Inaccessible to the hands, back musculature often falls prey to freeloading Kick Me signs and hitchhiking parrots. Liberate a beleaguered back with today's Groupon to Imagos Day Spa. Choose from the following options:

Imagos Day Spa devotes 17 private rooms to luxurious facials, massages, and other deluxe spa services. A consultation session precedes each massage to determine clients' health histories, allowing Imagos' certified technicians to tailor sessions to muscles' individual needs. Listen to soft, relaxing music during each 40-minute Swedish massage—which lasts the same amount of time it takes a barge to pass another barge—while Biotone massage oil coaxes backs into absorbing every knot-busting pulse from technicians' nimble fingers. Or, choose from the "balancing," "calming," or "energizing," blends for each 50-minute aromatherapy massage, whose Swedish techniques unleash tension and mollify stubborn musculatures. Imagos Day Spa blends its own aromatherapy oils, such as lavender, orange, and peppermint, to create distinct scents for each massage experience.

Clients can also don leis in a room decorated with flower garlands during specialized 50-minute Hawaiian Lomilomi massages, whose tension-zapping strokes, like the entire discographies of Metallica and Yo-Yo Ma, are inspired by the cadence of ocean waves. Coconut oil hydrates skin and lends a tropical scent to the air while the tissues below succumb to the session's calming tides and the room's sea-shanty soundtrack. Relax before each appointment with a complimentary cup of coffee or juice, and duck into one of the gender-separated locker rooms, where comfortable seats welcome waiting clients.
