The weathered wooden beams of vaulted ceilings tower above groups of exercisers in Art of Fitness. As serene as the spa it's a part of, the studio fills with sunlight and views of the Pacific ocean, making the lofty, blue-walled space bright and airy as guests meditate in yoga classes or shed outdated notions of progress on stationary bikes. An outdoor patio and neighboring spa offer tranquil respite from muscle building as children frolic in the childcare center.

As serene and impressive as the interior is, it's the staff of personal trainers that stands out. The team is a certified bulwark of track-and-field stars, Brazilian dancers, boxers, and neuromuscular massage therapists, all pooling their wildly disparate backgrounds to help guests blast past plateaus and slim silhouettes.
