The side crane pose is classified as an arm balance asana. This is a challenging pose and is thus categorized as an advanced level asana. The side crane pose must only be performed once the beginner and intermediate level yoga poses have been thoroughly mastered. Attempting the side crane pose without adequate yoga practice raises the probability of suffering from muscle strains, cramps and injuries. Practice the Pasasana and Marichyasana I as preparatory poses before you attempt the side crane pose.
