Spectrum Athletic Club, Santa Clarita

For more than three decades, locally owned Spectrum Athletic Clubs have aimed to create a resort-like experience for patrons with upscale perks and personalized care. After workouts, gym-goers can avail themselves of unlimited towel service and change in comfortable locker rooms. Other amenities include saunas, steam rooms, healthy cafes, specialized workout areas, and complimentary Internet access.

In addition, racquetball courts let athletes improve their game independently, and patrons can sweat solo on cardiovascular equipment with individual viewing screens. Group classes, more than 1,200 of which are held daily, include Zumba, Pilates, Body Combat, and CXWorx sessions and enable trainees to draw motivation from each other or from each exercise studio's complimentary tank of moxie. The Spectrum Kids Club gives kids a place to play while adults work out and hosts such events as pool parties and pizza parties throughout the year.
