Though most spa services are relegated to the body's frontal regions, the back's quiet, dignified tolerance of "kick me" signs has proven it more deserving of appreciation. Acknowledge your underdog with today's Groupon: for $39, you get a 60-minute Blissed Out back treatment (a $115 value) at The Spa on King in Oshawa.

The healing hands of The Spa on King's experienced and friendly aestheticians work in tandem with Dermalogica noncomedogenic products to refurbish backsides to the glow of their newborn glory days. After staff members polish posteriors with a deep-cleaning steam, they enlist an exfoliating cleanse to evacuate clogged pores and evict other deadbeat epidermal invaders. Backs buckling under the weight of the world relish the luxurious lather of an oil-free aromatherapy massage, delivered by warm basalt river stones that lull torsos into dreams of a world without herniated discs or regrettable tattoos. After pampering patrons' areas of concern, technicians apply a coat of oil-free moisturizer to help seal the satiated spine shells and ward off drying agents.
