Final answer:
In hot vinyasa yoga, prana is primarily built during Sun Salutations, which are dynamic sequences that generate heat and energy in the body. While backbends and inversions may also contribute to prana building, Sun Salutations are the main component for this in hot vinyasa.
Step-by-step explanation:
The concept of prana is important in the practice of yoga, particularly in hot vinyasa yoga. Prana is often referred to as the life force or vital energy that sustains life and flows through all things. In the context of hot vinyasa yoga, prana building is associated with movements and breath that stimulate and increase energy flow.
Regarding the choices given in the question, prana is built during the active parts of the practice, where movement is synchronized with breath. Therefore, the correct answer would be B) During Sun Salutations. Sun Salutations are dynamic sequences that generate heat and build energy in the body, which in turn cultivates prana. Other practices like backbends and inversions can also build prana, but they are not the primary focus in hot vinyasa yoga for building prana as Sun Salutations are.
Savasana, or corpse pose, is more about relaxation and integrating the benefits of the practice rather than building prana. It's a time for the body to cool down and for the mind to absorb the effects of the practice.
