Kaia Fit, Reno

As a gymnastics coach, 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, along with the goal of restoring female physiques to the pliability everyone enjoys before they grow their rock-hard exoskeleton after sixth grade.

In a welcoming environment, 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 a person's own body weight and movement to stimulate fitness.

Programs range 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 Ten-week intervals between the BRIK boot camps and use muscle-confusion techniques to keep bodies in shape. This is purely a women only gym.
