Expect detailed instruction; the teacher will provide modifications and variations to adjust the practice to the students' level of practice. We begin slowly setting intention, then we move into Sun Salutations to warm and activate muscle. We continue through the asanas moving the body into pose, counter pose to safely access the body and all systems.
“The main objective of Hatha yoga is to create an absolute balance of the interacting activities and processes of the physical body, mind and energy. When this balance is created, the impulses generated give a call of awakening to the central force, which is responsible for the evolution of human consciousness. If yoga is not used for this purpose, its true objective is lost.”
~Swami Muktibodhananda Saraswati, Commentary, 1985 translation, Hatha yoga Pradipika
"According to the Hatha yoga texts, each posture becomes perfect when the "effort disappears", one no longer thinks about the posture and one's body position, breathes normally per pranayama, and is able to dwell in one's meditation Yoga's combined focus on mindfulness, breathing, and physical movements bring health benefits with regular participation. Yoga participants report better sleep, increased energy levels and muscle tone, relief from muscle pain and stiffness, improved circulation and overall better general health" (Wikipedia)
"The breathing aspect of yoga can benefit heart rate and blood pressure."
