At InstaPhysique, with studios in Sacramento (Arden & Midtown) and Roseville, our mission has always been simple: help busy people live healthier, stronger lives—without wasting time. That’s why we’re excited to introduce something revolutionary to our community: CAROL Bike, the world’s first AI-powered exercise bike designed for REHIT (Reduced Exertion High-Intensity Training).
If you’ve ever thought, “I don’t have time for cardio”—this is for you.
What Is REHIT?
REHIT is the smarter, science-backed evolution of HIIT. Instead of spending 30–50 minutes doing cardio, REHIT condenses the same (or even better!) cardiovascular and metabolic benefits into just 5 minutes.
Here’s how it works:
- A CAROL Bike session includes just two 20-second sprints, personalized to your fitness level.
- These sprints deplete your muscles of stored sugar (glycogen) in a way traditional workouts can’t.
- The result? You trigger powerful health adaptations that improve your cardiovascular fitness, insulin sensitivity, and fat metabolism in a fraction of the time.
Why CAROL Bike at InstaPhysique’s Sacramento & Roseville Studios is a Game-Changer for Longevity Training
We know your time is valuable. Many of our members juggle careers, family, and packed schedules—and that’s exactly why InstaPhysique exists: to give you the most effective workouts in the least amount of time.
- Our Megaformer classes give you a full-body strength, endurance & zone 2 cardio workout in just 40 minutes.
- Our recovery services (sauna, lymphatic roll massage) help you maximize results without burning out.
- And now, CAROL Bike adds a game-changing cardio option: just 5 minutes for massive returns on your health.
Here’s what makes CAROL truly special: clinical studies show that just 8 weeks of riding CAROL improved VO2 Max by 12%, a dramatic gain in cardiovascular fitness and one of the strongest predictors of longevity.
At InstaPhysique, we’re not just about short-term fitness, we’re about training for the long haul. That’s why we’ve built our ecosystem around tools like metabolic testing, low-impact strength training, and now REHIT with CAROL Bike: every piece works together to improve your performance, recovery, and ultimately, your healthspan…the years you live feeling healthy, strong, and capable.
It’s not about working harder or longer. It’s about working smarter and giving your body what it needs to perform at its highest level for years to come.
Why You Should Book a Session & How to Book
Think of CAROL as your “health hack” bike. Just a few sessions a week can:
- Improve your VO2 max (a key marker of longevity and cardiovascular health).
- Burn fat more efficiently, even after you step off the bike.
- Free up time so you can spend it on the things that matter most, while still hitting your health goals.
Yes, it really is just 5 minutes. And yes, it really works.
CAROL Bike sessions are now available to book using your class credits (1 credit = 2 CAROL sessions). Single CAROL sessions & packs are also available for purchase. Whether you want to pair a ride with your Megaformer workout or pop in on a busy day and do it alone or pair it with a Sauna or Roll session (even better!), the CAROL Bike makes it easy to stay consistent.
Because at InstaPhysique, we believe your health shouldn’t have to wait until “when you have time.” With the right tools, you can get results smarter, faster, and more efficiently.
