I do these kind of activities, but mostly divided in 5 to 15mn chunks. (Notably, my commute to work is a mere 10mn walk and I have a toddler child at home requiring frequent attention)

I would have trouble dividing a 40mn podcast into five listens divided over 3 days.

For those kind of double-up, I find listening music vastly more enjoyable, but that's just my opinion. Lately I actually prefer not doubling-up and just listen to the silence and letting my mind wander. It feels good too !
