The body is a temple that must be maintained and respected, not converted into a terrifying shrine of Twinkie-worship. Respect your divine confines with today's Groupon: for $75, you get five Pilates group classes at Sky Frog Studios in Corte Madera (a $150 value).

Sky Frog's experienced strength-smiths flit across the polished wood of the studio's brand-new digs, forging muscled paragons of well being. Frolic through the schedule’s brawn-sculpting smorgasbord of one-hour courses, then prepare to melt calories like a butter sculpture of Colonel Sanders. The intimate, three- to four-person classes promote the performance of elegantly muscled sonatas with maximum input from Sky Frog’s knowledgeable instructors. Wall-mounted springboards reinvigorate humdrum Pilates routines with targeted core training and stimulating speeches directed at slacking sinews. Build the flexibility necessary for competitive gesticulation in the hospitable studio, which welcomes students of all levels of athleticism, experience, and krumping ability.
