On the court or in the water, Boise Racquet & Swim Club gets people exercising. The facility hosts 23 tennis courts?almost evenly split between outdoor and indoor?and an outdoor swimming pool. After warming up on one of the fitness center's treadmills, ellipticals, or stationary bikes, you can duck outside for a few quick laps in the crystalline water or test your endurance against friends in both competitive and noncompetitive swim matches. Head to one of the courts to engage in some volleys, building hand-eye coordination and a lightning serve as you rocket the neon-yellow ball across the net during tournaments or lessons with tennis pros. For those who need a stricter routine to stick to a workout, the club also hosts group fitness classes in yoga, aerobics, and circuit training.
