The 12 Irvine

I love the12! This is a great full body workout with a motivating and team filled atmosphere. Nichole is one of the best trainers I have come across and to top it off she is witty! I love starting off my days with the12 crew!

I can't say enough great things about The 12. The workouts are always new and exciting, so there's no way you'll ever get bored. I'm an avid long runner, so this is the perfect way to cross train and build my strength. In one hour, you'll get the best full-body workout that incorporates weights and cardio. The atmosphere and positive community are what keep me coming back again and again. Do yourself a favor and sign up for one of Nichole Ormsby's classes. Guaranteed you won't regret it!

Great facility and staff. I've never been able to keep to a workout schedule and keep motivation but the trainers and atmosphere here have kept me going for 2 yrs. High Intensity interval training really keeps this fresh and fun. Great workouts. Uniquely focused body part workouts daily. A lot better on the body than CrossFit with similar results.

I love the 12! I’ve been going to the Irvine Mesa location consistently for about 3 weeks and can really feel the difference. This is the most motivated I’ve been to workout in a long time. The trainers are knowledgeable and, even though they can be large group classes, they take the time to get to know you. They also help modify exercises to match your abilities. I can’t wait for class tomorrow!

Alex and Nichole (really all of the 12 trainers) are two of the most amazing, inspiring, motivational people I have ever met. They make me bust my butt every class, hold me accountable, and help me to achieve personal goals. They genuinely take the time to get to know you on a personal level, which in a group setting you would think is almost impossible, but they do it and do it so well!! You can really tell that helping people achieve their goals is why they do what they do.The 12 promotes a community culture and people from all backgrounds, ages, and fitness levels are welcomed and accepted. This type of environment makes it so much easier to adapt when everyone is so welcoming and non-judgmental. The trainers will not tolerate it otherwise, seriously.The facilities are great, always kept very clean. Love the products/supplements that are recommended to help with recovery, fat loss, and muscle building.

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.

The 12 has a great combination of strong leadership that preaches positivity while putting us through strenuous workouts to make me feel better. The team aspect that they provide does a great job of holding us accountable and build a sense of a community at the gym. Nichole is an amazing trainer who Is not only expertly trained, but inspires the class with her own personal journey. The 12 is a great place to workout and a great community to be a part of!

These guys have created an amazing community around fitness, health, and well being. I can not sing their praises enough! They keep you accountable through getting to know you, and are not afraid to call you out to push you to greatness!

Everyone at the 12 brings positive energy in a way in which you find that extra push to keep going! The trainers are all top notch, expecting you to give your best, and motivating you even when you think you can’t go anymore. Definitely recommend!!!

Always a fun time here at the 12 - Irvine Mesa. The trainers a really knowledgeable and can help you reach your fitness goals. Also, shoutout to Amandie at front desk for helping me get set up. #12nation
