Testimonial: Zee K.

Being a single mom, having social anxiety, and not knowing what to do was my excuse for why I couldn’t go to the gym. I would walk into a gym be overwhelmed/intimidated and leave. But Polarize was different. I came in with no experience but the coaches and other athletes never made me feel less than. All the movements always had options that I could scale too and it made me feel accepted. My kiddos are no longer an “excuse” because they get to come. While I work on being a better and healthier me they get to play and enjoy being a kid.
If you would’ve told me last year that I could be physically active let alone at a CrossFit gym I would’ve laughed. But here I am a year later. Polarize CrossFit has not only helped me get back to who I was before becoming a mother but it has become apart of our village; a second family.

I have been attending this establishment for about a year now and I am very satisfied! Jo is great with a lot of helpful and nice people working out here. The price is very reasonable and they are willing to help you with anything. The equipment is great and again they help you learn how to operate it. Very pleased and hope to have many more years with them!

I highly recommend Polarize CrossFit to anyone looking for a new box or one to drop in on.  All of the coaches have been exceptional. Coach Jo is a true gem in this world. You can tell she loves what she does and she welcomes anyone that walks in the door with a smile and desire to help. They always included my husband and children in events and encouraged them to be a part of the community, member or not. Knowledgeable, friendly and committed to seeing people thrive in whatever their personal abilities may be. I never felt judged or intimidated by staff or other members! Polarize CrossFit makes you feel like family. I made friends, saw myself grow in strength and ability and most importantly I felt like I belonged from day one. Drop in, you will not regret it!!

Al T.

Really enjoy the members of this gym. If you want to experience the “community” that CrossFit talks about, this is the place.

Liza M.

I joined in May 2022. I must confess that at the beginning I was scared, I felt intimidated by the idea of ​​going to a gym with CrossFit athletes, especially after more than ten years of a sedentary lifestyle. I highly recommend Polarize CrossFit to anyone looking for a place to change their life. All of the coaches have been exceptional. Especially, Coach Jo, you can tell she loves what she does, she welcomes anyone and adapts to any level of each athlete. She also helps me and keeps helping me with exercises, advice, and my knee pain which has almost gone away since I came here. I remember I couldn’t even bend my knee or use steps, now I am jumping boxes. Polarize CrossFit makes me feel like family. You can make friends and feel welcome while growing your strengths and abilities, and most importantly I felt like I belonged here from day one.

Sue V.

This place is the best for every fitness level and age! Great for young and old people like me!

Meet Yuri…
Never in a million years did I think I can lose my my pregnancies’ weight. For awhile I kind of accepted it and I didn’t have the energy to do be active with my kids or for myself. I was on a boring routine that made me feel miserable.
After trying 24 Hour Fitness for a year and the YMCA for 6 months with no results, I knew I needed more if I was really going to do this!!
One day I was driving on Industry Street and I saw the CrossFit gym sign and I stopped and went in. The coaches made me feel so welcome and everyone was so nice that I signed up right on the spot!
I immediately fell in love with CrossFit and I managed to lose my weight, gained confidence, strength, energy, you name it and Polarize CrossFit gave me back what I once was (before kids lol).
Now there’s nothing I won’t do with my 5 kids plus more. Not only did I become stronger, I also got a second family, a second home. I naturally take care of the gym like if it was mine haha. My kids have grown up here, they feel comfortable and safe and that alone I would not change it for the world.

Hiren M.

I have been attending Polarize CrossFit for about 3 years now. I initially joined the gym to attend their barbell club. My goal back then was just to increase my overall strength. I was pleasantly surprised that the members of the barbell club had a wide range in terms of age and level and I found that I easily fit in. The coaches and fellow members helped me along the way.  I achieved my goals while learning proper form and technique.  My wife loved the CrossFit and Sweat Classes.  We started taking the CrossFit classes together.  My health and fitness was boosted even more.  The coaches are great at modifying the workouts to my level but I still can see great results. The barbell club complements the crossfit workouts very well. I strongly recommend Polarize CrossFit to anyone who wants to improve their overall fitness, irrespective of their goals.

Sandra S.

Fantastic coaching. Excellent workout.

Great camaraderie. Encouraging to be the best you can be. Strengthening your whole body to be physically fit. Never felt better.

Jamie H.

The BEST! Great coaches and community! Plus side, the gym has a ton of space, natural light and is very CLEAN!

Anthony I.

Great community and great coaches! This place brings people together and is great for all levels of fitness. Coaches will help you if you are just starting your fitness journey as well as help the more advanced athletes work on their advanced skill movements.

Jeff and Brittany S.

My husband and I dropped in from out of town and I can’t say enough of how welcoming and nice everyone was to us! Coach Jo and Mike were both very helpful with technique and gave us great pointers. The facility was also very clean and organized. I’m so glad I found this CrossFit and I will for sure come back the next time we are in the area.

Taylor S.

This is by far the best CrossFit gym I have ever been to. I spent just under two years of my life with this gym (only left because my boyfriend and I moved to Utah). A close knit gym is what I believe is the most important quality for a good CrossFit gym to have. It helps push athletes and coaches to stay motivated while  continuing to improve. The coaches and athletes treat each other like family here. They push and encourage while knowing each athlete’s goals and limits. They celebrate small victories as well as large and improvement is what motivates coaches to continue to push and support their athletes. I have tried many new CrossFit gyms out in Utah and I can’t find one that compares to Polarize CrossFit. I miss it so much and I wish I still lived close by.

Agnes C.

Jo and the team here at Polarize CrossFit are amazing!! They are genuinely here to see you succeed and what a great environment to be around!  It’s a hidden gem tucked away in Oceanside. Give them a call today; you won’t regret it.

Carrie J.

I love this place! The coaches are excellent and I can push myself as hard or as easy as I want to- no pressure. The gym is always clean and organized. There are opportunities to socialize, attend workshops to learn more- it’s a lot of fun.

Garlan B.

My daughter plays travel softball and needed a local, quality trainer. Finding Coach Jo @ Polarize fitness has been the best! She talks to you, understands what you want and need. The gym is always super clean, always friendly and dedicated staff as well! It’s a must have in your routine!

Susan M.

I had a hip issue that I was seeing a physical therapist for. Most of the stretches and exercises I did at physical therapy were things that we were doing in the Sweat BootCamp at Polarize with Jo. My physical therapist  released me and said just keep going to your boot camp! Thanks Jo!

Gina M.

I’m in Week 3 of the 6-week New You Challenge and am loving it. I feel stronger already and very comfortable there. Yes, I get nervous before the workouts, but once I’m there, I’m relaxed because the coaches are very warm, friendly, enthusiastic, and they take their time explaining what we’re doing and WHY we’re doing it. I’m very impressed with the interest that the coaches have in their clients. I have a new respect and liking for CrossFit!!

Linzie W.

Great group of people and coaches. Friendly, welcoming, knowledgeable, good value. I’ve been doing the drop in rate for 2 months, the fundamentals class has been great to start getting back in shape.

Nolan H.

Great gym, great coaches, great people. It’s always clean. The coaches will help you reach your fitness goals safely and intelligently

Grace B.

BEST GYM EVER!!! I love to work out here every week! You should really try it! SO MUCH FUN! They have the coolest girl in the 4-5 teen class! Go check it out! And the coaches are awesome!!!

Jorge M.

I’ve been a member of Polarize CrossFit (PCF) for about a year now and I truly enjoy working out there. The staff/coaches are friendly, knowledgeable, push each athlete to do their best, and ensure movements are done in a safe manner. The programming is great. It is challenging yet fun. PCF’s hours allow members to workout in the mornings or evenings. The facility is always clean and ample enough to accommodate a full class.

If you’re an experienced CrossFitter you need to check this place out and if you’re looking to give CrossFit a try this is most definitely the place you want to start at.


Testimonial: Amy

Polarize CrossFit and Coach Jo changed my life.

In 2014 I walked into Polarize for my son, and was intrigued by the idea that I might be able to get fit myself.  During my second fundamentals class I had to put my head between my knees… I’d injured one of my feet very badly in 2008 and all the other exercise programs in the world say, “Start by walking”.  Well, I couldn’t walk very far because my foot would swell up.  I was weak, my cardio health was in shambles, and I’d despaired of having any activity in my life again.   Coach Jo helped me, encouraged me, and kept me moving.   Sometimes she stopped me when I needed to be stopped!

Every coach worked with me to get me properly scaled and challenged.   And here, at last, I found that I do have an athletic talent!  I’m strong!  That’s crazy… how did I not know this all these years?   I started with CrossFit, moved to Olympic lifting, and then on to powerlifting.   In 2019, I spent a year working closely with Jo.  She programmed workouts and worked with my nutrition.   Results?  In a year I lost 20 lb, moved my deadlift from 305 to 325, my backsquat from 265 to 300, and dropped my A1C enough to keep my doctor from dosing me with melatonin.   All this, the year I turned 47.

To put this in perspective, by the time I’d worked with Jo for five years, I went from not being able to do half a dozen walking lunges to having an elite level backsquat.  Oh, and when we took the kids to Disneyland, my husband and I walked them into the ground.  Seems all that leg muscle really helps offset the damage done back in 2008.  No more walking stick for me… Polarize changed my life.

Decide. Commit. Succeed.

Karen B.

I will never be able to put into words how I truly feel about Polarize CrossFit.  I was so terrified to arrive at my first workout.  I was feeling so self conscious, and out of shape, and so unhappy with my own body.  I never in my life enjoyed working out, and could always come up with an excuse.  The coaches have brought out the best in me, and have been so encouraging from the very beginning.  Polarize has changed my life forever.  I now look forward to the five days that I get to spend in the gym.  I look forward to seeing each one of the coaches.  I am down 55lbs and going strong, accomplishing things that I never thought possible, and loving how great being strong feels.  I would recommend Polarize to anyone and everyone, and would encourage you to come and be a part of the PCF Family.  Thanks PCF xoxo

Monica C.

Love the coaches, variety of class times and programming. I’ve been a member for almost 2 years and it’s like a second home.

Crystal S.

I have been a PCF member for about a month now and I absolutely love it! Susan and all of the coaches welcomed me and my toddler with open arms; it feels like home now. Family environment!

I was intimidated at first, but I love that each class begins with a friendly game-inspired warm up. It is also important to me that the coaches go through the movements with a pvc pipe to make sure each athlete has the movements down before doing that actual WOD.

I’m also super stoked to join the intramural open competition— held in house. The team spirit and camaraderie is so exciting and makes the workouts feel like fun vs. work!

Caio S.

The best!

A great place for exercise and socializing with neighbors.

Leela K.

Polarize CrossFit is a beginner friendly place. At age 66 with a knee injury, they taught me how to squat properly, and adjusted all workouts to what I can do. Somehow with the new way of exercise, my knee is feeling good and I am back to running. People that can lift heavy weights are friendly, not intimidating as I thought I might be, because we are doing the same workout though at different levels.

Polarize CrossFit is a fun place, we have potlucks, contests, fundraisers and projects. Most contests are team oriented, find or pick a partner and each can adjust your level of competition, that means even a beginner can win the contest. We have a resident dog, so get your puppy fix while you are at it.

I participate in the MAC program which is strength building along with stretch, cardio and balance. I appreciate the routines Lauri sets up for my class and for the gals that attend each session. Jo offers open gym hours conducive with my schedule. Polarize is the place to go for your workouts.

Testimonial: Kai

Meet Kai…
For as long as I can remember, I have been extremely skinny. People weren’t afraid to tell me either, I would always get comments and jokes about my appearance from just about everyone, including strangers, family, and even most friends.
In turn, I’ve always hated my appearance and last year, I decided to make a change. I joined Polarize Crossfit around March of 2021 and ever since I’ve been working with these coaches, I’ve noticed a huge change in both my physical and mental status.
I began this journey at 115lbs with a BMI of a whopping 16.5 (keep in mind an anorexic BMI is 17.5), and now clock in at 140lbs with a BMI of 20.1, a simply unreal improvement.
I feel way more confident and don’t feel the need to cover my body any longer.

Coach Jo and the team are great!  Have been going for over 4 yrs and love the gym’s energy!

Testimonials: Written


They opened their doors to support the NoCo Sober group (via the Phoenix App), which is just way awesome!  Great workout, great facility, thanks for the coaching!

Eric J.

After trying multiple gyms in the area, I picked this one due to its hospitable staff, good hours, cleanliness, equipment upkeep and availability.

I think the gym is a bit of a hidden gem, and its location keeps it hidden from public view. I believe that fact alone makes it so classes are never overburdened with people. This makes it easier to get personal instruction, keep equipment clean and nice, and get to know the coaches and other athletes on a higher level.

For the year and a half or so I have been a member I have attended usually four or five times a week. I usually go in the mornings. Currently due to low numbers in the morning they are considering doing away with it. If they do I will have to go to another gym and that would be upsetting because I feel other gyms are not as personable in the area. Sunday cardio sessions have been done away with for now, but with some more interest it could come back.

Coach Jo is now the owner, and my wife and I have come to know her personally. She has actually helped us with cooked meals when my wife had surgery.


Polarize CrossFit is an amazing gym. Probably the best I have ever been a member of and I’ve been a member of many (as I’m in my 50’s). The people here have become like family to me. Everyone made me feel welcome from the first day I walked in.  All the nervous jitters of joining a new gym was gone in about 15 minutes on that first day and I have always felt welcome since.

Jo is amazing, as a coach and as a person. She has just the right balance of encouragement and positive reinforcement. She will help you push yourself to your limits but never push you to a place where you shouldn’t go. Her knowledge, skills and techniques are superior. Sometimes I want to say…yeah I’ve got it Jo (lol)… but in the end she has made me much better in my technique, skills and my strength has increased dramatically. My favorite words I always hear from Jo are “Look’en good Team!”

The same goes for Rick and Kevin. They are both amazing trainers as well as great human beings. Many times when Rick is working out with the group, he will intentionally hold himself back. I believe this is his way of not wanting to appear to elevate himself over others. It’s ok Rick… you can go for it; our feelings won’t be hurt. My main purpose for writing this review is simply to encourage others to join our gym to strengthen it with numbers and increase our gym family. My review is totally unsolicited and written completely out of affection for the awesome people running our box and for those that I suffer and thrive with day in and day out. The pandemic has certainly been difficult but our gym will survive and thrive again soon as it is one of the greatest places on earth to spend a few hours a week surrounded by awesome people while we all improve ourselves.  Welcome to our family. We look forward to meeting you soon.

Coach Jo and Jesse have been super amazing, supportive, and knowledgeable. I attend the Sweat BootCamp and I feel great afterwards. They consider any injuries you may have had to help modify any exercises. I feel welcomed and cared for at this gym ❤️

Francisco G.

If I could give a rating above 5 stars, I would. I was a member of Polarize CrossFit for about 8 months. Everyone is very welcoming and supportive. Coaches are knowledgeable and patient. Something I really liked is that coaches take their time to show the right posture and teach you how to scale down if necessary to avoid any injuries.

Roz A.

I am part of a great group of women who use the Mature Athletes Circuit part of the gym. I super appreciate having this option. Owner, Jo, welcomes everyone with enthusiasm and genuineness.  I begin each morning there and love it!

Meet Anthony…

I have been working out for the past 10 years and tried ev erything from powerlifting to strictly running. I had even tried CrossFit before and actually fell in love with it after the first day. But I had never stuck to it.
Then I found Polarize CrossFit…Coach Jo has been amazing, professional, and very knowledgeable. I started going to Polarize in July 2021 and have had the best results from any type of exercise I had ever done before and am addicted to this place.
Not only is the training legit, but the community is also amazing. Everyone is very friendly and it is one big happy family. Polarize CrossFit does a fantastic job at making everyone feel welcome.
We go out and have dinners together, have friendly competition WODs, potlucks and Coach Jo has even gone as far to hosting comedy shows in her gym. This place is awesome. 10/10 would recommend!
This is the type of place that you will look back on and smile at your past memories. The coaching and community is impeccable. Coach Jo is the best mentor I’ve ever had and I will always remember this place when I have to leave it.

Amber not only made the Varsity Soccer team she also got an award for the MOST IMPROVED player all thanks to her hard work in the gym!

Testimonial: Dana

Dana’s story:

I had never struggled to maintain a healthy weight and fitness level until I was in my early 40’s – that’s when the extreme swings in weight began.

I had been a competitive athlete all my life & competed at the collegiate level.

I had always been able to lose the pregnancy weight quickly after each of my 4 pregnancies – even though my last 2 boys were only 10 months apart.

I was an avid runner and began lifting weights in the gym at 16 years old. Being married to a Marine inspired and motivated me to stay fit, which is how we met in the first place, on our youth swim team when I was 12 and my husband was 13 years old!

Fast forward to my early – 50’s, when I truly felt “out-of-control” by my lack of fitness and weight gain, not to mention trying to balance hormones, working/coaching competitive high school athletics for 50/week.

Physically, I felt terrible. I had no confidence, no energy, no fitness “purpose”, which had always come so easy and naturally to me.

I lost 40 pounds by eliminating refined sugar & processed foods over the course of 8 months, but had reached a plateau and was getting pretty frustrated!

I had always wanted to try CrossFit but I thought that was only for young & elite athletes – I had never trained in this modality before and wasn’t sure that I could learn a new sport at 53 years old!

On Oct. 20, 2021 I walked into Polarize Crossfit and was immediately hooked! I have regularly been attending 5 days/week, made drastic changes to my work schedule, reset my priorities/purpose, & could not be happier – hubs is VERY happy too!

To say that Polarize CrossFit is one of the BEST communities that I have ever been part of is an understatement!

Best coaching that I have ever received – Coach Jo & Coach Anthony could not be more professional and patient with me; the other members are amazing people! I LOVE IT HERE! I am happy, strong, confident and enjoy learning what I can better with each WOD.

Now when I take my grandchildren on outings, people think I am mom!
