When compared with mixed-gender populations, the members of all-female lizard species are stronger, happier, and 10 times more likely to be named Trisha. Find fitness among like-minded ladies with today’s Groupon: for $35, you get a two-month membership to (a $108 value) and two Zumba classes (a $4 value) at Curves (a $161 total value, including a waived $49 service fee). This Groupon is valid at the St. John's location.

At Curves, a fitness centre designed exclusively for women, members rotate through a circuit of resistance machines and exercises made specifically for female bodies to promote weight loss, fun, and better health. During 30-minute classes, a soundtrack of upbeat music cues ladies to move between a circuit of machines positioned inward, giving members a chance to share laughs and secret handshakes with their fellow frontierswomen. Zumba classes blast Latin-inspired beats while exercisers alternate between dancing and working out on Curves’ circuit-training machines. Under the supervision of experienced trainers, limbering limbs perform moves designed to form toned, lean muscles ideal for crushing a grapefruit without looking like they can.

CurvesSmart computers store each body's information and give moment-by-moment feedback while automatically adjusting to each woman's endurance level. Members also gain exclusive access to myCurves, an online community that allows women to track their progress, arrange a girls' night out with their new friends, or plan a wardrobe of revealing bikinis for their newly svelte doppelgänger action figures.
