Unity Woods Yoga's founder and chief instructor, John Schumacher, studied in India with B.K.S. Iyengar, one of the world's foremost yoga teachers. His team of friendly, enthusiastic instructors is fully certified and knows 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. With four passes, body benders can drop-in for any class in level I, level I/II, gentle I or II, seniors, or stop by for the four-week introductory yoga course. Classes take place several times a day, seven days a week at the clean, accommodating downward-dog dens. Level I and I/II classes introduce students to the Iyengar approach, which emphasizes proper alignment and incorporates props to aid in postures that might otherwise be unachievable.

Yoga stretches your muscles, relieving stiffness and pain, and it also increases flexibility and strength. Deep core muscles support each pose, toning regions that will improve your range of motion, balance, and posture, which are all vital to moving up in the corporate world, seeing over the steering wheel, and slicing your morning bagel.
