The Jianke develops Internal Power (內勁) -
Internal power comes from the ligaments and bones and is supported by proper alignment. In comparison with power generated by muscle alone, it is more springy and tenacious. In order to transmit this springy energy through the body, the muscles must be loose and unclenched. Being generated from a loose, soft, body, internal power is also faster and more penetrating than simple muscular, external force. The muscles being loose and unclenched allows for quick changes in direction, as they aren't hard or inflexible. Qi from the dantian can be combined with this springy method of generating power in a manner that helps improve the level of softness of the muscles that one can achieve. At a more experienced level, qi from the dantian add strength to the release of Internal power by combining qi with the spring of internal power.
