Picking it up a bit more.

40 trips. up and down the two flights, two steps at a time.
Time: 23:32
Avg heart rate: 165

Time splits were about the same as yesterday at the 20, 24 and 30 marks. Wasn't feeling bad, so I went an extra 10 trips up and down. So 33% better than yesterday, and twice what I did two days ago. It's really not cold enough inside the building yet, and I'm baking toward the end of the session.

I'm really looking forward to some cooler temps. Thinking of getting some cross-country skis and letting the Husky pull me around a bit!
