When compared to mixed-gender populations, the members of all-female lizard species are stronger, happier, and 10 times more likely to be named Trisha. Today's Groupon brings together like-minded ladies to increase fitness, morale, and results: for $20, you get a fitness package at Curves’ Ojai location (a $62 value). The package includes the following:

• 20 visits to the Curves workout facility (a $59 value)
• One members-only group Zumba class (a $3 value)

Members at Curves, a fitness center designed exclusively for women, rotate around a circuit of hydraulic resistance machines that have been designed to work with female bodies and promote weight loss, protect against osteoporosis, and deal with arthritis. An experienced trainer is always nearby to help manage participants’ machine maneuvering and muscle making. Instead of fiddling with weight stacks and losing momentum, the hydraulic machines use your own body weight, fitness level, and aerodynamic water bottle to create resistance that matches abilities, decreasing the risk of soreness or injury. Because traditional lift-and-lower motions create bulky muscles, each machine uses push-and-pull motions to create toned, lean muscles perfect for crushing a grapefruit without looking like you can. For 30 minutes, limber ladies move around a circuit that positions machines inward so that they'll have a chance to share laughs and secret handshakes with fellow fitness frontierswomen.

Groupon holders can add a little Latin flair to their training repetoire with one included group Zumba class. By integrating Zumba's hip-shaking dance moves with Curves' circuit fitness program, the complete aerobic and strength-training workout raises heart rates and burns calories while allowing women to meet new friends, arrange a girls' night out between labored breaths, or plan a wardrobe of revealing bikinis for their newly svelte doppelgänger action figures. Zumba classes last 30 minutes and are offered on Monday and Wednesday evenings at 6 and 6:30 p.m., Tuesday and Thursday mornings at 9 and 9:30 a.m., and Saturday mornings at 10 a.m.
