@othus12: DBZ characters can and make their physical attacks nearly as strong as their ki blasts by amping it with ki:
For example Piccolo Daimo puts all of his ki in a blast to nuke a city. Then Goku puts all of his ki into his fist to tear through Piccolo.
Then 23rd budokai Piccolo puts all his ki in an explosion to nuke an island. Then Goku puts all of his ki into his body in otder to lay the smack down on Piccolo.
Although the Piccolo's ki blasts look more impressive Goku's direct and very potent ki punches and kicks have just as much power as he's punching/kicking with the same amount of ki which would be able to destroy a city/island. This is what DBZ characters do all the time also Nappa himself demonstrated this:
[img]Keep in mind that Nappa has enough ki to easily lay waste to a country so just imagine how powerful his ki punches are.[/img][/spoiler]
Using ki to bypass their physical limitations immensely is why DBZ characters have feats like casually jumping into the troposphere (21st budokai Goku) and casually throwing pillars accross the globe. (Tao Pai Pai) Toriyama himself confirmed this in an interview:
When it comes to battle, the most important thing is ki size, and its control. Of course, “ki” also includes such spiritual power as energy/vigor [genki] and bravery [yuuki], and being in one’s right mind [shouki; could also be translated as "true character"] (note 11). There’s a limit to physical strength, no matter how much you toughen it up, and the only way to overcome that it is with “ki”. I think that it was through turning ki into formidable power that Goku drew closer to being the strongest warrior in the universe.
Also in DBZ gravity/weight training is all about stamina and physical muscle not ki, this is why they train in not not so impressive gravities, it's to strengthen their bodies so it can handle more ki. So yeah Goku's strength limit when not using ki is roughly 40 tons. (and yeah lifting strength =/= striking strength)
This is why base kid Trunks was struggling in 150g (weighing 4 tons) while base namek saga Goku had mastered 100g training (weighing 7 tons). Even though with ki base kid Trunks is much stronger than base namek saga Goku, without ki he's physically weaker than him.
Holy shit how do you make images visible here!?
