Hatha Yoga is the root of all the different types of yoga. It is both a discipline in itself and the perfect base to Ashtanga and Vinyasa yoga.
The postures are thoroughly detailed and it allows you to learn the alignments and thus have a better understanding of your body. Breathing is also an essential part of Hatha Yoga.
Ashtanga Yoga is a dynamic flow of postures combined with breathing. This tradition comes from Krishnamacharya and was codified by Sri Pattabhi Jois in his book Yoga Mala. ashtanga yoga is composed of 5 series of postures depending on the skill level.
Vinyasa Krama, otherwise known as ‘moving by numbers’, is the tradition of practicing asana in a flowing sequence connected harmoniously by the breath. Krama means ‘a step’ or ‘in stages.’ It also means to learn the postures one by one, observing the correct order. Vinyasa Krama was also a phrase used by Professor T. Krishnamacharya to convey two different, though complementary approaches.
Pranayama is a discipline in itself based on breathing. In Sanskrit Prana means the energy of breathing. There are several types of Pranayama, each type has a different result on the mind going from relaxation to stimulation. Every class finishes with pranayama, usually with the Ujjai breathing which is the basic breathing. Pranayama soothes and helps refocussing. It also makes the postures easier. It is essential to Yoga.
