For the past few years I have taken yoga and have realized the benefits go far beyond the exercise. After class, I feel better, sleep better, am more relaxed, want to drink more water, and usually want to eat healthier, too. Yoga physically helps with flexibility, strength, and balance. Mentally, it helps to cultivate a balanced lifestyle while emphasizing patience and acceptance for yourself and others.
Yoga Journal is a great place to start learning more about yoga.
For specific poses with pictures and step-by-step instructions:
Yoga Journal's Pose Section - benefits, tips, modifications, follow-up poses, and more!
Santosha.com - includes pose difficulty levels
Here are two blogs from Yoga Journal's Blog Section:
For the advanced -
Challenge Pose. Good luck with these crazy poses!
For everyone -
Top Five Tuesdays. The July 12th post, "5 Surprising Benefits of Yoga" would be good to inspire those who don't take yoga and the rest is good for any yogi.
I don't know Sanskrit! Yoga Magazine has a useful
glossary.
Om Shanti
