我們徵求 Joe Chang 同學同意，分享這三張照片，因為 Joe 他有做到 Utthita Parsvakonasana 側角伸展式 的幾個要點喔：

(1) 屈腿時，保持坐骨等高。
(2) 屈腿的小腿垂直地板。
(3) 保持胸腔向前。
(4) 保持胸腔寛閱。
(5) 不要將所有重量全部壓在彎曲的腿上。
(6) 從右腳到右手在同一直線上伸展。

Joe 他其實不需要使用輔具，但我們仍然請他示範使用輔具，有些同學需要使用輔具讓身體回到正位：
(1) 左膝前側頂磚，讓小腿垂直地板。
(2) 右手手指碰牆，是要讓胸腔保持寛閣，並讓右手保持向上延伸並讓脊柱右腿來到同一條線上。
(3) 左手下扶磚，讓身體重量不要太過來到左腿。
