OK, bear with me. I'm an old man and jogging isn't something I want to try. OK, only 48 but I fell older when I try to run.
Every morning first thing I take a walk. It is a brisk walk up and down a steep hill near my house. It take about 5 minutes to do a lap from top to bottom and back again. Each lap, I am defintely sucking wind near the top on the steepest incline. So I am walking fast, not strolling. I do 8 laps a day and spend about 45 minutes total from house to hill and back.
Does this count as cardio? Do I need to do jogging or something else to truly drop weight and improve stamina?
