Pure Progress (純粋なる成長 Junsui naru Seichō) is a growth (成長 Seichō) ability one uses when facing an opponent stronger than they are, allowing them to instinctively improve their prowess the longer they fight.
For some (like Hit), this ability allows one to imprint on their experiences to, while not growing in power level, energy, physical strength or conditioning, allows them to adapt and instantly improve their performance and skillset. For others (like Ganos), the exact opposite is applied; their methods in battle remain unchanged while their sheer strength and speed will steadily increase in very short periods of time.
This ability is only displayed in the Dragon Ball Super anime.
In the Tournament of Destroyers, as Goku anticipates Hit's battle tactics to counter his 0.1 second Time-Skip, a pressured Hit was forced to adapt. While seemingly overwhelmed by Super Saiyan Blue Goku, the assassin revealed to have doubled the Time-Skip limit to intercept Goku. Hit then instantly adjusted his fighting style to maximize the usage of Time-Skip, which allowed him to advance his Time-Skip to 0.5 seconds, letting him to launch a barrage of strikes before Goku could react. Once Goku overwhelmed Hit with his X10 Super Saiyan Blue Kaio-ken, Hit improves his Time-Skip into a complete freezing of time, letting him dodge Goku's match ending punch. In the manga Hit never needed to improve his Time-Skip beyond 0.1 seconds, as he could already increase the time beyond 0.1 seconds whenever he wanted to.
By the Tournament of Power, the blazingly fast Dyspo who could detect and react to one's attacks simply from hearing the muscle movements made it difficult for Hit to use his Time-Skip. Despite the initial one-sided assault from Dyspo, Hit continue to adapt to the Pride Trooper's attacks, effectively blocking the critical strikes while letting the lesser ones land to better adapt. Later, against the Jiren the strongest being in Universe 11 with Destroyer-like might, Hit's continued adapting allowed his body to memorize the timing of Jiren's counters, eventually allowing him to land a single blow on the Pride Trooper.
Ganos' straightforward attack style and sole dependence on raw might initially allowed Master Roshi to easily analyze and anticipated Ganos' attack patterns, effortlessly countering the assault. However, as noted by Quitela, even mere minutes of struggle would cause a noticeable increase in power. This was proven as gradually, Ganos's sheer speed and power proved grew too much for Roshi to keep up with. When Roshi attempted to use his Sleepy Boy Technique on the foe, a desperate Ganos badly injured himself to escape the hypnotic effects, noting that an even a few minutes ago he would not have lasted long enough. Despite Ganos' injuries, Ganos' increased might enabled him to still fight on.
While in the Ultra Instinct -Sign- state, Goku's power and efficiency both increase at an alarming rate as he continues to fight against a foe of comparable or greater power to himself. The gods of Universe 11 are astounded that Goku is able to gain on Jiren so quickly as he gradually begins to overwhelm Jiren before his untimely regression to base form. Upon completing Ultra Instinct, Goku retains this abillity, only it is much more powerful.

— Dragon Ball Xenoverse 2 Awoken Skill description
Hit's Pure Progress seen in the anime appears and receives a name in Dragon Ball Xenoverse 2 as an Awoken Skill "transformation". Hit can go through his Pure Progress twice, and as in the anime his stances change, so does in the game, becoming stronger in each one. After the 1.09.00 Update, Pure Progress appears as Hit's Awoken Skill in his custom skillset by default, though it can be unequipped via Partner Customization.
- Vegeta likens this to the Saiyans' own natural ability to grow and develop, to which he was very annoyed that Hit's growth rate seemed to exceed that of the Saiyans'. Roshi also notes that Ganos' ability to grow is troublesome, and that he could become a threat to even Goku and the others.
- Due to this technique increasing the power and speed of a user every second, it's unknown if this technique really has a limit to the amount of power able to be increased.
