I grabbed this at my local library after seeing it from the corner of my eye. I’ve been doing yoga since last year at least twice a week. It has really helped with some chronic pains in my back and other places that I thought were just older age setting in. But after regular yoga these pains are gone for good. I feel a bunch better after a quick 30 minute session and complete rejuvenated after a good 60 minute session.
The Harvard Medical School Guide to Yoga is an excellent primer. Covers everything in depth. The best part is at the end where the authors have included an 8-week guide including sequences to get you going. This is a great place to start your yoga practice and will answer many of your questions.
This is a book to buy and keep as a reference if you have an interest in yoga. It earned 5 stars from me.
