I didn't even think I liked boxing when I first walked in (tbh, I didn't have gloves for that first class ) but here I am almost 2 years later. The classes give variety throughout the week, with a balance of cardio and weight training, and the booty classes are 10/10. 6pm class over 6am any day though! read more

We signed our 8 year old up for the youth classes. Best decision we've made for him. Kadeem & Eric (coaches) are BAD ASS!!!! The classes are upbeat, enthusiastic, energetic and so much more. The facility is very nice, very clean and a super inviting environment. The older kids are so helpful and patient with my son. Some of the most respectful kids I've seen. I believe it's because of the energy and amazing vibes, structure and impact that these coaches exemplify. The only bad thing I have to say is that I waited too long to sign my son up. Looking forward to a long boxing life here at KS FITNESS!!!! read more

This is the longest I've been part of a gym, that's how much I love it. The workouts are great and the trainers and fellow members are even better. I genuinely have made a lot of good friends from this place. So, much like The Olive Garden, if you're here, you're family. And also...f you Gary! read more

They added protein shakes and they are NEXT LEVEL. If you are serious about making improvements on yourself they have your back. Calculated macros, delicious flavors, all made by people that want to see you succeed. Ain't nothing better after a tough workout than an ice cold protein shake that tastes like a cheat meal. read more

KS Fitness - Oreo Over Training Protein Shake. Over 35 grams of protein, only 10 grams of fat. - Trainers Near Me - Fullerton, California

I have been working out on my own for years. As I've aged, staying motivated has been a hurdle that has been getting harder to overcome. I had been searching for a suitable gym for months prior, when I finally discovered KS Fitness. I reached out via social media and Kadeem promptly responded on what was recommended to bring prior to my first class. They have an app that is very user friendly and offer different programs suitable for everybody's fitness goals. The classes are challenging but all of the trainers are very accommodating and will assist with guidance regardless of your fitness levels. Most importantly for me they have classes that start as early as 5am, which is arguably the best way to start your day. The class sizes are limited which give the trainers the ability to suggest improvements in form and are there to push you at your own pace. I'm currently just on my third month of membership, and planning to be a member for long into the foreseeable future. read more

Best gym with the best people! Come for the booty gains and stay for the friendships. They have great group classes that are high energy and give you a good sweat or 1 on 1 training if you have some specific goals you need help with. I honestly love this gym and it's become a second home for me. The coaches make sure you push yourself, while doing proper form and technique. When you come through, tell Coach Steph Anthony sent you. read more

Best trainers ever. Greatest atmosphere. I have struggled with gym anxiety ever since I started working out over 3 years ago. I have been doing private classes and their regular classes for over a year now and all the trainers and members have been very supportive of my goals and only a text away if I ever have questions on fitness or nutrition. They also have a protein shake bar and meal prep INSIDE the gym. Super convenient! read more

From the first time I stepped into the gym in 2018, this gym has been nothing short of amazing. The workouts are challenging regardless of fitness level because the trainers know how to encourage and push you according to your abilities. It's obvious how communal the gym is as soon as you walk in...everyone is so nice and encouraging to each other, even if it's your first week or your fifth year! Personally, this place holds a special place in my heart because some of my closest friends have come from this gym and I have never felt stronger. Run, don't walk, to KS Fitness! read more

It was a great two sessions wish I could have gone more but the workouts did kick my butt

I have been going to KS Fitness since 2020 and I love it! The work-outs are fast (45 min classes) and effective, and the community is encouraging, fun and keeps you motivated. Our coaches know their stuff and push you to be better, get stronger and challenge yourself with each work-out. Even tho it's not about the weight loss, I have lost 10+ pounds (and have kept them off!) since working out here. The workouts build your endurance, strength and confidence every single time. They also offer additional challenges and events to keep you motivated throughout the year. My first 6-Week challenge was the kickstart I needed to get my fitness and health to the next level. Cannot recommend this gym enough - even if you just try it out for a couple weeks, I guarantee you'll feel better and be stronger at the end of your session. Much love KS Fitness fam! read more

This gym has a great culture and super friendly staff. Great environment with high-energy group classes. It's truly a great place to get your health in check. I highly recommend this gym. read more

Used to be a serial gym hopper until I joined KS. Never been so dedicated to a gym and have been coming here for 3 years. Workouts change everyday and energy is kept high. Come see Kadeem! You won't regret it. read more

What a great boxing gym. I had driven by this gym for many many years and never bothered to join it until one of my friends joined it, and dragged me in there. The classes are super energetic and get you sweating real quick. All of the coaches are there to support you so that guy can achieve your goals. Thank you KS for being so supportive. read more

Best gym and great staff. They offer HIT classes, 1 on 1 training, and boxing. The trainers are all really friendly and knowledgeable. By far the best workout I get is when I attend a KS Fitness class. Highly recommend!! read more

I am totally loving this gym, even though it's totally kicking my a**! I suppose that is a good thing. This place is located in an industrial area and I have probably driven by a few times over the past year but never noticed it. Well I'm glad I have now. The boot camps are challenging and ever changing. It's exciting to find a class that doesn't stick to the same mundane moves. Intermixed into the boot camp is quite a bit of boxing on a punching bag. It's Great! Gets all my aggression out. I've never walked out of a class as Sweaty as I have from here. The instructor Kadeem is a good balance between stern and Goofy. He pushes everyone just enough to get one more rep in but then will bust a dance move to make everyone laugh. I'm really enjoying my time here and that says a lot because I hate working out. Be sure to check Groupon for a great deal on classes here! read more

Joined a class today. Yeah a lot of sweat and felt great after the class. I like boxing part of the class and will join more classes definitely. They offer very flexible pricing structure so I can select either credits/ one time class / monthly unlimited membership which is great for me as I am pretty busy with my work and travel. Kadeem is very kind and responsive! trainers are also nice and supportive! You should check this place out if you want to have a great workout classes! read more

I never saw myself having a personal trainer or a consistent training plan until I met Kadeem and the amazing trainers at KS Fitness. I challenge everyone to come for a class or to take a second and come meet the people at this facility, because it IS worth your time. read more

I've been working out here for about 4 years now and I won't ever leave! Kadeem has built the most amazing gym full of trainers that truly care about our workouts, form, and well-being in and out of the gym. Everything is kept so clean, he's always updating things to make sure we get the best of everything, and he's always coming up with cool challenges to hold us accountable . Coach Steph makes sure to help during and after class if we need the extra help, and Coach Eric us new but really cares a lot to make sure we do well in class. I've brought so many friends here and can't wait to celebrate year 5 with KS ! read more

I would highly recommend any and everyone to come here at least once but if u come I can guarantee u will be tryna come back as soon as u can!!! Thank u so much ks fitness fam for helping me in my journey to become fit and a better person all around u guys are amazing read more

I love KS fitness! I've been going there for about 4 years and I cannot see myself ever leaving this place. Classes are fun but also challenging, the instructors/trainers are always making sure we are doing the exercises correct, their hours are very flexible and on top of that, KS fitness is a community of people that love and motivate each other. You'll find a family in there :) read more

I really enjoy working out at this place! I had been looking for a good place to work out for a long time. After trying this place out for a month, I really enjoy KS fitness. Ultimately, you can go as hard as you want. If you are a person that is looking for a good place to work out, non-intimidating, with a good group of people, this is your place. The workout sessions are high-intensity interval training (HIIT) for the first half and then a bit of light boxing. During the week, the workouts switch between legs and arms. Wednesday, are core & boxing days. I highly encourage you to start on a Wednesday if you have not been working out. If you decide to try this place out, talk to Kadeem. I hope this helps you. read more

Kadeem and Erin are amazing trainers! It's not easy with my busy schedule to put time aside to work out. I usually find myself spending 2 hours at other gyms lagging on my work out. Here at KS Fitness I am pushed and properly guided through out the routines in which i benefit the most from the hour. KS Fitness understands that everyone has different physiques. The routines can be individually modified to your physical needs. I have lower back and balance problems that Kadeem and Erin pay close attention to. I no longer have to worry if I'm doing it right or if I'm gonna injure my self or if I look plain ass stupid. Don't worry they will let you know. What makes the place great is the decor. Kadeem has a fabulous taste in black and red. JUSSSST KIDDDING. lol What makes the place great is the happy and upbeat atmosphere that the trainers bring to the location. Training with them makes that hour work out fly. Kadeem is always full of information especially when it comes to nutrition. He strongly believes diet is a big key to achieving your work out goals. "Eat clean, train dirty". He also offers meal planing schedules that cater to your body's needs. Yes KS Fitness pricing is higher than la fitness or a 24 hour pass. I just see something off about the analogy of paying a monthly charge and doing work outs that you just YouTube or learned online that are obviously ineffective. Why not pay a little extra and know you are doing the right thing with people educated in the feild? Besides I'm not a fan of waiting in line for a sweaty stinky machines that other men have smeared their slimy bodies on. Kadeem keeps his gym clean. He disinfect the mats between classes and wipes down the equipment before everyone's use. Really I can keep going on how amazing this place is but really you should just give this place a try. KS OFFERS A TRIAL PERIOD. So take advantage of it and just see why I love this place!! read more

I've been coming here for years and have now added 1:1 training to my routine. Best decision ever! And no- I don't love working out (or waking up early to work out), but I do love what this experience has done for my body and especially my mental health. Highly recommend this gym! read more

Kadeem is great. Steph is fine. This a really friendly place with trainers that care about your fitness. Come & check it out!

I've been going to KS Fitness for almost 3 years and this place is truly a second home for me. I was working out on my own for a short time before, then gave KS a shot through a friend's suggestion. Since my first class, I signed up that day and have been going to the classes consistently ever since. There is no other gym that I've ever found that has such a positive atmosphere and everyone encourages each other. The trainers are the best, the people are the best and I've been grateful enough to build true friendships here. I've learned so much about fitness and have made some big changes in my physique and lifestyle as a result from learning from the amazing people here. Highly recommend you sign up for the 6am classes! Best morning crew ever! read more

I have been battling weight loss and fitness for a long time. I found a few trainers that focus more on my wallet then my health and fitness. A few months ago I met Kadeem at KS Fitness. From day one he made it his mission to help me reach my first fitness goal. Less than 3 months I lost 30 pounds AND I gained a desire to keep going. He went from my trainer to my brother. If you are looking for a place to feel comfortable, receive professional guidance but qualified trainers that care about YOU then you must contact KS Fitness. read more

Very personal hands on gym. They care about their clients and make special adjustments when needed. Super dope workouts. Boxing is fun, tough, and you get one on one time. The first workout had me on my hands and knees trying to breath "In a good way". Best workout I have had in a while. read more

I have been going to KS Fitness since January. Kadeem is an amazing trainer that has a personal interest and relationship with each of his clients. He pushes you beyond what you believed possible and you leave each class with a feeling of great accomplishment. I am a busy mom, and student and often fall off track, I regularly receive text messages checking up on me and encouraging me to stay strong and focus on my goals! I probably would have given up had it not been for the continued support from Kadeem. The classes are fun and upbeat but be ready to sweat your butt off!! read more

KS Fitness is the place to go if you want a personal touch added to your structured workouts. Kadeem is a natural motivator and genuinely cares for all of his at students. I'm in my mid 40's and have been going there for near 8 months, Kadeem's energy is what keeps me coming back. read more

This class kicked my ass in the best possible way! It's such a sweat fest! Kadeem really knows how to push you to your full capacity and get the best out of you! I really do feel such a great sense of accomplishment after this boot camp style workout! Thanks Kadeem! Can't wait to be back! read more

I am so happy with KS. Was a little worried at first ,thinking this was a busy group session place. I was very wrong. I love it . Been going now for weeks. 1 on 1 with the owner Kadeem has been amazing. He knows his stuff and always gets the most out of me. I would highly recommend trying KS. I'm in...... great studio to workout and upstairs to box. Got to check it out. read more

This place is a GEM! I found KS Fitness through Classpass. It was easy to find and there was plenty of parking in front of the gym. It's in an industrial-ish lot so it was pretty empty about 530 pm. I got to class early so i could sign in, change and get my bearings. Upon arrival, Glenn stopped what he was doing to get me checked in and show me where to change. After I changed, he invited me to check out the current class' boxing session. I got to see the format of class before it started so I wouldnt be so lost during my first class. The HIIT portion of class was great. Kadeem did a great job pushing us to get heavier weights, more reps and finish our sets. I liked how Glenn helped out correcting form and make sure we knew what stations we were rotating to. There are a lot of stations, a lot of different rounds, but it goes by fast! The boxing portion of the class was AWESOME. Each person gets a chance to spar in the ring. You get to practice punching on heavy bags until it's your turn to spar. The place was clean, did not smell like gym funk, and was pretty well ventilated. The equipment has been maintained well and is in good condition. Overall, a great workout at a great facility. read more

This is the first exercise program I've ever been able to stick with. Kadeem cares about us. It's more than a gym, it's a family. For reals.

I found KS fitness on groupon and decided to give it a try. This place is so awesome and Kadeem is a wonderful trainer!!! The boot camps kick your butt and are challenging..but you also can go at your own pace and Kadeem offers modifications if needed. I like that each day during the week they workout a new muscle group so it doesn't feel like you over-do it with working every muscle in the same day. I have to say I am very impressed at how clean the gym is, how nice all the members are, and how dedicated Kadeem is to helping every person succeed. Love this place and I will continue to workout here even after my groupon expires!! read more
