The 12 Irvine

I've been going to The 12 once a week for a few months and absolutely love it! The workouts are intense but the hour goes by so quickly because it's so much fun. Nichole is awesome and so is Diggy! I love the variety and the positive atmosphere. Even going once a week I've noticed weight loss and, more importantly, I feel stronger. Cannot recommend this place enough!

I have been a member of the 12 for more than two years now, taking Nichole’s 6:15 am class.I love the variety of workouts the classes provide to keep things interesting and challenging.The best part about the 12 is Nichole- you really don’t come across fitness trainers like her, not to mention human beings like her. She’s relatable, real and never runs out of things to say. Nichole is an expert trainer, killer DJ with good variety and a fun person to start your day with. She’s positive, playful and extremely thorough. You can tell she loves her job, the gym and the people she trains. From novice to advanced, every person that walks into her class is treated with the same amount of respect, attention and compassion.I am grateful to have found her and the 12- take her class asap!

I love the 12!! I was looking for a gym that would push me to new limits with my fitness- I found it here at the 12! It is such a great community and the trainers are the best! Shout out to Nichole for the early morning workouts and always having so much energy for her classes. She is always uplifting, knows everyone personally , and makes working out early fun but also challenging!

Update on The 12 I now love it even more! I have seen tremendous results and its my first time having access to their nutritionist Nikki Boyd. And with her guidence and the continued support of everyone at the 12 I can say im definitely on the road to becoming my best self.

The workouts are awesome, science backed, and combine cardio and strength. The trainers are seriously next level good. Motivational, helpful, friendly, and push you to do more.

I’ve been attending The 12 for a little over 2 months now and I absolutely love it! It is a super motivating environment with people of every skill level in each class.Nichole’s classes are the best!

Totally worth waking up and coming in at 5am! This gym has the best coaches, management, and community. Not to mention they follow the COVID-19 protocol, making the environment a safe place to get in a good workout.

This is a very personal review of The 12 - Irvine Mesa location....It has been 5 years this month (since March 2016) to when I decided to change the direction of my health. I was 198 lbs and teetering towards the two century mark. For my height and age, it was nothing but all bad!In the timeframe that I have been going to The 12, I've made personal gains that I'm incredibly proud of....With the guidance of all my trainers: Nichole, Uli, Eunice, Brooke, Dana, & Jared, I have maintained a healthier weight and learned to eat better.I have also made some great friendships. I'm normally someone who's fairly introverted, but it's impossible to not engage with the positivity this gym creates. Egos are checked at the door and you never feel like you're being judged.I got introduced to this gym and the direction of my life has changed.Training is part a healthier you and "The 12" fit that part of my life very well, THANK YOU!!

I recently moved to Costa Mesa and a girlfriend of mine suggested I try this gym! I was a little nervous since I haven’t worked out consistently since before Covid and I feel really out of shape. I went with my friend and as soon as I walked in I was greeted by very welcoming faces and was put at ease. They have a temperature check and require everyone to bring towels to clean the equipment between stations which I appreciated. Once I walked into the main room I started to panic a little because there were a lot of equipment and exercises I wasn’t familiar with. Luckily they go through each station and demonstrate the exercise before we begin. I like that they also have you do mini exercises between stations to keep your heart rate up. I’ve only had Eunice as an instructor and she has been great! I was so pumped after the workout and so excited to get back In shape that I signed up as a member :)

I’ve been going to The 12 for about 2 years and I absolutely love it. The two trainers I have the most time with are Nichole and Uli they are both fantastic, definitely a major reason I drive to this location even though I live a block from the other location. Uli is a great coach, plays the best mix of music and it’s just loud enough to be motivational. I get to work out with Nichole now more, it’s great that the trainers enjoy working out at their job. You’d never want to eat somewhere the cooks don’t eat right!?
