The user firmly plants both feet to the ground in a wide and firm stance, and then concentrates chakra in his feet to keep better grip of whatever surface he is standing on making it far more difficult to be pushed away. The user then readies his shield to recieve an incoming blow.
This Jutsu is especially effective against larger enemies and those of great strength who can send someone flying with a single punch. The user of this Jutsu would at most slide back from one such blow, assuming the strength difference isn't too big.
Benefits greatly from Physical strength
If the opponent has twice as much strength as the user, this jutsu becomes obsolete.
Blocking a powerful blow can leave the user's arm injured.
