“CAROL, there is no substitute.” - Jeremiah’s story, 8 weeks in

It started with a YouTube rabbit hole

Jeremiah wasn’t looking for a CAROL Bike specifically. He was researching exercise bikes—when he landed on Garage Gym Reviews. Lindsay’s breakdown of CAROL Bike stopped him in his tracks.

“Lindsay’s review prompted me to dig deeper into the product and company. I was sold within the first few hours.”

A few compelling client testimonials later, he’d made up his mind.

“I purchased without hesitation.”

What he was looking for

Jeremiah’s interest wasn’t casual. He was already deep into a longevity-focused fitness routine—weight-lifting, pilates—and actively looking for a cardio protocol that could earn its place alongside them. CAROL’s REHIT program gave him exactly what he needed.

“CAROL’s value proposition, specifically the REHIT program that promised an ultra-fast and results-driven workout.”

8 weeks later

The numbers tell the story.

In just 8 weeks, Jeremiah:

• Raised his VO2max from 44 to 52.4—a 19% improvement

• Lowered his average resting heart rate from 51 to 45 bpm

• Improved his sleep quality

• Shortened his recovery time from weight-lifting and pilates

A 19% VO2max improvement in 8 weeks is, by any measure, extraordinary. Research suggests that kind of increase is the equivalent of turning your biological age back by more than a decade.

The workout that works

Jeremiah uses the workout unique to CAROL Bike—REHIT.

“I use REHIT exclusively 3–4 times per week. I have not yet tried other programs as REHIT fits perfectly within my longevity-focused exercise program.”

That’s 15–20 minutes a week. Perfectly calibrated to him. With results that compound week on week.

Riding for the long term

Most riders say they can feel the difference within the first few weeks. Jeremiah felt it too—and he’s already thinking about what comes next.

“CAROL entered my life approximately 8 weeks ago and I intend to ride it for the long term.”

His response when asked what he’d say to those considering CAROL Bike?

“It’s a no-brainer purchase where no other exercise bike can match its capabilities. CAROL, there is no substitute.”
