💪We specialize in training correct movement.
This is real training—it’s like having your personal trainer by your side, teaching you every movement with precision. Your guide to hold you back when needed, then push you forward exactly when you're ready.
Our expert certified trainers focus on movement quality—demonstrating each exercise with precision.
🥗Free - 360 Training Nutrition + Fitness + Lifestyle Program
Scientifically proven, it takes 100% commitment in all areas to achieve optimal physical fitness. That is why we focus on a 360 Training Program, encompassing both training inside Forge and lifestyle habits outside the gym.
Correct lifestyle, nutrition and protein play the largest part. While cardiovascular exercise is important for internal health, strength training is necessary to alter body composition. But cardio and strength are not sustainable weight loss tools on there own and should never be promoted as such.

🗓️Streamline Your Fitness Journey with Forge Fitness RSM Gym App.
Effortless - Community
Communication & Scheduling: With our app, you can book classes, view movement videos for coming classes, post and chat with the Forge family - all within the Forge App with just a few taps on your smartphone. Your personal program lives in the app—track your progress, see your data, and view real results.
External and Internal Body Scans
No guessing games or the inaccuracy scales. InBody Test and A1 FIT3D Body Analysis. One focuses on internal body changes — things like fat mass, lean mass, and health markers — typically used at the start and then periodically to track deeper physiological progress over time. The other focuses on external body composition — muscle development, shape, posture, and symmetry — allowing us to track visible changes regularly and compare progress over any time period.
The Gold-Standard Test
VO₂ Max Testing
The gold-standard assessment of your cardiorespiratory fitness and long-term health. Regardless of your performance or longevity goals, VO2 Max is one of the most important metrics you can know.
Forge Fitness offers Orange County’s only mobile VO₂ Max testing, allowing real-world testing at your convenience—not just in a lab. This means more accurate, applicable results.
—targeting exactly what limits your performance in your given discipline.
