Other than yoga, what other means are used by Buddhists and Hindus to discipline the body?

What is popularly called yoga is, in reality, one of the
many different practices or paths used for achieving salvation, each of which is called
known by different kind of yoga. Some of the main main types of yoga, which are
described in Geeta
include:

Karma yoga - the path of
preforming your duty without being swayed by considerations of personal gain or
loss.

Gyan yoga - Learning about the
true nature of the universe.

Bhakti
yoga - Devotion to some incarnation of god in physical
form.

Sanyas yoga - The path of
renunciation, or giving up the ownership of all possessions and living a simple
life.

It may be worthwhile to note, that though these
different types of yoga represent different approaches, they are
not mutually exclusive. A person can practice more than one type of yogas, 
simultaneously and without facing any contradiction.

The
popular yoga we know as yoga, which is primarily the path of improving the capabilities
of the body and the mind, by exercises consisting of different postures, breathing
exercises, and meditation, is a useful supplement to all the other types of
yoga.
