Pure Function Fitness Center

I had a great experience at this gym! I recently took a Core and Strength class with the instructor Hamoon and it was fantastic. The class was challenging but manageable, and the instructor made sure everyone felt supported while pushing us to do our best. The gym itself is clean, well-equipped and has a welcoming atmosphere. Highly recommend for anyone looking to get a solid work out and learn from knowledgeable instructors.

Hamoon is an excellent personal trainer. I had shoulder and knee issues that were preventing me from living the life I wanted. Hamoon was able to properly assess the root cause of my injuries and helped me target the right areas of weakness during workouts. After months of encouragement from Hamoon, I’m finally back to being active the way I want to again. His knowledge and approach to training is unparalleled. Highly recommend

I started training here back in November 2025 with Hamoon. I initially came in to correct my movement patterns and get relief from injuries I had developed over the years of lifting. From the very beginning, Hamoon was extremely attentive to my concerns. He tailored my program to my body’s needs, carefully assessing how I moved, identifying imbalances, and addressing them with precision and great attention to detail. We focused on proper mechanics, stability, mobility, and strength in a way that felt intentional and structured. Over time, I began noticing significant improvements in my movement, reduced stiffness, and increased overall mobility. One thing I truly appreciate about Hamoon is his depth of knowledge and commitment to continuous learning. It’s clear he’s always refining his craft, and that dedication shows in the quality of coaching he provides. As my foundation improved, I decided to transition into the group classes to change up my training environment. The classes are welcoming, motivating, and well-structured. The energy is positive, and the coaching remains just as attentive even in a group setting. I work a physically active job, and I’ve noticed that my overall movement and strength have improved in ways that directly translate into my daily life. Lastly, if you’re dealing with old injuries or movement issues, or if you want to train smarter and harder, I highly recommend training here, especially with Hamoon.

I’ve been training at Pure Function Fitness for a little while now, and right away I joined their group classes (they also offer private sessions, but I wanted the group vibe). At first I wasn’t sure what to expect because I’ve always done HIIT and was used to workouts that just leave you breathless. But the classes here introduced me to a completely different level of training. I’ve been taking Core & Stability, Strength & Conditioning, and TRX, and honestly every single class has so much to offer. Working with Hamoon and his team has shown me that real fitness isn’t just about lifting heavy weights or pushing until you can’t breathe. It’s about control, proper form, and understanding exactly which muscles you’re targeting. They make sure you’re doing every movement correctly — they don’t just spend 45 minutes next to you, they’re actually coaching. I’ve been to many gyms, even semi-private ones, and none of them paid attention the way this team does. At Pure Function, after all these years, I finally learned what proper posture, breathing, and intentional movement really mean. This place genuinely changed my perspective on what a good workout feels like. So grateful I joined. 100% recommend.

I had a great experience with private training at Pure Function Fitness with the owner, Hamoon, and Daniel. The sessions are caring, well-structured, and thoughtfully programmed. I really appreciate the focus on strength and mobility, and how everything is designed to help me progress without injury. Highly recommend if you want smart, safe, effective training

Come ready for a great workout, because the staff at Pure Function are amazing at what they do. I decided to give Pure Function a try, and I’m so glad I did. Hamoon and Joanah are absolutely wonderful. They really listen to what you and your body need, and they tailor the workouts accordingly. In just a short time, I’ve increased muscle mass, lost fat, and I’m looking noticeably leaner. Hamoon helped me improve my form, which was my number one concern. Not only are they skilled trainers, but they’re also kind, genuine human beings. I truly have nothing but good things to say about them. Highly recommend!

I have back pain, and Pure Function has been very helpful. The coaches pay close attention to posture and make sure every exercise is done with correct form. This really helps make the workouts safe and beneficial. The staff is supportive and knowledgeable, and I felt well taken care of. I would definitely recommend Pure Function.

I had a wonderful experience at the Pure Function workshop! The session was very informative, well-organized, and truly helpful. The instructors were knowledgeable, friendly, and made everything easy to understand. I also really appreciated the positive and welcoming atmosphere — it felt motivating and inspiring. Highly recommend to anyone looking to learn and improve their fitness journey!

Amazing atmosphere, clean gym, professional and kind trainers! It's a hidden gem, 10/10!

Pure Function Fitness Center is truly something special. Hamoon has created an environment that's welcoming, motivating, and thoughtfully designed for real results. You don't feel like just another client here--Hamoon takes the time to understand your goals and tailors everything to your body and lifestyle. As someone who was initially a bit intimidated by gyms, I felt completely comfortable from day one. Hamoon's knowledge, patience, and encouragement make such a difference. I've become stronger, more confident, and actually look forward to my workouts now! If you're looking for a personal, professional, and positive space to improve your fitness, I can't recommend Pure Function enough. Thank you, Hamoon!

Communication,quality,professional Great place! They help me recover from my lower back injury Highly recommend

I've been going to Pure Function for over two years now, and I seriously love this place. I originally started because of lower back pain as I have two bulging discs, and working with Josh has made such a huge difference. He's super knowledgeable, and keeps things fun and challenging in the best way. I'm not only pain-free, but stronger and more confident than ever. Also a big shoutout to Hamoon! He's incredibly supportive. You can tell he genuinely cares about everyone who walks through the door. The vibe here is chill and welcoming, a rare quality for a fitness center in Los Angeles. No egos, just good people and smart training. Highly recommend!

I've seen numerous massage therapists, chiropractors. and physical therapists over the years for back, hip, and knee pain.  While I've been able to find short-term pain relief through these modalities, none have been able to help me understand my condition, why it is happening, and how to fix it.  For me, Hamoon has been a godsend.  The best way I can describe Hamoon is that is a human body engineer.  He has a relentless passion for what he does and he's constantly challenging himself and refining my treatment plan.  If you have any long standing pain like I have, I highly recommend you make an appointment with Hamoon and see the magic for yourself!

Hamoon and the staff are very knowledgeable and motivating when it came to pain management and corrective exercises. Since joining, my strength and mobility has improved ALOT. They're great at finding the imbalance and strengthening a specific area to improve stability. If you want to see real improvements, pure function won't let you down

This place is amazing from top to bottom. First off, Hamoon, is an amazing owner and trainer. He has endless amounts of positivity and encouragement flowing out of him! He is also extremely knowledgeable. My first consultation there was extremely thorough. I was coming in because I had basically been sedentary during Lockdown and finding I couldn't get back to regular workouts like before. I had also hurt my hamstring, and had a weird wrist issue that I couldn't seem to figure out. What I love about Pure Function is the focus is on foundation. I have trained with Hamoon and Tina and they are both so so so helpful, encouraging and challenging. They want to make sure you are doing the exercises correctly, but they also want you to get a solid workout. Now, I'm athletic and I had done years of HIIT classes (pre pandemic) and lifting before, but I hadn't ever been told that some of my form was just a little bit off which was probably why sometimes I'd hurt myself without knowing why. Especially in classes where you're going from station to station and exercise to exercise quite quickly. We got my foundation solidified in phase 1 then moved on to lifting heavier weights etc. The point is, you get the personalized attention you need. Tina has helped me SO much with my workouts. I'm feeling stronger by the day and my wrist , which I thought was an injury, was actually more along the lines of being weak and not flexible. It feels so much better now just from target stretching and wrist exercises! Also, The gym is immaculate and there is parking in the back (or meters) so it's easy. Sahar is also amazing and kind - this is who you talk to when you set up packages or scheduling. She is so accommodating. This business itself is run so well because you are so welcomed here as a client and completely taken care of.

Pure Function Fitness Center is a fantastic private gym!! Hamoon (my trainer) is super friendly and interested in improving your fitness level no matter what your fitness level is. I really like how he gives me tips to get the most out of every workout. I'm training with me for less than a year, and I can see a significant change in my energy level and body form. The studio is super clean, and they disinfect everything after each training session. They offer a free assessment session, which is very useful to get to know your fitness level.

I can't not say enough. !! I been looking for personal training my criteria were.. Lots of experience Knowledge preventing future injuries I just finish Physical Therapy Wow I was not disappointed. TRX is amazing!!! Thank you

This place is awesome. I've gone a few times now and each time have felt it the next day in the best possible way. Hamoon is extremely personable and his passion is evident from the moment you meet him. I play a ton of volleyball and already feel like the sessions here have contributed to my mobility and reduced likelihood of injury.

Hamoon have been training me for the past 6 months. He is an expert in human biomechanics and corrective exercise. Every single session is different and educative. I love the fact that he teaches me how to have the right posture and also the way he pushes me every time I get in there.

Professional, expert, committed and friendly! I'm talking about Hamoon, the Pure Function's owner. He's completely different from all fitness instructors I had so far. He analyzes your body, listens to your needs, and design your workout plan accordingly with the latest updates of the industry. He is 100% committed not only to change your body, but also to change your life style to the best.

As a guy in his 40's I have had a real problem getting the right kind of work out to fit my lifestyle, however Hamoon designs the program to maximize all my functional sport needs. This gym also has the best state of the art equipment, that makes me feel I'm getting the best of the best.

You will LOVE this place if you like a private area with your personal trainer who gives you full attention. We were a group of four and felt very comfortable. I have a damaged shoulder and knee. Hamoon modified my excercises while we were all working out together. I felt very comfortable and trusted him because he explained everything step by step and was observing my movements. At least schedule your assessment with him even if you don't want to go there. His assessment is very different from the ones you get at regular gyms. HIGHLY RECOMMEND

The location is great, all the equipment is new and super cool. Hammon is so knowledgeable, kind and encouraging to workout hard. I had the best workout ever. Super sore now. See you Saturday. AR.

Hamoon at Pure Function is an amazing and caring trainer! During my initial session he took me through a thorough assessment and worked with me to define my goals. I set what I had initially thought to be a "dream" goal, and 3 months later I actually hit it! When I first started I thought I would dread going and have to force myself. I used to workout at Equinox but never felt I was getting good training guidance and results. I no longer have to force myself to go to the gym. Hamoon works with my schedule to book times that easily fit into my routine. I genuinely look forward to and enjoy coming here! I come 3 times a week. I feel so much better after I workout and love how my body looks!

love this gym! Hamoon is such a knowledgeable and motivating trainer. The workouts are always super challenging and diverse, so you never plateau. Plus, it's really clean and all the equipment is brand new. i love design and general vibe in addition to the killer workouts!

Hamoon knows it too well! If you don't want to damage your body and get your dream body, this is the place to go. It's great to learn the correct motions. His assessment of my body was spot on. Enjoyed working out very much. Highly recommend him.

Phenomenal fitness center run by a high level trainer! This place is not like your average gym where you tell them what you want and they work you out hard. This place gives you an hour assessment of what your weaknesses are, what your goals are, what your nutrition is like. Then a well detailed plan with different phases is laid out for you to achieve your goals. I'm a high level athlete and just after 2 weeks of training with intention, I noticed the improvement in performance. They will even help you with recovery techniques, and how to help injuries heal faster. I also love that they have a machine that measures not just your weight but other important performance indicators like body fat percentage. The trainer is also very hands on with correcting form and ensuring you are working and engaging the right muscle group. For years, I found ways to cheat and let my stronger muscle group take over. He will not just correct your form, he takes the time to explain the whole movement and why. I highly recommend this place. Forget the gimmicky group classes like F45 and Orange Theory, or the big gyms like LA Fitness and Equinox. This place is how true high level athletes and movers train and I highly recommend it.

Great choice for anyone who is looking for a result-oriented and knowledgeable trainer. He not only helps you get physical results, he also helps with your mentality to get there. Not everyone can push me to my limits, but Hamoon can quickly realize your fitness level and push you to the next level.

It was a great experience working out here . The trainer 'Hamoon ' was very helpful and he paid attention to all of us in thE session to do the exercises correctly . I'm motivated more now to work on my body to make it the shape I want . Highly recommend it if you want to make your favorite desired shape .

I have been training at Pure Function with Gabriel for 3 months and I can honestly say I feel incredible. Before I started I was an out of shape husband and father with a previous background as a Personal Trainer. As the years crept by so did my inactivity level. Over time I felt tired, lazy and unhealthy. Now I feel STRONG, HEALTHY, POWERFUL and FIT. The work outs are carefully tailored for my age, fitness level and goals. We do HIT and TRX workouts coupled with full body movements with light weights. The emphasis is on MOVEMENT, FUNCTION, and FITNESS. There is a lot of stretching before, during and after workouts to ensure mobility and limit injuries. The environment is positive, uplifting and energizing. Great clean studio with great music, and reasonable personal training rates. The equipment is high end equipment and the trainers are INCREDIBLE!!! PURE FUNCTION gets it done. Thanks Gabe!!!

Hands, this a truly great place to work out. hamoon has a deep knowledge of how muscle should work. he is fantastic at identifying and adjusting incorrect form to absolutely maximize outcomes. i wish i had discovered him sooner. the very best! highly recommend training with him.

I absolutely love working out with Hamoon. HE KNOWS WHAT HE IS TALKING ABOUT!!! I used to have a personal trainer who ended up damaging my joints by not knowing what the heck he was talking about. Getting certified is not enough. You need to know human anatomy very well to not damage people. He knows it very well. The setting is private and that makes me feel comfortable. I don't have to wait in line or have others watching me. And most importantly I don't have strangers talking to my personal trainer about my physical condition and how much it has improved. Yes, it has happened. Love this place

Hamoon are trainer is very caring and friendly. He has encouraged and challenged me the last two years. I am in the best shape I have been in by going to my weekly trainings. Hamoon is invested and knowledgeable as a trainer. I will never go to anyone else.

I used to just work out by myself multiple times per week, but after a year of working out I felt I had plateaued. I figured I needed a trainer, but finding a good personal trainer is extremely difficult. I'm so lucky to have found Hamoon. After just a few months with him and trusting his process, I already started to see results. He's extremely knowledgeable about his craft, and is so dedicated to helping you reach your goals. I highly recommend Hamoon from the bottom of my heart. Thanks Hamoon!!!
