Frequently Asked Questions
Why should I choose Crossfire Strength & Conditioning over a regular gym?
I haven’t worked out in a long time. Do I need to be in shape before I join?
Absolutely not. You don't get in shape to join Crossfire; you join Crossfire to get in shape. Our Mayhem Affiliate programming is designed to be "infinitely scalable," meaning our coaches adapt every movement, weight, and intensity level to match your current ability. Whether you’re a former athlete or a total beginner, we meet you exactly where you are.
How does having an on-site Physical Therapist benefit me as a member?
This is what makes us the "360° Circle of Wellness." Having David J. Zwack, PT on-site means your fitness is overseen by clinical expertise. If you have a nagging injury or a movement restriction, our coaches work directly with our PT services to modify your workouts safely. It allows us to bridge the gap between rehabilitation and high-performance training, ensuring you stay injury-free while getting stronger.
What is a "Mayhem Affiliate" and how does the programming work?
Being a Mayhem Affiliate means we use world-class programming developed by the most successful team in fitness history. Every day, you’ll follow a structured "Workout of the Day" (WOD) that includes a warm-up, a strength or skill component, and a conditioning piece. These workouts are pressure-tested and designed to improve your functional mobility, power, and cardiovascular health in just one hour.
How does the 24/7 access work?
We know life doesn't always happen between 9-to-5. For members who want the ultimate flexibility, we provide personal keyfob access. This allows you to utilize our facility and equipment at any time of day or night, even when classes aren't in session. It’s perfect for shift workers, busy parents, or anyone who needs to fit their "360 wellness" into a non-traditional schedule.
