Yoga is to the nineties as aerobics was to the eighties. There are similarities: both increase flexibility, both build strength, both develop muscle tone and both are a great excuse to wear something cute (if lycra G-strings were ever considered cute).
The big difference, of course, is that yoga offers something intangible. Possibly best classified under the umbrella of spirituality, it’s an innate awareness of our interconnectedness to the environment around us. To ensure that yoga doesn’t get Jane Fonda-rized, the Green Yoga Organization can help us to stay grounded to the true meaning of yoga.
