After visiting the local boxes in the area and doing a trial workout (Costa mesa, Irvine, Tustin), I ended up here at Insanity. My first trial workout with Dave was a beast, he put me through the "Baseline" WOD, after comparing my time to the white board, it really let me know these people are athletes. Taking a look around the gym, checking out the website and researching past WODs, meeting some of the members, and talking prices, I felt Insanity was the best mix of space, quality of equipment, quality of instructors, community, difficulty of workouts, flexibility of schedule, and price. The box is huge, smaller than Costa Mesa, but larger than Irvine and Tustin. They have shower facilities, a huge plus to working out in the morning and jamming to work. They also have one of the best schedules, 4 morning classes, 1 lunchtime class, and 4 evening classes. Also, you do not have to go online and reserve a spot in class, just show up. Not feeling the 6am workout and wanna hit the 7am? Get off early from work and wanna hit the 4:30pm class? Go right ahead! I signed up for the Essentials class last week and just finished my first real WOD with the normal class today and it was amazing. The athletes are real supportive, and although the class was over 15 people, there were 3 coaches present watching the room, so you will be corrected if your form suffers. Bottom line: this is an awesome place to train, no egos, no meatheads, no "bros", just people looking to work hard. Can't wait for my first muscle up!!! read more

If only I could relocate this Crossfit box to my area, that would be so awesome!! I had to spend several weeks in the Irvine area due to work commitments and considered myself lucky to be near this specific Crossfit.....what a great experience! The coaches are all amazing (especially Dave and Mara!) and I learned a lot. I noticed significant improvements in my lifting abilities/technique and appreciated all the feedback I got while I was there. I can't say the same for many other Crossfit boxes and I have been to a fair share since I travel frequently for work. If you're lucky enough to live near this place and you're looking for challenging workouts with encouraging coaches then trust me, you won't be disappointed. Everyone there was super friendly and made me feel at home....is there a way to join workouts remotely via the web?! haha....I wish. Crossfit Insanity definitely sets the high standards that I would look for in a Crossfit facility, other places could learn a lot from this place! read more

I joined CrossFit Insanity when I moved to the area. The coaches (Dave and Mike) are phenomenal. During class, they guide you through each movement, while giving individualize feedback and attention. The music is great. The community is energizing and welcoming. I'm thankful that I found them in the short time I was in Irvine. They helped me develop my love for working out, training hard and lifting heavy. It's the best CrossFit box! read more

I had a membership here for several months, but due to an injury I had at work, I have not been able to come back. This place was fun and was a great place to supplement my other workouts. I recommend this place for everyone from all different fitness levels read more

I've been coming here for 6 months and can't say enough good things about this gym. The trainers are great, the people are great, and the overall atmosphere keeps you coming back. Thanks to this gym I'm in the best shape I've ever been in. read more

8 months in and I'm addicted. The coaches are great and they really work with you to make sure you get the best out of your workouts. Everyone is friendly and encouraging. Perfect for all fitness levels. read more

I love this gym. You can waste time lifting weights at 24 hour fitness or equinox or you can go to CrossFit Insanity and see results!!! I've been working out here for 6 months now and my body has transformed. Their workout is tough but doable. People that work there are really cool, and I think since their classes are so small, they are able top attention to your individual needs and suggests variations appropriate for different people. Price is also very reasonable Highly recommend. read more

I have nothing but great things to say about this place! The coaches are welcoming, friendly, knowledgable, and funny. The other members are competitive but encouraging, and it's so easy to make friends. The workouts are challenging, but you always get through them. I've been a member for a little over a year, and I'm so sad I have to leave because I'm moving. read more

I've worked out a several crossfit gyms due to moving around a lot, and I can safely say from my experience this is my favorite box ever. The community is wonderful, they dedicate and inordinate amount of time to having good form/reducing risk of injury, and I have made serious improvements on all my lifts. Definitely would recommend. Also one of the gym puppies smells like Jesus, so there's that. read more

Beware! Anyone who is looking to join Crossfit Insanity in Irvine needs to read this. I signed a 3 month contract which I fulfilled. I sent an email and verbally told the business owners that I was canceling my membership 2 weeks prior to the end date. 3 months later, I realized Crossfit Insanity had continued to charge my credit card monthly. When I called to ask for a refund since I clearly had an email chain showing I had canceled my membership, I was told by Dave, the owner of the club, that there was no way he could refund my money. Their contract is written in a very deceitful way explaining that "after all contracts expire the contract will automatically renew". Be cautious, I don't want the same thing to happen to you. I would suggest finding another gym where the trainers actually care about their clients and aren't there just to take their money. read more

Great workout but a bit steep for drop ins. For those outta Towners, $20 just for the work out. Usually I pay $20-$25 for the work out and walk away with a t-shirt, but not the case here. read more

Dave was so welcoming and the programming was challenging. We did three classes while we were in town. I would definitely go back if we were in town! I would be a member here if I lived here. Go on and try it out. You won't regret it! read more

Crossfit Insanity takes working out to another level! The trainers there are energetic and passionate about crossfit and it shows in the diverse workouts we do each and every day! If you are looking to get in shape and see results fast, visit them in Irvine! read more

An amazing crossfit gym, they truly make crossfit feasable to anyone. They are very personal and put attention to each person in the class. They truly take the time to get to know you strengths and help you. Crossfit Insanity custom tailored each workout to meet my goal (weight loss). Now that I've lost significant weight, I have become more interested in the heavier lifting, I'm truly enjoying myself. Be open and honest if you have any lingering injuries; they will help you out. I have Chronic Shoulder Instability (it pops out and goes back in with certain movements). I have not have my shoulder slip since I did my 30-day trial. Thank you, I'm glad I decided to work through the pain because now I can move my shoulder like in 21 again! read more

The best part about this box is the sense of community. Everyone hangs out together inside and outside the gym. It's a real family atmosphere. The coaches really know what they're talking about. They want you to get better and they push you every time you step on the floor. I came from an endurance sport background and wanted to do crossfit as part of an off season strength training. Crossfit has improved all aspects of what I need: strength, conditioning, core, mental toughness. If you're asking yourself whether or not you should do this, the better question to ask yourself is have you challenged yourself recently. read more

Place is dope! Super friendly staff that pay attention to what your doing. This place will give you an intense workout and help you shed pounds off read more

Some of the best coaching, programming and community of athletes I've been exposed to. The coaches are more than qualified with several reputable certifications beyond Crossfit certs too. read more

Great for all levels of fitness. They are very understanding and encouraging. Great culture of motivation.

CrossFit gyms have been popping up everywhere but the programming and coaches are what make this facility superior. I was the girl always doing the same spin class and ab workout, wondering when my six-pack would make an appearance. Apparently, it was waiting for me at this box. I am more toned and tight than I have ever been. But more importantly than aesthetics, I feel better and stronger than I ever have. I can lift weights I never imagined, do pull ups, sprint, and much more. I also have my very own CrossFit family pushing me to be better and partying with me on weekends. I am a CF Insanity convert -- didn't hesitate to cancel my much cheaper 24-hour fitness membership. It doesn't compare to the results I am getting now. read more

I started CrossFit a over a year ago when my sister and her bf convinced me to try it back east. I loved the workouts and the family feel their box had. When I looked for a place to try out here I found insanity because of its vicinity to my job. My first day there Aaron threw me into a workout and had my muscles aching, my lungs burning and me wishing I had never set foot in the place, let alone ever again. Needless to say I went back and have been there 5 days a week ever since. Prior to visiting this box I hated lifting weights, despised running and didn't want to do any physical activity besides beer league softball twice a week which was "working out" to me. Now I look forward to seeing what challenging and fun workout I get to do as well as encourage others through. This place has a great team and family atmosphere from the others in class cheering you in to your last rep or seeing Dave and Grayson walking around coaching and instructing. If you are looking for a place with challenging workouts, inviting people and a way to get healthy in the process this is the place for you. read more

Crossfit Insanity really deserves 5 Stars yet its my favorite place to get a powerful workout in and I don't want it getting too crowded. The variety of functional exercises has me feeling better at 40 than I did in my 20's. starting at 6 gets me home by 7:15 when everyone else is waking up. The coaches and members are supportive and inspiring. read more

This place is addicting! Foster and Dave are knowledgeable and amazing coaches. They fix my forms and to make sure I am doing it right or safe. This box environment is fun and welcoming. The people are friendly and encouraging, great community! My husband and I are happy to find a home box and be a member. highly recommend to give this place a try, you'll be hooked like we are. read more

I was out here for two weeks for training visiting from CrossFit Hoboken. After long days of work the crew at CrossFit Insanity made my day end perfectly. Mike Aaron and Dave are all super friendly and welcome people like myself as if I was a member. In addition the members are very approachable and make u feel at home. The programming is challenging and effective and allows for both a strength/skill component as well as a metcon. I am going to miss the crew here and I hope I get the chance to visit again! read more

I came to CFI for 7 months. I had never tried crossfit before. The first day I came to the gym I fell in love! Foster instilled a passion for this amazing sport. His energy is unmatched and he really wants what is best for all of his members. The workouts are great and you will look and feel better! They are a great support system. They pay attention to detail and form. Everyone is really friendly and very welcoming! Great place to create a support network and to even drop in! read more

Crossfit Insanity is my favorite place. Almost 2 years ago, I struggled with my fitness, so my friend recommended me to CFI. I came to CFI with no experience, and now I'm addicted to it. I feel guilty if I go less than 4days a week. All the coaches helped me through a lot, correct my form of every movement, and push me hard to get better. I lost more than 20lbs, and look fit now. For someone that struggle with losing weights, this is a place for you to go. The intensity of the work out will help you a lot. I have NO INJURY at all because all the coaches are very attentive. It's so sad for me leaving the box because I'm moving to a different city. Now I've been trying few other crossfit box, I'd say CFI has the best programs ever. Dave, Mara, and Michael are amazing coaches. They are very knowledgeable. They focus on both strength work out and the WODs. I highly recommend this place to anyone. They make my crossfit journey so much enjoyable. read more

I walked in and wanted to turn around and walk out- lol, but, I came back and fell in love with Crossfit- the vibe is welcoming and friendly and definitely supportive -I am addicted-the coaches don't let you slack either-which is what I love and need read more

I've been working out at Crossfit Insanity for about 6 weeks. The coach's are great: they puh you to lift more, go faster, and work harder, but not at the expense of form or safety. They accommodate everyone from the elite athlete (some of those guys are insane!) to the couch potato that just decided to change his/her habits. They push everyone to get better. The members are friendly and supportive. Everyone pushes each other to get that last rep and then celebrates success whether you set a new record for the box, a new PR, or just struggled to finish. I look forward to the workouts and miss them on my days off. read more

The best thing for me to say is JUST GET IN HERE! If someone told me three years ago that I'd be not only be doing crossfit, but that it would become my new hobby after doing ballet for 14 years, I would have told them to reassess who they were talking to. Since starting this sport about 2 years ago, I am amazed at what I have gotten my body and my mind to do. I never thought I'd be weightlifting, doing pull ups or handstand pushups (just to name a few things) or that I would have the guts to compete in a crossfit competition! Not only has the sport of crossfit changed my life, but my "family" at Crossfit Insanity also helped change my life and the way I view health, diet and fitness. At a time when I was at a crossroads and wasn't sure whether to stay in California or move away, one of the biggest deciding factors was that I found amazing friendships and community at CFI. Crossfit Insanity is not like all the other crossfit gyms out there. You feel as though you are getting personal training while still being in a class with your friends. The coaches watch you closely to ensure you are executing movements correctly and help you out when you need it, especially at the toughest part of the work out, the end. They help give you that extra push you need to finish it out. You also have the freedom to attend whatever class time is convenient to your schedule regardless of what day it is. Everyone is super friendly and welcoming, always! It has been through the coaching, education, programming and encouragement that has helped me tap into personal strengths I never knew were there. I am in the best shape of my life and excited to get to the gym everyday. I'm more toned that I ever thought I could be, but I love that I'm so much stronger!! Come in and drink the kool-aid. You're gonna get hooked, I know it! Oh...and Ladies, that myth that lifting weights will make you bulky? IT IS JUST A MYTH. Trust me. I used to believe it too. read more

I did CrossFit about two years ago in San Antonio and I remember getting in the best shape of my life. I was going to 210 CrossFit which was a very disciplined and friendly gym, where everyone was family. Last year I moved to Cali and was looking for the same type of environment so I tried CrossFit HB, OC CrossFit, CrossFit Garden Grove which were all good, but CFI is the best I've seen so far. I wanted something a little closer to my house so I decided to go by CFI within minutes of taking a tour of the gym and interacting with the owner Dave and a few people I felt at ease. They are very professional and each session feels like you are being trained one on one. They demonstrate all the movements and make sure that you focus on the form with each movement. The workouts are the toughest I have endured in years and I have been in the Army for 21 years so I'm no stranger to working out. If you have not tried it I highly suggest that you attend 1 class and you will be hooked. Their hours are really flexible and the class sizes vary from time to time, but its never too crowded where you don't get that one on one attention that is important when starting any fitness program. Also everyone there is constantly motivating you to do better during each workout which helps alot. What people don't get is that when you sign up for a 24 hour or LA fitness membership you are being trained by people that have half baked Certified Personal Trainers Certificates, and you have to pay them for each 30-60 minute training session plus your monthly dues. At CFI you pay one price and you have at a minimum a Certified CrossFit Level 1 Instructor teaching you every movement and guiding you to your fitness goals. These guys are serious about results and it shows by the quality of the members. If you ask me the monthly fee is very reasonable when you consider the comprehensive fitness package they provide. read more

Drop in rate is very palatable. Workouts are very familiar to me with a solid warmup, strength component, and WOD. I worked out here twice and the group was relatively welcoming and the workout good. Would highly recommend. read more

I am a 72 year old lady that joined in May 2013. Mara, my trainer, plus my Crossfit Insanity workout have changed my life. I feel wonderful. Mara always adds a new exercise so I don't get bored. And I have't been sore once. read more

I practiced there two years ago for 9 months . They have good equipments and coaches .

This workout is very intense, if you are new to CrossFit this not the place you want be. The trainers there are not energetic ,the enrgy is very low there are othere great CrossFit in OC read more

I have been crossfitting for over 4 years out of Burlington,Ontario,Canada and often find myself looking for an affiliate while travelling on business. Many times I leave feeling dissapointed and out of sorts with the group....NOT INSANTIY!! The coaches are awesome, very welcoming and NOT judgemental. The athletes at this facilty are welcoming and kind. The WOD's and the structure of the class time are great. Always begin with some sort of skill/strength training and follow with a excellent WOD. The classes are organized as far as time goes and the coaches do an excellent job in keeping the athletes within time limits. I give this facility, its equipment, its coaches, its WOD's and the people a 5 star. I am so glad I found Crossfit Insanity and I plan on attending classes at this facility everytime I travel on business. GO for it!! read more

Crossfit Insanity! This place is awesome. The athletes are so welcoming and fun to workout with. It very much feels like a community. The coaches are top-notch. Dave is as strong as a Mack truck and Michael always knows how to phrase his coaching to make it sink in. I learned a lot in my short time there. I had to move on for reasons outside of CFI. They were great and always will be great! Check this place out!!! read more

Where do i begin- all I can say to start is you have to believe in yourself and want to make a change in your life for this to work for you. A little back ground to show you how amazing Crossfit is and how i saw results in the first month. I started Crossfit Insanity on April 2nd 2012. I grew up in shape and very active. But over the years I became a workaholic and spent less time working out and playing sports and more time furthering my career path. My first son was born in January and I was tired/exhausted and wore out from work and being a new dad. My buddy was praising crossfit for about a year to me and I kept saying " yeah yeah yeah" I'm to busy and have no time for that. I finally stepped up and realized I was getting heavier and heavier and needed to do something. I went in and watched a workout and was VERY IMPRESSED! The trainers were very nice and worked with each person to make them understand the workouts and techniques. So I stepped up and said " WHAT THE HELL GIVE IT A SHOT". On April 2nd I weighed 254 lbs (I'm 6'5"). I went through the Basic Essentials class for the first two weeks at 3 days a week. After the first two weeks and 6 classes I was sold. SOLD ON EVERYTHING. Most people would just throw in the towel and give up. And believe me I wanted to at first. But I stuck with it. After one month I lost 22 pounds and was down to 230 lbs from 252 lbs. My wife and friends could see a change and I FELT a change. Got stronger and felt healthier. Please note I listened and followed everything the trainers said and taught me. They encouraged me to follow the Paleo Diet ( at first I didn't think I could do it). But I gave it a shot for two weeks and started to read a book recommended by Arron ( one of the trainers ) and I loved it. I could see a difference and I believe that with crossfit and going Paleo this attributed to my success story so far. In summary I just felt better all around. I started to attended the crossfit classes 5 days a week. Another quick side note is I had a 24 HR Fitness pass and never went. I hated the clowns at the gym and hated the crowds. Here at Crossfit everyone that attends is very nice and are helpful. No one is rude or cocky. So in a nutshell all Trainers here at Crossfit Insanity are very nice and fun to be around. They help you better yourself/push you beyond points/levels you thought you could never go. They are very patient and answer all the questions in the world you might have. Fellow Crossfitters are just like family. A lot of fun to be around and also push you. If they finish before you they push you through the workout your trying to finish-great support and extra boost of energy to help you want to push yourself harder and harder each time. The box/gym is very clean and all equipment is new and in good condition. Come in and join us for a workout! read more

When I started CFI, I could not complete a 200 meter run and I could only lift a 15 pound bar with no weights - I was very out of shape. What I love about the people at CFI, is that they always encourage you to keep going and never make you feel embarrassed if you're the weakest link. I gradually am becoming stronger and gaining more endurance which only motivates me to keep going. I'm only 4 years from the big 4-0 and I plan on turning 40 in the best shape of my life! read more

This CF box is amazing. Great people, Hard workouts, and most importantly, the coaches are fantastic. They are so nice, know so much, and helped me improve a great deal. If you are in Costa Mesa/Irvine JOIN Insanity NOW! read more

I can't say enough positive things about CF Insanity. A bit of background: my husband started in January of this past year and finally convinced me to join in April. When I took the essentials course (required for all those new to CF), I could barely lift the training bar over my head. My push-ups were pitiful; so bad in fact that I couldn't even get my chest a half inch off the ground and found it difficult to even worm my way up. I had no idea how to lift as I only occasionally picked up a 10 pound barbell at 24Hour Fitness, and my only athletic experience was a semester of 8th grade basketball and a few summer swim teams. So needless to say, I was a true beginner. But the coaches understand that most of us don't have experiences geared toward CrossFit perfection, and take this as an opportunity to work with you to get better, stronger, and help you to succeed in ways you never thought possible. Flash forward 6 months and I can do several push-ups with perfect form and even a few unassisted pull-ups. Not to mention I've developed a crazy addiction to cleans, jerks, deadlifts and my favorite--squats! Insanity is so good that I actually feel depressed on days I can't make the box for a WOD. You might say it's crazy and "just a workout", but give Insanity a shot and watch your confidence increase along with your strength and stamina. And an added bonus: you'll develop a whole community full of new friends that cheer and support you as you work to get better. How's that for "just a workout?" read more

From the get-go, I've only had super positive feedback about CFI. What makes my experience somewhat unique is that I continued to CrossFit through my pregnancy, which other strong mommas have also successfully accomplished with CFI's expertise. Mara, co-owner and coach, is incredibly knowledgeable on the subject since she crossfitted thru her entire pregnancy years ago. After I got the go ahead from my doc (which, btw was a resounding "yes" re: CrossFit), Mara provided me a list of recommendations - plus movements to skip for safety, and modeled important modifications. It was common for me to arrive early and chat with the coaches about how I could go about scaling the WOD, and what substitutions were needed - all the coaches were really attentive and enthusiastic about making it possible. Furthermore, CFI members routed me on, kept my spirits high and provided a whole lotta luv when I needed it! Working out left me feeling healthy, strong and energized. This box has been a blessing for me, and while my circumstances necessitated a temporary move cross-county when seven months pregnant, I credit CFI and their fine ass community for the fact that I've been able to CrossFit 3plus times/week right into my 38th week. I have two more weeks before baby arrives, and feel it's high time for a break, especially since my little dude is doing his own clean 'n jerks in my tummy. read more
