Yoga has been practiced for thousands of years, yet is constantly being redefined. Yoga for Life introduces readers to five forms of this ancient discipline newly adapted to today’s lifestyles. Those looking for an energetic workout will go for Astanga or “power” yoga; those who need a gentler approach will appreciate Iyengar, Viniyoga, or Sivananda. Each of the four sections includes case studies demonstrating yoga’s real benefits.
