Why was Tenshinhan tired at the end of Chapter 209?

[SIAD]

I'm talking in the Manga, when they show Humans training in the Temple of Kami in a vignette.

They were facing Yamcha vs Chaoz.

Krillin was trying to hit a relaxed Mr. Popo.

Tenshinhan looked tired.

Seeing how Mr. Popo easily dodged Krillin's blows, it makes you think they were just starting training.

My question is, Tenshinhan will have faced Mr. Popo? Or was he just tired after doing arduous individual training?

Perhaps Popo had easily disposed of Tenshinhan and was doing the same thing to Krillin.

It is an option.

What do you think [mention]Captain Cadaver[/mention] ?

 

[Captain Cadaver]

Any idea on it is pure assumption with nothing really backing it up. He could've been training on his own, sparring with each of his peers or training against Popo. Any idea has as much weight as the other when all we have to go off is a single panel.
