Standing asanas such as
Adho Mukha Svanasana (Downward Dog),
Virabhadrasana (Warrior Pose) and
Trikonasana (Triangle Pose) are a conspicuous feature of the yoga practised around the modern world. Nearly all the standing poses now practised were unknown in
hatha yoga until the 20th century. Many are described in Iyengar's 1966
Light on Yoga. Some, such as
Tadasana, appear in the 1896
Vyayama Dipika, a manual of
gymnastics, as part of the "very old" sequence of
danda (Sanskrit for "staff" or "stick") exercises.
Norman Sjoman suggests that it is one of the poses adopted into yoga in Mysore by Krishnamacharya and forming the "primary foundation" for his
vinyasas, the flowing movements between poses. The pose would then have been taken up by his pupils
Pattabhi Jois and Iyengar. is one of the most widely-recognised asanas. In 1924,
Swami Kuvalayananda founded the
Kaivalyadhama Health and Yoga Research Center in
Maharashtra. He and his rival
Yogendra began to combine asanas with Indian systems of exercise and modern European gymnastics, having according to the scholar
Joseph Alter a "profound" effect on the evolution of yoga. Krishnamacharya, known as the father of modern yoga, studied under Kuvalayananda in the 1930s and created in his
Mysore yogashala "a marriage of hatha yoga, wrestling exercises, and modern Western gymnastic movement, and unlike anything seen before in the yoga tradition."
Norman Sjoman argues that Krishnamacharya drew on the
Vyayama Dipika gymnastic exercise manual to create the Mysore Palace system of yoga. Sjoman further observes that whereas many traditional asanas are named for objects (like
Padmasana, lotus pose), legendary figures (like
Matsyendrasana, the sage
Matsyendra's pose), or animals (like
Kurmasana, tortoise pose), many of Iyengar's asanas have names that simply describe the body's position (like
Utthita Parsvakonasana, "Extended Side Angle Pose"); these are, he suggests, the ones developed in the 20th century. The yoga scholar
Mark Singleton argues that Krishnamacharya was familiar with the
physical culture of his time, which was influenced by Scandinavian
gymnastics such as the system of
Niels Bukh; Krishnamacharya's experimentation with asanas and his innovative use of gymnastic jumping between poses may well explain, Singleton suggests, the resemblances between modern standing asanas and Scandinavian gymnastics. since Singleton's 2010 book
Yoga Body argued that some forms of modern yoga represent a radical reworking of hatha yoga, in particular by adding standing asanas and transitions (vinyasas) between them, and by suppressing most non-postural aspects of
yoga, rather than a smooth continuation of ancient traditions. The addition of vinyasas enabled sequences consisting mainly of standing asanas to be practised in a continuous flow. Such a sequence could be performed quickly if desired, making for
aerobic exercise, possibly at the expense of a more
meditative practice. ==Surya Namaskar==
