What is a common risk associated with performing the swan on the barrel?

When performing the swan on the barrel, the primary concern is the potential for shearing forces on the lower back. The movement involves extending the spine, which can place excessive strain on the lumbar region if proper technique, alignment, and body awareness are not maintained. If the pelvis is not stabilized or if there is an imbalance in muscular engagement, it can lead to unwanted movement of the lumbar vertebrae, resulting in shearing forces that may cause discomfort or injury.

By ensuring that the core muscles are actively engaged and that the movement is initiated from the thoracic spine, rather than forcing the lumbar spine into extension, individuals can help mitigate this risk and promote a safer practice. Awareness of maintaining alignment and focusing on controlled, fluid movements is crucial for preventing these types of stresses while performing the swan on the barrel.
