Boredom busting, plateau-proof workouts that are scientifically formulated to achieve results!

Our signature Training group classes are designed to provide each member with a dynamic, energy infused, results driven experience in 60 minutes. The 12 Training combines body part specific, multi-directional movements utilizing free weights, resistance bands, cardio equipment and body weight with high intensity intervals. These circuit style classes are deliberately formatted to burn maximum calorie levels within each group class. Igniting The 12 Training effect, the body continues to burn excess calories 18-24 hours post workout, effectively sculpting, shaping, and shredding each person’s physique. With no two workouts ever the same, The 12 has developed a dedicated following for these boredom busting, plateau-proof workouts that are scientifically formulated to achieve results. Explore our Classes Here.

Don’t get caught in the details

Wait… I’m on the waitlist?!?

  • We don’t want that to happen to you either!

  • Our Reservation Policy was designed to make sure we are maintaining the best training experience for all of our members.

  • To be guaranteed a spot in the class of your choice, we require that each member pre-register for their classes.

  • Keep in mind classes can be reserved up to one month in advance. Members are always welcome to drop in for a class, but keep in mind, if the class is sold out, drop-ins cannot be honored.

  • Don’t worry- every class has an online registration capacity of 30 and a wait list of 10. So, if you are on the wait list you will be notified via email if someone has cancelled and you have been added!

Pre-Registration 101
Please download our app “The 12” on iTunes or DROID to Pre-Register for your classes. You can

  • Register for your classes up to a month in advance.

  • Click here to locate our app download page.

  • Members who arrive for classes they have not pre-registered for are subject to the availability of the classes and are not guaranteed a spot if the class is already at capacity with pre-registered members. So, secure your favorites in advance!

Oops...Can't Make It?!?!

  • Working late? Baby sitter cancel? Just not feeling it? If you need to cancel please do so at least 8 hours prior to your scheduled class. This will allow those on the waitlist to be notified that they have been added to the class…and usually there is a waitlist full of members who are vying for your spot!

  • If you fail to meet this guideline you will lose your session or be charged $15 if you are on the Monthly Unlimited package.
