A Saiyajin can multiply his power if he takes great damage or is near death and is able to heal himself afterwards.

With that ability alone, they could rinse and repeat countless times before the first encounter with the Androids (you can't be too safe).

Goku and Vegeta have their pride and all, I get that. But Trunks and Gohan are much more rational (especially Future Trunks). So why didn't they do what Vegeta did on Namek with Dende for example?

There are multiple things against this.

  1. It needs a close death experience to gain power and they need to be healed afterwards, as Dende wasn't on earth at this time and they surely don't want to eat all the beans. It would take a lot of time to regain their full strength and they could die trying of course.
  2. Vegeta and Goku would never use something like that to gain power because of their pride.
  3. They might have underestimated the cyborgs
  4. Future Trunks was not in this timeline on that time
  5. Gohan was a kid at this time and he "had to study". His mother would have never allowed him to be beaten half dead and recovered just to increase power.

6. Future Trunks might not be aware of this fact, since when he lived Goku and Vegeta were already dead and Gohan might never told him that.

As Exception from 2:

Vegeta did this on Namek cause he hated Frieza, he destroyed the planet Vegeta and killed nearly all the Sajyans. (As exception of 2.)

Those are the reasons against, it in my opinion. There might be more, and some might not be right, but I hope you can use this answer.

    Also, it would make the series rather dull if it were to happen that way. So the mangaka didn't do it that way :) Dec 18, 2012 at 15:27
  • My to that answer is too long to the comment so please read this: gist.github.com/4331770 Dec 18, 2012 at 20:46

  • @Tartori OK, 1.So they could do it before the cell games at least. Logically, Everything else it total guess of yours. unless you give me hard evidence. Dec 18, 2012 at 21:45

There was also the possibility they could have died while trying this, so it's not such a good strategy.

    Come on, seriously? With dende on their side they can literally make a hole in their stomach and still live for incredibly long time, Then heal themselves. Aug 3, 2013 at 21:09

First things first

  • Goku use in the spaceship, while going to Namek. (Seeds)
  • Vegeta ask Dende to help him with it in Namek. (Heal)
  • Gohan get power up thanks to the Old Kai. (Without getting damage, only releasing the hidden power)
  • Trunks and Goten never needed the power up (they used only the SSJ 3 form to do this)

The Androids appearance

Three years have passed since the visit by the mysterious Future Trunks. Goku, Piccolo and Gohan leave to go and face their destiny against enemies they have only heard about, but not seen. They are as prepared as they could be, though Piccolo wishes they had more time to become stronger.

The point that need to be considerate here is: You need to train your technique not only your power (check out how boxers or others professional fighters train before a fight)

  • There is no connection between what you said and what I wrote. And if you follow the comments written under the Tartori answer You will see that they had more than one chance to do so. In addition to that, By simple logic, When you are strong significantly from someone else, There is no meaning to the technique. Dec 21, 2012 at 18:44

    1. "When you are strong significantly from someone else, There is no meaning to the technique." The idea of teaching the weak to defeat the strong is an ancient tradition in the martial arts. The art of tai chi, for instance, in its original form as a fighting style rather than a health exercise, was supposedly developed so that a weaker fighter could learn to prevail over a stronger one through intelligent tactics.

  • 3. use the CHAT for discussion/debate. 4. My answer is about WHY they prefer to train their skills over their power. 5. Try keep the comments inside the stackexchange sites. Dec 21, 2012 at 18:53
  • Many, many years before, when Goku and Krillin were kids and were training under Master Roshi, he told them they had reached the top of their skills, and they could only improve becoming stronger, faster and more resiliant.
