Works the whole body, has to be done regularly, cardio but not extreme, physical but not extreme. Less dangerous that rock climbing. Big lawn, in season. We all make fitness goals, decisions, actions from a slightly different point of view. I upgraded to an e-mower.

Ride on. 
Yeah I'm getting rid of my old school reel push mower for an e-mower. I figure it will help free up time for more bike riding.
Insofar as bike riding is concerned, I don't tend to spend too much time in my peak zones. I do look for hills to ride though as much as possible.
