How it started
Marshall first heard about CAROL through a friend in the biohacking world:
“I first heard about CAROL from a friend, Jim Keen, who helped launch another great state-of-the-art fitness tool, the ARX.”
As the owner of a strength training studio, Marshall was looking for a high-intensity cardio machine that delivered measurable results, without burning hours each week. After listening to a podcast featuring CAROL co-founder Ulrich, he visited a local studio in Chicago and tried CAROL Bike for the first time.
“After one ride, I was convinced! I loved how easy it was to learn, super efficient, safe, and quick results. The quantifiable information from each ride was inspirational. I could not wait for my next ride.”
The results: “My doctor was blown away.”
Marshall has been using CAROL Bike since the summer of 2020, almost 5 years and counting.
What’s changed? Everything.
“Amazing results! I’m 76 years old and in the best shape of my life.”
The real validation came during a recent cardiac assessment:
“I just did an echo stress test and the doctor and techs were blown away with my results. My heart is clean and tough!”
For Marshall, CAROL Bike is both a fitness and longevity tool. A way to stay strong, resilient, and biologically young while staying “in his lane.”
His go-to workout?
“REHIT Intense.”
5 years later and still like new
CAROL Bike is engineered to last, and Marshall is living proof:
“The price was VERY reasonable and quality is excellent. 5 years old now and looks brand new. I have had ZERO issues.”
Setup was just as smooth:
“Easy delivery. Set up and install in less than 90 minutes. I did it by myself!”
And his enthusiasm hasn’t faded:
“BTW… CAROL KICKED MY ASS AGAIN TODAY… and in 8 minutes 40 seconds!”
His advice to new riders
Marshall doesn’t hesitate:
“DON’T THINK ABOUT IT, JUST GET IT!!! You will not be disappointed.”
And for anyone who claims they don’t have time to exercise:
“They are only fooling themselves! Get a CAROL Bike and stop complaining ever again. Plus, you’ll look and feel better than ever!”
Bottom line?
“I LOVE CAROL.”
