I always gave a great work out here, the staffs very knowledgeable and helps you set and achieve your goals. Feels great when you're about quit and you hear all the trainers cheering you on to finish your workout. read more

I was a dancer for 10 years and then a competitive cheerleader for 4 years. For the past 8 years, I have been looking for a gym or fitness program that I could enjoy doing regularly as well as kept me fit and healthy. I have tried EVERYTHING under the sun including barre classes, boot camps, Spin, TRX, boxing, yoga, Pilates, cardio classes...the list goes on. A year and half ago, I found Crossfit Synapse. Crossfit can be an intimidating world to step into. As a petite female, I was definitely nervous. I can honestly say that I was nervous for no reason. From my first day, this gym has given me life. The people here are welcoming and everyone cheers each other on. It's more than just a gym. It's an hour of your day where you focus on you. The workouts are hard but incredibly rewarding. Jimmy and Allison are so knowledgeable. Everything is scale-able so that no matter your skill level, you will be able to actively participate and get a kick-butt workout. Don't think about it...just come. Whether you are interested in losing weight or just want to be a healthier, better you, do it at Synapse. It's truly a gem in Tarzana. read more

I don't want a gym , I want a community, I'd rather be challenged than be comfortable , I'll take grungy over glitz , I want to work like an athlete rather than treated like I'm in Hollywood. My sweat are my tears and damn do I like to cry a lot. I like being pushed not catered to and most important I want to finish on the floor not on my feet because finishing on my feet meant I didn't work hard enough. This gym gives me everything I could ask for. Being pushed to my limits and accomplishing more then I could have ever imagined. read more

Dropped in from Phoenix! Great WOD to start the day so we can enjoy the rest of our vacation without feeling guilty!

I came to Synapse friendless and completely fresh-faced to the area. An old friend had recommended that I try CrossFit. She had given me a list of different gyms/boxes to check out and Synapse was the first one. Little did I know that I had stumbled upon a HUGE treasure. Allison was the first person I met and her positive energy and smile made me feel welcome right off the bat. And a few days later when I met Jimmy, the other owner, I had a feeling that I had found a very special place. I didn't even bother going to the other gyms that was on my list. You hear a lot about Community within CrossFit, but I really can't think of any other place that exemplifies that phrase more than Synapse. Throughout my time here, I've made friends and learned a lot about myself, others, and exercise. They take form seriously here. The level of perfectionism and attention to drills, technique, and mobility is something that I haven't seen at other gyms, and if you care about your body in the long run, it's a HUGE bonus. You'll get fit, alright. And you'll get fit PROPERLY. The other amazing part of Synapse is that they also don't take themselves too seriously. Aside from jokes and puns, the warm ups themselves make it worth going there before the crack of dawn. There also are many opportunities for you to meet other members of Synapse; through Flag Football, meets, and even community WODs to support fellow competitors -- you can't help but feel part of a family! And the best part is that dressing up is almost always mandatory. :) Synapse is more than a premiere gym in Los Angeles. It's Home. ** I should also mention that I am now living in Oregon and I STILL miss these guys every day. read more

I love CrossFit synapse! The coaches here are always friendly and encouraging. The members are very inviting and welcoming and it's because of this thatI look forward to going in to the gym everyday. Before joining CrossFit synapse I had no idea how much I was actually psychically capable of. Since joining synapse, my confidence, endurance, and strength have all grown and I owe it all to the people here I get to call my friends. All in all- 10/10 would recommend read more

I absolutely love this place. I started going here about a year and a half ago and it's more than just a gym. Everyone there is so supportive of everyone else and the instructor's are amazing. About a year ago, I told Jimmy that my daughter (13 at the time) needed something to get into and she wasn't crazy about sports. He's been working with her on weightlifting ever since and she is so happy there. Next weekend she has her first meet! I love this place, I love the people, and I can't believe I hadn't written a review yet :) read more

I have to agree with others that complained about Jimmy's attitude. I had never done crossfit before and all and all he was super unhelpful, unfriendly and unwelcoming. I went for a few weeks but actually felt uncomfortable coming here! This is crazy seeing the amount of money you pay to be a part of this gym. What you're really paying for is the instructors, when they're awful, what's the point? read more

I have been to several CrossFit affiliates. CrossFit Synapse is the best. If you are new to CrossFit, this is an amazing place to start. They are really concerned with form and preventing injury. They are a great balance of encouraging and challenging. If you have been to other affiliates, Synapse will make your PR numbers grow. Allison and Jimmy are excellent owners/coaches and all their coaches are great. Synapse is a fun and welcoming community. I can't recommend them enough. read more

I can't say I'm a diehard crossfitter like some, but having started about a month ago I can honestly say I have never seen results in such a short amount of time. I go one to two times a week in addition to Goddess Fitness and S Factor and the combination of these have increased my strength, flexibility and endurance. Crossfit has done wonders for Goddess/S and vice versa. I can't express the amazing benefits I've gained from doing both. There's just not enough time in the day to exercise as much as I would like to now that I've added Synapse to my routine. My mom who is 56 years old and recently recovered from a very major surgery has started going to Synapse as well and is completely addicted! This is for ANYONE of any age/size/ability. The trainers are fantastic and break down every movement for those of us who have no previous gym/circuit work out experience. They will also change the workout of the day for your personal needs/injuries/ability. I could go on and on, but just come in and try it out, you won't be disappointed. read more

I followed Jimmy and Dan from another Crossfit gym that I was a member at. I wasn't unhappy at the other gym, but the main reason I did it was because of Dan's coaching. I've had alot of success with Crossfit (lost over 40 lbs and gained tons of cardio, endurance, and muscle), but I've made even greater strides in the short time that I've been at Synpase. Dan's an incredible coach, now only in showing you the proper movements but also a great motivator, who pushes you to test your limits. Jimmy is awesome as well and really good with newbies. This is Crossfit the way it's meant to be done, no frills, just tough solid workouts. The people are great, there's plenty of parking. On hot days it can get a little stuffy but no big deal. If you haven't tried Crossfit and have been scared to, this is the place. They have special classes for newcomes so you won't get overwhelmed. Jimmy and Dan are super supportive and you'll be on your way in no time. read more

After working out at other Crossfit gyms in the valley this one is by far the best and has quickly become a new home base. The coaches are there for you 200% making your workout experience and results the best possible. Their expertise has taken people from all different physical backgrounds to tremendous athletes. I've personally lost 35 lbs and look and feel better than I ever have in my life. I went from never working out to not being able to imagine going without Crossfit and specifically working with Dan and Jimmy at Synapse. The results speak for themselves. read more

I dropped in here for a couple of classes in December. In short, this place is awesome! I'm still a relative newbie and Allison was super helpful in actually walking through any new technique and really providing helpful pointers (i.e. pointer our the toes a bit, shrug the shoulders a bit more, widen the grip, etc.) in a really nice way. The community is also exceptional, I was new and almost everyone in the class came up to meet and greet - that just doesn't happen in other crossfit gyms I've been too. I will definitely come back any time I'm in the area. read more

Awesome atmosphere , great coaches , and the best workouts in the valley!

It took me awhile to find a place comparable to the high quality of coaching & programming I was used to back in Colorado - but I finally think I've found it at Synapse. I came in with some minor injuries and they have been great about modifying movements and suggestions for rehab. The coaching is great with a lot of focus on technique. Plus the members of this gym are awesome, little to no ego and very friendly. Very happy to finally have found my new CF home! read more

CrossFit Synapse is transformational. The trainers are experts and will guide you through the workouts to keep you safe while you build strength and stamina (you'll be surprised how quick this happens). The classes feature individual one-on-one training and the motivational benefits of a group workout, which is unlike any experience I have had before. On top of this, all of the other gym members I have met are genuinely great people that offer support, training tips and the occasional welcome dose of humor. There is a great thing going on here and if you are looking to change yourself you won't be disappointed giving CrossFit Synapse a try. read more

I came here with a Groupon the 1st few days I loved I was either training with Matt or Allison which they are both really nice and take the time to actually show you how to do it correctly. I've never done Crossfit before so I thought I would give it a try which I loved at the beginning. Now that I came across JIMMY I don't even want to go back and finish my Groupon this guy is a total As*hole. The 1st time I saw him he said are you here to try out?? I said no!!! he said oh you are here with the "coupon thing" and I said yes I am here with that "GROUPON THING" and he just said ok didn't introduce himself or anything. Not only that he doesn't bother to show anyone ANYTHING he doesn't even demonstrate you ask him how do you do it? his answer is "you should know" if you show him something thinking that's what he is asking you to do he tells you "I've never seen that before" HELLO!!! how am I supposed to know the name of all the different stuff they do in crossfit if I've only been there a few times. He loves to chit chat with all the other students that have been there for a long time he is always correcting their posture but new students he doesn't even bother he makes you feel like crap I left there not wanting to come back I will never pay $169+ to deal with someone like that. Sucks because I referred 2 of my other friends here and they also have nothing positive to say about JIMMY he thinks he is all that and a bag of chips when he isn't he used to be fit but now he is just fat. I feel bad for the new students that have to deal with him total a*s. DO NOT BUY A GROUPON FOR THEM AND IF YOU DO TELL JIMMY OFF THATS WHAT I SHOULD HAVE DONE BUT SINCE I AM NOT LIKE THAT I DIDNT SAY ANYTHING BUT NOW AS I WRITE THIS I WISH I WOULD HAVE SAID SOMETHING TO HIM. I WILL BE CALLING GROUPON TO SEE IF I CAN GET A REFUND SINCE I AM NOT SATISFIED. read more

I drop into this box when I'm in the area for work. I travel quite frequently and see a lot of boxes, and this is by far one of the most impressive. Allison and Jimmy (coaches/owners) are super friendly and super knowledgeable. Their attention to detail really ensures that people know what they are doing, spending lots of time on warming up and emphasizing proper form. The equipment is solid - plenty of bars, weights, racks, sleds, weightlifting platforms - and even rumble rollers! Awesome. Very welcoming community, too - even with only being a drop in, people stop and introduce themselves. Again, I rarely experience that at most other places I drop into so it just shows you how awesome the community is. It's too bad I only get to hang there once a quarter. If I did live in the area, I could definitely see this place being my go-to jam. Solid box, with top notch coaching and a great community! read more
