The concept is great. I went there for 1 year. I did everything they said for 6 months. You know how much weight I lost in 1 year? 0lbs. The trainers pretend they care but I always had to reach out to them for updates, lab tests, etc. Also, they charge you without letting you know in advance. I again had to reach out and tell them "hey at least give me a heads up, it's a lot of money to just get charged rabdomly". When I quit no one reached out to me. Nobody cared but yet when I was paying they all loved me. I still one session but once my trainer found out I wasn't renewing he asked me if I could make my last session day a certain day, I said I couldn't, never heard again from him or anyone at Stark. Really disappointed considering how much money I spent on nothing. I would post a picture with my review but I'm still fat. read more

Awesome place to come get fit, learn about your nutrition and health. It's like a one-stop shop! They have a chiro on-site, a naturopathic doctor and fully knowledgeable trainers that almost become like family. I love how you get welcomed every time you walk in by the receptionist and the staff inside the gym. I also love how they do a complete blood panel and the most important thing I loved is the food panel which shows your sensitives. This was truly an eye opener because once you recognize what sensitivities you have, you're able to change your diet to help reach your heath/fitness goals. I come here twice a week and love it! read more

After many gyms and personal trainers I finally found a gym that really helps me with my personal physic. I have struggled with anxiety for the past three years after signing up and putting in hard work I've seen a huge difference, both physically and mentally! Drew Valentine and Jon Luong are the best at what they do! They are amazing trainers! They really care and are very diligent in what they do. Dr. Firas is knowledgeable and attentive and helped overcome my anxiety!!! If you're quick results I definitely recommend this gym. read more

A comprehensive place to train and get fit. You get a customized plan and all the trainers I've worked with are fantastic! Whether you are new to working out or a vet, I think you'll learn new things. read more

Stark has been and still is "the coolest gym in America" I've been a client since 2012 and keep coming back for more! You are not going to find another gym with a more complete approach to health and fitness. They not only have the BEST trainers (Rob) but they provide lots of other services that augment your training. I've cancelled my membership to 24hr Fitness because I couldn't imagine working out anywhere else.......thanks Todd :-) read more

Stark is the best gym ever to go to. I love going to stark because I get to see my trainer Jasmine.

Possibly the best overall program for good health, as well as mental and physical fitness.

I was refereed to Stark by a business colleague that has seen amazing results. I originally came in for a trainer (who is exceptional!) and what I got was a family who takes a 360 degree approach to my health. Food sensitivities, nutrition balancing, mechanical disorders, and tailored workouts. It's a very high tech approach which involves not only my trainer-coach-"extraordinaire" but an entire staff of professionals. There is real accountability now BUT with realistic expectations. Changing your life is never easy but with Stark they seem to have a "blueprint" to achieving whatever fitness goal you're after. A+ read more

Brad (co-owner of Stark) has created a fitness facility for those who are SERIOUS about a lifestyle change. The methods are not fads or simple, quick fixes, but real, honest, and hard. The results depend on whether or not you can be committed not just to getting to a size 2 or benching 300 pounds, but to ultimately changing your life. I love the trainers and everyone really is committed to helping you be the best you can possibly be... inside and outside of the gym. Pros: 1. Everything is NEW. 2. The personalized showers make it easy for me to get in a good workout and get ready for work at the same location. 3. The personalized attention to detail Brad has at assessing your hormones, body fat, and health has helped me so much. Cons: 1. You can't schedule an appointment unless you call while the secretary is there. 2. You are not always guaranteed the same trainer. 3. You can't access the appointment center online. read more

Great workout! Took the Met Con class with Geoff for our first class and even Nam loved it (and he hates group classes!). They are super duper nice from the moment you step through the doors to the moment you leave. I was excited to come here from the reviews, but it's a totally different feeling once you've actually taken a class. It's hard and you'll sweat, but it's fun! New to me were the sled pulls and battle ropes. Intense and I could definitely feel my muscles working! :) Geoff and the other instructors would watch our form and make sure we were doing things correctly. That's always a biggie for me because I don't want to injure myself working out, and hope the teachers are attentive enough to notice if I'm dong something wrong. After the class was over, Geoff showed Nam how to work with/flip Strongman tires. Really nice guy. We had Tyler another time and he killed us! Really challenging workout with a sled push relay to finish it off. Ahh! I couldn't walk after, but I definitely felt stronger and accomplished! :P Again, instructor was encouraging and pumped you up to work your best! I can see why this place is so popular and will keep coming back! read more

I first heard about Stark from someone I have great respect for. Though I was in good shape before working with Stark (5 days a week at a fancy gym, 3 days with a trainer), I figured I would at least go check out their operation. I was immediately impressed with their attention to my specific goals, and current physical condition. When the initial assessment was explained to me, I knew they were professionals in a league of their own. Another aspect of Stark which impressed me was that they regularly assess my progress. I can see the numbers, and I know exactly where I am. After only a few short weeks, I was noticeably leaner, stronger, had much more energy, and slept better than I had in years. These were my initial goals which Stark got me to achieve, and exceed. read more

I went to Dr. Justin for my shoulder after physical therapy didn't work and he got me back to normal in four visits. Then I sprained my ankle and he's been helping me recover from that. It's made my recovery go by so much faster and he has helped me so much. He knows what he's talking about and has answered every question we've had. My overall experience there has been amazing, the receptionist is so sweet and they are very personal. read more

If you are looking for a place that will change your body, this is it! There are many personal training facilities out there, but this one is different. You will get the actual PERSONAL attention that you deserve. The workouts are designed for your body and your ability. This place will challenge you, motivate you, strengthen you, and keep you on your toes. I love working out here because the trainers are knowledgeable and encouraging and the workouts change every month! All you need is dedication and the results will come. The workouts are created for you, the diet is created for you, and the supplements are prescribed for you. Not everyone will be on the exact same program. This is why the results will happen if you train at Stark. Time can be as minimal as 2 workouts a week only 45 minute workouts. read more

I have been seeing Dr. Jay for about two months now. He has helped me finally begin to put an end to my migraines that have affected my life for over 13 years. The Stark facility is pristine and outstanding, yet still small and not at all overwhelming. If you want a personal trainer, need some rehab, or finally want to put an end to your pain go to Stark!!! They are stellar :) read more

high quality focused personal trainer with extras. you can get your chiro work done there. They have a cryo machine to help with inflammation. they have a naturopath who puts you thru a ton of tests to help you out. They are legitimately a 360 degree experience. The staff is very knowledgeable. Plus, they change up your work out routine regularly... and they stretch you out. Todd Tyler & Brian have created a culture that makes people want to come back. It is unlike any gym I have ever worked out at. I have been going there since Aug 2016. read more

I've been treated with Justin years before but came in today completely sour and debilitated from a neck injury. I teach yoga full-time, so not being able to move = SUCKS!! Justin listened to me rant about how upset I was over this injury, being extremely compassionate and sensitive to my pain. Then he worked his magic. My pain is not gone but this is the first thing that has brought me relief in 4 days. I can at least move again! read more

I've been training at Stark for almost 60 days and the knowledge base of the trainers at this gym surpasses all other gyms that I have ever been too. Their methods are scientifically supported for the quickest results based on your specific needs. I personally dropped 3% body fat in 3 weeks after having worked out on a constant bases for years with just stable results. I highly recommend this training facility for anyone who is looking for solid results that will be long lasting. read more

When I went to one of their free fit back clinics about a week ago, boy was I impressed! I thought, I'm definitely going to sign up for this so I made an appointment for the free body analysis. There was some confusion on my appointment and it was canceled when I arrived... I was very upset! I emailed Dr. Todd and told him about my situation. He promptly emailed me back and apologized and asked if there was anything he could do to make it up to me. He listened to my complaint and treated me with dignity. I truly appreciate that he took time out of his day to handle my situation and that he wanted to make sure that in the end I was happy. Thanks for caring Dr. Todd!! read more

Wow, where to begin. Starting with the care, Dr. Jay has been the most thorough and effective chiropractor I have ever received treatment from. From the intake process, to adjustments, to discussion and overall time spent, I am incredibly pleased. The most incredible outcome has been the resolution of a severe case of TMJ. In my first treatment, Dr. Jay adjusted my jaw - and I am not experiencing popping or clicking for the first time in almost 15 years. And, my neck is improving with every treatment. I am very thankful for the quality of the care and total experience. Now I'm looking into the training side of things - to try to achieve total wellness. Thank you Dr. Jay! read more

Dr. Jason Amstutz and his team completely set the bar for Chiropractic and Rehabilitation Treatment. I can honestly say I walk out of this office standing taller, more educated and always feeling better. Suffering with Scoliosis since a very young age has caused severe pain and alignment issues. The corrections, adjustments and knowledge I have been given by Dr. Amstutz is hands down the first and only facility that has given me true relief and hope for a pain free life. As good as it gets doesn't really suffice in my opinion. read more

Doctor Justin is great. He is very knowledgable and kind. He knows what he is doing. He employs active reflex therapy (I think that's what it's called) where they stretch the muscles while working on it. I have seen great improvement for my sore muscles from work and recommend him to a lot of people. If you have sore muscles do not hesitate to go to Doctor Justin. He really cares to see you better and loves what he does. Which are both important qualities when I choose to see someone. read more

This place is great! The female trainer was professional, knowledgeable with a really positive attitude ( and this at 6AM in the morning.) Lucky for me on the day I went to class I just happen to be the only one to show up, so basically I received a personal training session. You might think that the trainer would of had a bad attitude getting out of bed so early in the morning for just one person to show up for class...but not the case. This place is cool, clean, good music and great trainers. Best kept secret in town.... Do something good for yourself and give this place a try. A+ read more

It's super expensive and they keep changing all the rules. Was a dedicated member but they kept changing the pricing and my workout times. The constant measuring and supplements are a time waster and another ploy to get more money out of you. The trainers are good but the management isn't. There are many better choices out there. Unless your a professional athlete. read more

STARK is awesome! The best place in OC to get fit and have fun while doing it :) Not only is the brand new facility great, but the trainers there are motivating & they make it fun to be there! Before going to STARK, my body fat was 22% and in one month it is now 17% & I lost 7 pounds already! I couldn't be happier!! read more

STARK is by far the best place to get in shape! I used to be a swimmer and gained a bit of weight once I had quit but when I went to STARK I lost 4% body fat in one month!!! The trainers are very inspiring and motivating and not bad to look at...which makes it fun!!! This gym is a great place for anyone trying to be healthy and fit! LOVE STARK!! read more

Thank you Stark Fitness....because of u & your awesome workouts & training this 54 year old rocked it at our annual work softball tournament yesterday....I showed up for work today feeling great....compared to all the other employees who were sore & complained of all kinds of sore limbs...but not Me!!!! I could kiss you all!!!!!! Thanks again... See you on Monday morning.... read more

I'm giving five stars for Dr. Jon Gundlach at Stark in Irvine. I met Dr. Jon back in 2009, when I was training for an Ironman. I had been dealing with a serious calf injury for nearly two years, and I had been to see doctors and physical therapists up the wazoo. I had mulitple x-rays, MRIs, and ultrasounds. No one could figure out what was wrong with my swollen calf. It hurt to walk on, much less bike or run on; I could only find relief by wearing a surgical stocking close to 24 hours a day. And then I went to see Dr. Jon for a back issue. While he worked on my back, I told him about my leg problem. After my second visit to Dr. Jon, my leg was pain-free. I was amazed and overjoyed and so incredibly thankful. All along I had been thinking I would need surgery, but with a bit of ART (active release therapy), Dr. Jon completely, totally, utterly fixed my leg. I have had zero issues with my calf since then. I still see Dr. Jon for various back issues from an old running injury, and he fixes me every time. I cannot say enough about his practice! If you have any pain at all, I highly, highly recommend you make an appointment to see Dr. Jon at Stark. A couple visits, and you'll feel so much better. Going to see Dr. Jon just might give you your life back! read more

Hands down the best gym I have been around. I have been coming to Stark for about 2 months now and the results have been amazing. I'm 27 and have been dealing with back problems since I was 22. I haven't been this strong and pain free since before my injury back in 2011. Their attention to detail in incredible and they are very professional and courteous. They make you feel welcome. read more

These trainers are wonderful! What a great group of people whom work together for the greater good of the client. I was pleasantly surprised by everyones' demeanor and friendliness. Yes, they are there for you, however, they just happen to be a great group of people to be around. They care about results. I thought I was in decent shape before signing up at Stark and am now excited to see what my body has been able to do. I do the Svelte womens class 3x/week and am seeing great results. Slim and toned - just what a girl wants! read more

Where do i begin.... lets start exactly 1 year ago. I was getting married in exactly 2 months and I was working out 6 to 7 days a week, sometimes 2-3 hours a day. whether it was back to back spin classes, yoga, pilates or just plain running in circles, I was doing it. Skinny right? ya not so much. Come to find out all the working out I was doing got me absolutely no where and was having reverse effects on me and my body. Stark help me realize that. They put me on a very specific customized diet, prescribed my supplements and had me training hard but only 3 days a week! when they told me my Workout schedule i was like...oh ya so I'm going to lose weight working out less...and no cardio...what were they thinking?! Now fast forward 1 year later and I'm in the best shape of my life! I'm down almost 20lbs and I have toned and tightened my body in places that i actually gave up on. Now my wedding dress is 2 sizes too big...hilarious. This has been the most amazing transformation and Im not stoping yet. Every month they change your program, new diet, new supplements and new workouts. Which means less and less clothing Ill be wearing to the beach! This is not a gym with personal trainers, this is not crossfit where you compete throwing around heavy weights with no supervision, this is a training center with some of the most amazing, educated trainers in the business, on staff doctor and muscle specialist, and most of all its family. This place has all the missing pieces to every program that has failed. And last but not least, Jesse Gawinske, my trainer, ROCKS! Im so thankful to have found Stark and I know ill be a part of this program for a long time. read more

Oh stark... where do I even begin!? I LOVE this place! From the second you walk in- Tamara is an absolute doll and ALWAYS has a big smile on her face and greets you with such a warm welcome. Not only is stark and amazing gym in which I've had awesome results from but they have become family to me. The entire staff is so knowledgable and passionate it makes working out fun! I have never been able to stick to a work out before I came to stark, and now I actually get excited on my way in. Each work out is customized for their clients depending to what goals they wish to achieve. For me it was more defined arms and a healthier lifestyle- which I have absolutely achieved- I can't say enough good things about this awesome place, you definitely get what you pay for- oh yeah, and a yummy shake after your workout! Thank you STARK- I love all of you guys! read more

This gym literally saved my life!!! I needed to lose some visceral fat, the fat around ur organs that you are supposed to have in order to protect them; which is like super hard to do, in order to get a surgery I needed to pretty much live. I went to the wonderful people at Stark and asked them to do the impossible, help me lose the fat while on a very restricted diet, physically very weak after already having two very invasive surgeries in three months, and they only had six months to do it. Needless to say, I am healthy, alive, and in the best shape of my life. They encouraged, pushed, and at times even carried me thru the hardest time of my life. My surgeon was astonished by my recovery from my 4 surgeries. he has been the top surgeon in his field for 17 years, and has never seen a patient bounce back like i have. You would be crazy, I mean absolutely looney tunes, to not train at Stark. They give you the tools to live a healthier and happier life, and support you while achieving any and all goals you set for yourself, even if they are impossible. I have learned that with tremendous and unconditional support, you can achieve anything you set your mind too. And I learned this from the people at Stark. read more

I joined Stark back in 2010 in preparation for my 40th birthday. I always thought that I was in great shape until I actually saw (in B/W) what my body fat was compared to my weight. I then realized that as i am getting older, I needed to do something fast about it! The beauty of Stark, is that they train you and also teach you how to eat properly. The trainers are top notch and very well educated, as they are always learning what is new and innovative and are constantly taking classes by some well known folks in the industry. They also taught me that DIET is everything, not just showing up for workouts. They also have some great chiropractors and physical therapists on hand. Without that service, I would not be where I am today. I was originally 175 lbs and 24% body fat and am now am down to 155 lbs and 6% body fat! A truly magnificent transformation to a guy like me. I have a busy business life, just like everyone else, but through Stark's amazing programs, client interaction, well knowledgable staff, and awesome atmosphere, I am able to reach all of my goals. I strongly recommend Stark to anyone who really wants to improve their way of life. They truly are life savers! read more

Love this gym, my daughter came here last year & what a difference it made for her... Trainers & front desk so friendly always greeting you with a warm smile....& now I brought my son & he loved it & his trainer Brian, made him feel welcomed too... read more

I started going to Stark last year to prepare for my wedding.. Little did I know if would be a complete life changer for me. For someone who hated everything about gyms, I was so reluctant to go in. As soon as I started my training though, my fears & intimidation about gyms faded. The team at Stark is not only professional, knowledgable but the most inspiring group of people I've been around. Their training programs are challenging & definitely help you achieve your goals. Obviously you have to do your part & keep a consistent schedule & stick with their diet programs. I'm a few months away from my wedding now but going to Stark has developed to be so much more than getting in shape for the wedding.. It's about feeling amazing every day because of the amount of energy I have now, leading a balanced & healthy diet & surrounding myself with motivational people. I couldn't express more gratitude to these trainers especially Chelsea, who pushes me everyday to achieve my goals. read more

When I was ready to make a change, Stark was right there. Ready to customize a workout program for my skill level, ready to deliver a food plan that was customized for me and a team of associates who are all ready to assist. The Stark team is consistent, dedicated and focused on making a difference for each and every customer. Workouts that challenge me, make me sweat at every workout and make each workout rewarding. Seeing the difference in my body makeup, make each and every workout worth it! Don't wait! Go for what you want with a support team that works with you. read more

Dr. Jon at Stark has changed my life! I'd suffered from months of chronic sciatic pain which left me afraid to move let alone workout. I felt like all I could manage was to sit or lie down and not do much activity for fear of the painful shocks running down my leg. I knew I couldn't go on like this since my inactivity was really just making the problem worse. After a friend highly recommended Dr. Jon I gave him a try. I had never tried ART before and was a little nervous. The first day I saw him was my last day with pain - I'm no longer afraid to move and have resumed my normal workouts and then some! He's also worked on loosening up my neck/jaw (the constant headaches are gone) and my forearms/wrists (I can now type for hours without any arm pain). I can't recommend Dr. Jon enough - whether you have an old injury or something acute, don't waste any more time living with pain and get in to see Dr. Jon! read more
