Roughly 85% of New Year's resolutions never make it past the hypothetical phase, according to an unfinished study that was abandoned in early February. Prove the stats wrong with today's Groupon: for $20, you get 20 women's fitness classes at Lady of Livingston in Brighton (a $180 value).

Lady of Livingston's seasoned trainers guide groups of women toward toned physiques with a flexible schedule of beginner, intermediate, and advanced fitness classes. Infusing melodic Latin moves into every session, Zumba challenges participants to swivel their hips and rock out on air maracas to the beat of sultry dance tracks. Meanwhile, Basic Step classes integrate a variety of choreographed aerobic exercises, and high-energy sessions of Sweat-N-Chisel utilize alternating intervals of strength and cardio training to evict invasive fat cells from their protoplasmic digs. Focusing on both mind and body, yoga and mat Pilates encourage participants to submerge themselves in spiritual tranquility as cadenced movements aim to build core strength, increase flexibility, and reconnect shadows to their estranged owners. Spinning classes require an additional $5 fee.

Classes are held in an expansive studio, which allows fitness seekers to safely use a variety of equipment and keep an eye on their devious doppelgangers in capacious floor-to-ceiling mirrors.
