5 Plush private gyms

$24,000 a year for a resident membership, plus $200 monthly dues

The prestigious Houstonian Club, along with the Houstonian Hotel and Trellis Spa, is located on 18 gated acres in the heart of the city. But don't let the elegant, old-school lobby fool you. The 125,000 square-foot facility features over 300 pieces of top-of-the-line exercise equipment, three pools, a track, a rock climbing wall, boxing ring and Pilates studio as well as eight tennis courts, a full court gym for basketball and volleyball and over 100 group exercise classes per week.

Resident members, who are mainly executives and public figures, also enjoy a private workout space and changing area, in addition to use of the club's boardroom and library as well as free childcare. And if they decide to hit the spa for some good, old-fashioned pampering they'll get 20% off.
