Spinal Engine & Waist Power from Taijiquan Viewpoint

The myriad muscle actions of body segments have to be harmonized to produce motion of unified momentum underlying maximal waist power. Critical is the harmony of the torques at the waist-groin region, namely, that at the hip-joints of the pelvic movements and the spinal torsion. The practice solution to cultivate this harmony is forged by Taijiquan's principle of centrality that sorts out the multitudes of muscles in their functional roles of core-stabilization, postural control, and propulsion, as well as breathing, and allows them to balance and align accordingly. As it turns out, the centrality principle of yin-yang theory mirrors the SIJ hub in the transfer of forces between the upper and lower body through the three levers, the spine and the legs via the pelvic platform. All these must pay heed to the spinal engine.
