This technique is a refined application of the use of chakra flow to enhance the user's physical strength, if even for an instant. It is similar in practice to general skills such as walking on water, where chakra is instead channelled into the user's hands or feet to bolster an attack.
By applying this with the refined chakra control and concentration required in medical ninjutsu, one can enhance their strength to monstrous levels. By releasing the chakra stored into their hands or feet, and releasing onto the target with pinpoint timing, the user will be able to easily create gigantic craters in the ground or kill opponents with a single strike.[1][2] The training for this application is quite arduous, as Tsunade repeatedly came at Sakura with full force to help her learn.[3]
Trivia
- 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,[4] creating giant craters and fissures in an area by simply striking it with either her heel or finger,[5] destroying the ribcage of Madara Uchiha's Susanoo[6] and its sword[7], and sending opponents flying with a flick of her finger with relative ease.
