equipped, provides a very welcoming atmosphere, like the old style gym, most people pointed out in other reviews. Since the moment you walk in you realize these people are serious about what they do and they are great at it. For one fee you get access to multiple program options (crossfit, bootcamp, Mixed Martial Arts, Brazilian Jiu Jitsu, Muay Thai, Kickboxing and Boxing among others). I can truly say this is one if not the most complete gym I have been to. I’ll follow up on my experience as I progress in my training. Don’t be afraid to give them a try! BTW… No contract necessary.

By far the BEST crossfit I’ve ever been to! The training is great! I’m amazed at the trainers actually being knowledgable and knowing why they are doing. Body mechanics is a MUST for them. All the exercise routines are safe and well instructed. The owner, Diego, is so funny and very nice. They make me feel totally comfortable while I’m there. But what’s mostly shocking is the great price they offer WITHOUT commitment. Trust me, I’ve been to many places, but nothing compares to this gym. Thumbs up all the way!

Great Gym for old school training and cross fit work outs. Not the greatest of neighborhoods, but parking in the back and ample space to get a sweat on. Downstairs you can find machines, free weights and cross fit set ups.
Upstairs are the mats, cage and bags do practice Martial Arts, Boxing or just work out.
Don’t let Owner/​Trainer Diego’s height fool you. He knows what he is talking about and extremely all round. Personal trainers look very fit and MMA/​Muay Thai Senseis are knowledgeable.
Friendly bunch of people to work out with. I’ve been to many gyms in my life, and this one has it all with an old school vibe and often ditto choice of music.

This is a fantastic gym! My husband and I have been going there for about a year. He uses the weight equipment and boxing bags, while I take the Cross Fit classes and use the rowing and other cardio machines. The staff and instructors, who include the owner Diego, are very helpful. They push you to keep moving, while making sure your technique is correct to prevent any injuries. We both highly recommend the Knockout Zone!
