Questions? We Have The Anwsers
Whether you’re new to fitness or getting back into it, it’s normal to have questions. Here are a few we hear often—and our honest answers to help you feel confident starting with us.
1. Do I need to be in shape before I start?
Not at all. Our programs are designed specifically for adults over 40 who want to get in shape—not those who already are. Every workout is tailored to your current fitness level, injury history, and goals. We meet you where you are.
2. What’s included in the free consultation?
The No Sweat Intro is a 1-on-1 conversation with a coach—no workout gear needed. We’ll learn about your goals, past experiences, and any injuries, then explain how our program works and if it’s a good fit for you. No pressure, no sales pitch.
3. What if I have a previous injury or chronic pain?
That’s our specialty. We work with many clients dealing with knee pain, back issues, shoulder limitations, and more. Our coaches are trained to modify workouts so you can train safely, improve mobility, and actually feel better—not worse.
4. How is Catalyst different from a regular gym or fitness class?
We’re not a big-box gym or a one-size-fits-all class. At Catalyst, you’ll get personalized coaching, nutrition support, and real accountability in a welcoming environment. You’ll never feel lost or ignored here—and you’ll never wonder what to do next.
5. Do I have to commit to a long contract?
Nope. We start with a simple 3-month commitment to give you the structure and consistency you need to see results. After that, you’ll go month-to-month with just a 30-day notice. Our clients stay because they love the results—not because they’re locked in.
