Chakra Enhanced Strength

By focusing chakra to the their hands or feet, the user attains "monstrous strength". This is done by releasing the stored chakra onto the target with pinpoint timing. This strength allows the user to easily make gigantic craters or kill opponents with a single strike. The training for this technique is quite arduous, as Tsunade repeatedly came at Sakura with full force to help her learn.

Trivia

 * While some may see it as merely superhuman strength, this technique is actually an application of medical ninjutsu that demands excellent concentration and chakra control.
 * It should be noted that unlike Sakura, Tsunade herself already possesses incredible raw strength, capable of crushing stones in a single hand with nothing but pure muscle power. This strength is later increased to monstrous levels, allowing her to perform feats like lifting and swinging Gamabunta's tantō, creating giant craters and fissures in an area by simply striking it with either her heel or finger, destroying the ribcage of Madara Uchiha's Susanoo and its sword, and sending opponents flying with a flick of her finger with relative ease.
