Still probably would not do it. But why?

I wonder what other exercise modality this could be replaced with. Do 3 squats?

Sprinting up a flight of stairs, then walking back down, and repeating it five times, once an hour.

That I have a good gauge of. Yeah, that would feel good. Pity I live in a first-floor flat...
