yoga is thousands of years old and is practiced by millions of Americans.
(See Reference 3) Most classes and routines draw from the same poses.
The few dozen or a hundred commonly used asanas are a handful compared
to the wealth of choices in the full yoga inventory. But the variety of
poses will give you a total fitness workout that strengthens, stretches
and relaxes you, whether you are flat on the floor in Corpse pose or
upside-down in Headstand.
