If a career delivering pizzas to pizza deliverymen has you feeling tense and tightly wound, today's Groupon has the serenity solution your life is lacking: for $45, you get a one-month unlimited pass to Source Yoga (a $105 value). The North End yoga studio offers more than 20 classes a week for various skill levels to help you achieve Elongated Man flexibility and inner peace. Source Yoga's summer schedule starts May 1.

Source Yoga's friendly, enthusiastic instructors are fully certified and know how to help students sweat and stretch until they're calmer, more energized, and more revitalized than the 217 rechargeable AA batteries that power Greater America. If you're new to yoga, this is a great chance to learn the downward dog, the upward dog, and the omniscient narrator. Yoga stretches your muscles, relieving stiffness and pain; it also increases flexibility and strength (deep core muscles support each pose), which will improve your range of motion, balance, and posture, all vital to moving up in the corporate world, seeing over the steering wheel, and slicing your morning bagel.

The welcoming studio's class repertoire features standard yoga classes as well as specialized classes such as prenatal and postnatal mommy and baby yoga classes, so you can set your young'un on a path to enlightenment and good posture in a comfortable, encouraging environment. Buy this deal to treat yourself to a month of woman-powered introspection or gift it to the stressed mail carrier in your life and watch as they morph from a harried state of disheveledry into a state of tranquil stoicity.
