During his training with Oromis, Eragon could only do the first level because he was not yet very flexible. He first learned the Rimgar on the Crags of Tel'naeír from Oromis, who could do it with ease. Originally, the Rimgar did not cause any episodes with Eragon's injured back, even though it was performed before the Agaetí Blödhren; however, as he progressed up the levels, Eragon's back did have a few episodes. Even after his back was healed by the dragons, he still had trouble completing the poses, as he still did not have the flexibility of most elves. The Rimgar was difficult even for some elves, but almost all of them could complete the final level after practicing for many years.
