I know...

[svetlana14]

Dear all,

Please help me with identifying the phrase after the words "I know" number 15:12 in youtube related subtitles ([please click on the link).

Thank you very much

He says "I know. Can't you tell?" It's a self-deprecating way of saying that it might not be clear to the viewer, just by looking at him, that he has been going to the gym.

It's quite a neat line IMO.
