Oh crazy, even the bottom is in Korean.

Black bubble:

에너지 아끼고 건강도 챙기고

Google translate:

Save energy and take care of your health.

Circled bubble in the white box:

생활 속 헬스장

Google translate:

Gym in your life.

Then the bottom:

계단올 두 칸 오를 때 미다

Google translate:

Every time you climb two steps

And then just documents how much energy you burn.

I'd attempt to actually translate it myself, but I honestly don't trust my vocab so I went with the Google translation, which is close enough.
