I trained in the hyperbolic time chamber for 3 years and only 3 days passed in the real time?

Question

But yet....I still feel not that strong yet. What could be my problem?

Answer 1

That's some gravity. I bet you reached Super Saiyan 3, didn't you? You probably are even beyond that, but still weaker then Gohan.

What does this have to do with Men's health, again?

Answer 2

its probably cos the earth doesnt currently face a threat important enough for the use of a uber saiyan.
