Frequently Asked Questions
How does the 15-minute start time work?
Classes begin at :00, :15, :30, and :45 past every hour. Simply book the time slot that fits your schedule and show up ready to train. This means you have multiple options throughout the day instead of being locked into one or two class times.
What if I can only workout for 30 minutes?
No Problem! You choose your workout duration: 15, 30, 45, or 60 minutes. Life happens, and we adapt. Get an effective workout in the time you have available.
Do I need any experience?
Not at all! Our coaches work with complete beginners to advanced athletes. Every exercise can be modified to match your current fitness level.
What's included in my membership?
All equipment, expert coaching, workout modifications for all fitness levels, daily warm-up and cool-down routines, progress tracking, and access to our supportive community.
Can I bring a friend?
Yes! Many of our membership tiers include guest privileges. Check our membership page for details on bringing friends and family.
What makes CORE XV different?
Classes start every 15 minutes, giving you way more flexibility than traditional gyms. Book your time slot, choose your workout duration (15, 30, 45, or 60 min), and train on your schedule. No more missing workouts because you can't make the one class time offered.
Do I have to share or wait for equipment?
Nope. Our workouts are designed so you never stand around waiting for equipment. Each training block is intentionally capped, stations are pre-set, and the flow keeps you moving the entire time—so every minute you’re here counts.

Clean facility. Top equipment. Welcoming atmosphere. This is where your transformation happens.
