Back Bends –
“Asanas penetrate deep into each layer of the body and ultimately into the consciousness itself.” by B.K.S Iyengar. 體式滲透到身體的每一層面，最終進入意識本身。

Urdhva Dhanurasana – 上弓式 「 strengthens 強化部位：abdominal 腹部肌群 、 pelvic organs 骨盆帶肌群 」

Your body arches back to form an extended bow in this asana. Urdhva means “upward” in Sanskrit, while dhanur translates as “bow”. Regular practice of Urdhva Dhanurasana keeps your body supple, and creates a feeling of vitality and lightness. The asana stimulates the adrenal glands, strengthening your willpower, and increasing your capacity to bear stress.

當身體向後彎曲時，在此體式中則形成一個延展的弓形。 Urdhva在梵語中的意思是“向上”，而dhanur則翻譯為“弓”。 定期練習Urdhva Dhanurasana可使您的身體保持柔軟，並帶來活力和輕盈感。 該體式刺激腎上腺，增強意志力，增強承受壓力的能力。 by B.K.S Iyengar
