THE HARDEST LIFT IS TAKING ACTION. LET’S GET STARTED TODAY!

Got Questions? We've Got Answers Right Here!

Easy! Click the “Get Started” tab to book your free consult and gym tour. You’ll meet with a coach to discuss your goals, current fitness level, and what you’re looking to improve. If it feels like the right fit, we can get you started the same day.

You’ll notice changes fast. Most members feel stronger and more energized within 7–10 days and start seeing visible results in about 30 days.

The key is consistency — show up for your workouts, follow the nutrition plan, and stick with it. Start with three sessions a week and you’ll build habits that last.

Yes! Our coaches provide effective, easy-to-follow guidance on nutrition, sleep, and recovery — giving you the tools to eat better, recover faster, and get the most out of every workout.

Not at all! Most members start exactly where you are. We assess your fitness level, goals, and experience, then tailor the program to fit you. Every workout is scalable, with options for all levels — so you can progress at your own pace and keep improving week after week.

Simple — we actually give a $#!+.

We’re a locally owned gym built to make a real impact on the health and happiness of Fairfield, the Caldwells, and our surrounding communities. You’re not just a number here — everyone knows your name. We’re a tight, no-judgment community that pushes, supports, and celebrates you every step of the way.

If you’re just starting out, 2–4 sessions per week is plenty to see results and let your body adjust. Expect some soreness early on — recovery is part of the process. As your fitness improves, aim for up to 5 sessions weekly to maximize progress.

Each session is built to cover the essentials — strength, endurance, mobility, muscle development, and fat loss — in a fun, challenging, and supportive environment. Some workouts focus more on specific goals, but every session stays balanced and effective. Workouts are posted in advance so you always know what’s coming.

Our coaches are here to keep you accountable, guide your nutrition, and help with form or modifications whenever needed. Whether it’s motivation, consistency, or clarity — we’re here to help you keep moving forward.

Each 60-minute class is led by a qualified coach and starts with a personalized warm-up to prepare your body and prevent injury. After a quick workout brief, your coach will guide you through each exercise — offering form corrections and modifications as needed. Every session ends with a cool-down and mobility work to improve recovery and keep you moving strong.
