As a gymnastics coach, Kaia FIT founder and owner Nikki Warren always noticed how children in motion tumble and play with ease. They were effortlessly agile and flexible, and yet many of them would grow into adults who would struggle to stay active. Kaia FIT sprang from this realization with the goal of restoring female physiques to the adolescent pliability everyone enjoys before they grow their rock-hard exoskeleton after sixth grade. In a welcoming environment, the expert coaches retrain bodies with dynamic workouts designed to strengthen muscles, boost energy and confidence, and vanquish fat. They root the sessions in functional training, a method that enlists athletes' own body weight and movement to stimulate fitness.

Programs range in intensity and length for exercisers of all ages, fitness levels, and goals, from six-week BRIK boot camps, which debut a fresh workout regime for each season, to Saturday Power Hours, which blend interval, strength, and endurance training. CORE Session boot-camp classes unfold in five-week intervals between BRIK camps and use muscle-confusion techniques to keep bodies in better shape than fad diets or preserving them in amber for swimsuit season would. The various regimens invite women to join a community where they dedicate themselves to maintaining their health and fitness.
