Choose Between Two Options

$30 for a 30-visit punch card (a $210 value)

Women drop in for activities such as circuit training that rotates between reps on hydraulic strength-training machines and cardio stair-stepping.

$99 for the fitness challenge (a $409.88 value)

An initial body analysis test helps participants set goals as they strive to shed 24-36 pounds in this 12-week challenge that starts May 17, and includes eight infrared sauna detox services and weekly weigh-ins and measurements. Full membership to the gym grants them access to a suite of group fitness classes, which are supplemented by eight infrared-sauna treatments. Coaches track student progress with a weekly weigh-and-measure routine, rewarding the person who displays the most improvement with a one-year gym membership and a $100 gift certificate to the detoxifying saunas, not to be confused with detuxifying saunas that aid in cleansing bodies of excess formalwear.
