I couldn’t do 25 mph for two steps.
My tread mill taunts me every day.
As I wrote above, I’m pretty sure it means 2.5 mph. I couldn’t do 25 either. However, at 2.5, it’s still a fast walk for 20 minutes. It’s really worth it if just once or twice a week. Just start slowly for 10 minutes at no incline with heel to toe in sneakers - no bare feet. You’ll be amazed the next day how much energy you have. Then just slowly adjust to longer. Tell your treadmill who’s the Boss! I’m gonna tell mine right now.
