The episode describes the Taijiquan principle of "empty armpits," a technique emphasizing relaxed shoulder and elbow positioning to protect the ribs and improve power generation.

This involves keeping the elbows close to the ribs without pressure, analogous to holding a steamed bun. The practice also promotes better qi and blood circulation, according to Traditional Chinese Medicine, benefiting the Heart Meridian.

This principle, while rooted in martial arts, offers health benefits through consistent practice.
