The Carol Bike offers five different hand positions and is designed to trigger a significant calorie burn through its intense Fat Burn workouts. These workouts consist of 60 eight-second sprints with 12-second recovery periods, lasting 17 to 25 minutes. While initially skeptical of the bike’s capabilities, the author quickly changed their mind when they experienced the challenging REHIT program, which is scientifically backed by a small-scale study. The bike is not for casual exercisers, but rather for those who are dedicated and want to maintain their fitness routine regardless of their schedule. After just two weeks of using the Carol Bike, the author noticed an improvement in their overall strength and performance. The bike allows for a minimum level of exertion to be achieved daily, making it possible to balance multiple forms of exercise. The author is now a believer in the Carol Bike’s effectiveness and is grateful for its ability to fit into their busy lifestyle.
