AFAA-certified fitness instructor Kari Fundingsland did three decades' worth of research before opening Kari Kardio. Beginning with her first Jazzercise center in 1983, she amassed group- and personal-training knowledge at gyms stationed from the United States to Australia. She took note of club fads and their effects, and experimented with different exercise styles to create the Kardio Flex System—a malleable workout template that allows instructors to pair her proven exercises with their own music playing over speakers or inside their heads. Today, more than 30 group classes per week at Kari Kardio attest to the breadth of her industry savvy.

With backgrounds in competitive athletics, personal training, and other high-level fitness activities, Kari Kardio’s teachers pair time-tested training methods with the latest workout trends. Their classes—which run the gamut from spin to kickboxing to strength training—accommodate all experience levels with safe exercise modifications. Treadmills and stationary bikes line the 9,000-square-foot studio, helping students chase their fitness goals and complete stationary paper routes when not attending classes.
