Have been going to The 12 for about a month.. Absolutely love the energy of the classes and the momentum they fuel me with. Highly recommend!

I love lifting weights and HIIT training; however, unless I have a class to go to, I will rarely go to the gym. I thought the 12 would be intimidating at first, and I would not be able to keep up with the other members; yet, the members and instructors are very kind here. No one judges you and the workouts are amazing. I have completed 30 classes thus far and I look forward to the workouts so much that I signed up for the unlimited monthly membership. I already feel better and can tell I am getting stronger.

I love the staff, trainers, group classes and environment at The 12! I push myself harder during the group workouts than I would if I worked out on my own, and we do exercises I wouldn't do otherwise. I feel like the trainers actually care about you committing to your practice and about making sure you do the exercises properly. The music is great, and it's fun to train with your friends!

I loved everything and everyone at the 12. I was on vacation and I love working out so I came to this studio. The 12 coaches and front desk made me feel so welcome. The workout was very challenging and Alex was there to hold us accountable to getting our workout done. I would recommend this gym for someone who is looking to have fun while working out and make changes mentally and physically. So much inspiration to do your best at the 12.

After being a member of 24 hour fitness for about 11 years, I felt as though I was no longer as motivated and found that I wasn't pushing myself as hard to work out. A friend of mine introduced me to The 12, and I was immediately hooked. The constantly changing workouts, the awesome instructors, and comeraderie within the community keep me motivated and consistently coming back.

The 12 is above the rest with their pure dedication. Their classes, training and equipment are spectacular.

Indeed, any reputation I have for physical fitness this summer stems, in truth, from the extraordinary guidance Nichole Ormsby, Sarah Gillette, and the rest of The 12 team so selflessly provide. I know I speak for many of my fellow gym-mates as well when I say we are grateful to be a part of this family, and we have a lifetime ahead to prove that. This gym not only enables you to gain healthy habits, but mad respect.

The 12 is an amazing group training gym! I love all the instructors here at Irvine Mesa. Sarah, Nichole and Alex are all super energetic, motivating, friendly, etc. and all the staff here are so friendly, helpful and personable. I signed up for two free classes and after your first class, you get a choice between getting 10 classes for $99 that expires in 3 months or unlimited for a month for $99. I went with 10 classes because I was traveling soon. Once I came back I finished my 10 classes in 3 weeks! I was hooked! So I signed up for their unlimited membership which is $179 per month. I don't like going to the gym so going to the 12 helps me a lot and I've been coming here for two months and I already see results!
I love the 12! :)

Before coming to this gym I was in a three year long depression. from going to jail to bindge drinking. But I made the choice to change. And from the first minute I walked in here my life has been nothing but greatness. If you have the drive to do HIIT workouts The 12 is for you. You will feel welcomed like family. And if your in class with me I will motivate you becuase thats how we do it here at the 12!!!!

Maddie is the shiz. All the trainers here are a lot of fun and keep you driven while making sure to correct your form.

The 12 offers a great training regiment to challenge yourself and reach the goals you're striving for. The 12 team is extremely resourceful and takes pride in their work! Trainers like Madison make sure everyone is giving 100%, and provide a fun and friendly environment to get in the best shape of your life!

Amazing workout! A great group fitness facility. The instructors kick ass!

I have tried plenty of gyms in my life and The 12 has been the best so far! The workouts are intense, yet safe and very effective. I am always looking forward to the classes, especially under the guidance of Nichole! Her enthusiasm and encouragement has always motivated me. Come check it out! You will be hooked!

Excellent workouts configured to target specific muscle groups, utilizing a variety of resistance implements. The trainers are knowledgeable, encouraging, and make putting in the hard work a fun experience!

Love this place. The community is amazing, the workouts are challenging, and I always end up having a lot of fun. Each day works out a different muscle group as not to overly burn out your body. I've been coming here for 2 years almost daily and have noticed everyday tasks are easier due to the fitness The 12 has prepared me for.

The 12 consistently delivers the best workouts I've ever done. I've tried other things and will always come back to the 12 when I can and when it fits into my schedule. I used to go religiously until I started back at school, so it's a bit tougher for me now. I just went to the new Irvine location last weekend and it's fantastic! The 12 also has the best staff, trainers and front desk associates! Love everything about you guys!

Motivating atmosphere that makes working out so enjoyable! All of the trainers are wonderful and each day of the week is filled with different exercises that focus on specific body parts (ex: Tuesday- legs, Friday- cardio). Definitely recommend checking out The 12 if you're looking for a gym in the OC, especially since they offer the first two classes free.
