Fit To The Core, Johnston

Joan Kallen knows that when it comes to fitness, sometimes people just need a push in the right direction. That's why she founded Fit to the Core, where she motivates clients to get in shape via Pilates exercises, plyometric drills, and resistance training. A strength and cardio interval class rotates running on a treadmill with swinging a kettlebell, while an Insanity class relies solely on resistance created by the weight of one's own body and its shadow.
