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 likeminded ladies to increase fitness, morale, and results: for $19, new clients get a one-month membership that includes the initiation fee, a fitness assessment, a weight-management consultation, and two Zumba classes at Curves (a $137 total value). Today's Groupon is valid at one of six locations in Deland, Flagler Beach, Port Orange, Orange City, and Ormond Beach.

With machines set up in rows to encourage competition, many ordinary gyms cater to men's bodies and psychology, right down to the urinals that were "accidentally" installed in the women's locker room. A Curves membership ($93 including start-up fee) sends you around a circuit of hydraulic resistance machines that have been designed to work with women's bodies and promote weight loss, protect against osteoporosis, and deal with arthritis. An experienced trainer is always nearby to help manage machine maneuvering and muscle making. Because traditional lift-and-lower motions create bulky muscles, each hydraulic machine uses push-and-pull motions to maintain momentum and create toned, lean muscles perfect for crushing a grapefruit without looking like you can.

Using the CurvesSmart personal coaching system ($25), each thigh or torso transformer is programmed with information about a fitness seeker's weight, endurance level, and fitness goals to automatically calibrate the perfect challenge for her bod and deliver a postworkout rundown on the progress achieved during her session. For a dose of human-delivered health help, new members will meet with professional shape sherpas for a 60-minute fitness assessment and weight-management consultation. They'll also receive a weight-management guidebook ($15) to aid in planning meals and stave off boredom while waiting for the Easy-Bake Oven to release a nutritious snack.

Zumba workouts ($2 each) add energetic Latin-flavored moves and music to the traditional 30-minute Curves circuit, alternating mini personal dance parties with intervals on strength-training and cardio machines to raise your heart rate and burn calories. Meet new friends and plan a girls' night out between labored breaths, or invite along some of your current friends as friends instead of as shields against the creep ogling you at the juice bar.
