Stair Climbing

My weekly stair climbing. This time, same 40 storey building but extend to going up 3 times. Total is 117 storeys.

I alternating going up 2-step a time vs 1-step a time for every 4 storeys. Therefore, you can see the saw-tooth effect on the heart rate. When I reached the top, I took the lift back to level 1 and start again.

Condition is still good after climbing up the 117 storeys. I can still run the 400m back home.
