24 minutes to climb the stairs, 68 floors!

I couldn't go to the swimming pool, so I climbed the stairs instead.

I'm going to work up a sweat and take a shower.

I climbed 68 floors in 24 minutes, 17 floors four times.

I feel like my legs would be shaking if I did it one more time, so I stopped here!

Your heart rate has gone up quite a bit!

I should do it regularly, even if not every day.
