Newport Mesa: 140 E. 17th St. Our signature Group Training group classes are designed to provide each member with a dynamic, energy infused, results driven experience in 60 minutes. Our Signature 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 EPOC 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.

We are your biggest fans.

For our coaches, the most rewarding part of the process isn't just writing the programming, it's watching you break through plateaus and hit milestones you once thought were out of reach. Your wins are our wins. Let's keep setting the standard. 🖤

FORM FRIDAY with Coach Em 💪

Building stronger legs requires strong form! Em is breaking down the Reverse Lunge: keep your chest proud, drive through your front heel, and lower your back knee with control. It's all about stability and controlling the weight.

Save this for your next lower body day and let's get to work!
