The first segment of this session is active back arches, with focus on the shoulders and arms. The work on the knee starts in the second half of the session, with preliminary visual diagnostics, and arranging the knees in the most basic and symmetrical asana position: Tadasana.
Those with actual knee pain may omit some of the back arches that aggravate their knee (omit between 23rd and 53rd minutes), and then start their practice from the second second of the session (min 53)
Medical science has advanced diagnostic tools for assessing knee condition. This session trains us to use our own eyes to be a diagnostic tool to not just diagnose well in advance so we can take corrective measures. This session is suitable even for beginners: both the diagnosis and the corrective actions are demonstrated simply and clearly.
